French language

French ( français [fʁɑ̃sɛ] or langue française [lɑ̃ɡ fʁɑ̃sɛːz] ) is a Romance language of the Indo-European family. Like all other Romance languages, it descended from the Vulgar Latin of the Roman Empire. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to the French colonial empire, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French.

French is an official language in 27 countries, as well as one of the most geographically widespread languages in the world, with about 50 countries and territories having it as a de jure or de facto official, administrative, or cultural language. Most of these countries are members of the Organisation internationale de la Francophonie (OIF), the community of 54 member states which share the official use or teaching of French. It is spoken as a first language (in descending order of the number of speakers) in France; Canada (especially in the provinces of Quebec, Ontario, and New Brunswick); Belgium (Wallonia and the Brussels-Capital Region); western Switzerland (specifically the cantons forming the Romandy region); parts of Luxembourg; parts of the United States (the states of Louisiana, Maine, New Hampshire, and Vermont); Monaco; the Aosta Valley region of Italy; and various communities elsewhere.

French is estimated to have about 310 million speakers, of which about 80 million are native speakers. According to the OIF, approximately 321 million people worldwide are "able to speak the language" as of 2022, without specifying the criteria for this estimation or whom it encompasses.

In Francophone Africa, it is spoken mainly as a second language. However it has also become a native language in a number of urban areas, especially in regions like Ivory Coast, Cameroon, Gabon, Madagascar, and the Democratic Republic of the Congo. In some North African countries, though not having official status, it is also a first language among some upper classes of the population alongside indigenous languages, but only a second one among the general population.

In 2015, approximately 40% of the Francophone population (including L2 and partial speakers) lived in Europe, 36% in sub-Saharan Africa and the Indian Ocean, 15% in North Africa and the Middle East, 8% in the Americas, and 1% in Asia and Oceania. French is the second most widely spoken mother tongue in the European Union. Of Europeans who speak other languages natively, approximately one-fifth are able to speak French as a second language. French is the second most taught foreign language in the EU. All institutions of the EU use French as a working language along with English and German; in some institutions, French is the sole working language (e.g. at the Court of Justice of the European Union). French is also the 16th most natively spoken language in the world, the sixth most spoken language by total number of speakers, and is among the top five most studied languages worldwide, with about 120 million learners as of 2017. As a result of French and Belgian colonialism from the 16th century onward, French was introduced to new territories in the Americas, Africa, and Asia. French has a long history as an international language of literature and scientific standards and is a primary or second language of many international organisations including the United Nations, the European Union, the North Atlantic Treaty Organization, the World Trade Organization, the International Olympic Committee, the General Conference on Weights and Measures, and the International Committee of the Red Cross.

French is a Romance language (meaning that it is descended primarily from Vulgar Latin) that evolved out of the Gallo-Romance dialects spoken in northern France. The language's early forms include Old French and Middle French.

Due to Roman rule, Latin was gradually adopted by the inhabitants of Gaul. As the language was learned by the common people, it developed a distinct local character, with grammatical differences from Latin as spoken elsewhere, some of which is attested in graffiti. This local variety evolved into the Gallo-Romance tongues, which include French and its closest relatives, such as Arpitan.

The evolution of Latin in Gaul was shaped by its coexistence for over half a millennium beside the native Celtic Gaulish language, which did not go extinct until the late sixth century, long after the fall of the Western Roman Empire. The population remained 90% indigenous in origin; the Romanizing class were the local native elite (not Roman settlers), whose children learned Latin in Roman schools. At the time of the collapse of the Empire, this local elite had been slowly abandoning Gaulish entirely, but the rural and lower class populations remained Gaulish speakers who could sometimes also speak Latin or Greek. The final language shift from Gaulish to Vulgar Latin among rural and lower class populations occurred later, when both they and the incoming Frankish ruler/military class adopted the Gallo-Roman Vulgar Latin speech of the urban intellectual elite.

The Gaulish language likely survived into the sixth century in France despite considerable Romanization. Coexisting with Latin, Gaulish helped shape the Vulgar Latin dialects that developed into French contributing loanwords and calques (including oui , the word for "yes"), sound changes shaped by Gaulish influence, and influences in conjugation and word order. Recent computational studies suggest that early gender shifts may have been motivated by the gender of the corresponding word in Gaulish.

The estimated number of French words that can be attributed to Gaulish is placed at 154 by the Petit Robert, which is often viewed as representing standardized French, while if non-standard dialects are included, the number increases to 240. Known Gaulish loans are skewed toward certain semantic fields, such as plant life (chêne, bille, etc.), animals (mouton, cheval, etc.), nature (boue, etc.), domestic activities (ex. berceau), farming and rural units of measure (arpent, lieue, borne, boisseau), weapons, and products traded regionally rather than further afield. This semantic distribution has been attributed to peasants being the last to hold onto Gaulish.

The beginning of French in Gaul was greatly influenced by Germanic invasions into the country. These invasions had the greatest impact on the northern part of the country and on the language there. A language divide began to grow across the country. The population in the north spoke langue d'oïl while the population in the south spoke langue d'oc . Langue d'oïl grew into what is known as Old French. The period of Old French spanned between the 8th and 14th centuries. Old French shared many characteristics with Latin. For example, Old French made use of different possible word orders just as Latin did because it had a case system that retained the difference between nominative subjects and oblique non-subjects. The period is marked by a heavy superstrate influence from the Germanic Frankish language, which non-exhaustively included the use in upper-class speech and higher registers of V2 word order, a large percentage of the vocabulary (now at around 15% of modern French vocabulary ) including the impersonal singular pronoun on (a calque of Germanic man), and the name of the language itself.

Up until its later stages, Old French, alongside Old Occitan, maintained a relic of the old nominal case system of Latin longer than most other Romance languages (with the notable exception of Romanian which still currently maintains a case distinction), differentiating between an oblique case and a nominative case. The phonology was characterized by heavy syllabic stress, which led to the emergence of various complicated diphthongs such as -eau which would later be leveled to monophthongs.

The earliest evidence of what became Old French can be seen in the Oaths of Strasbourg and the Sequence of Saint Eulalia, while Old French literature began to be produced in the eleventh century, with major early works often focusing on the lives of saints (such as the Vie de Saint Alexis), or wars and royal courts, notably including the Chanson de Roland, epic cycles focused on King Arthur and his court, as well as a cycle focused on William of Orange.

It was during the period of the Crusades in which French became so dominant in the Mediterranean Sea that became a lingua franca ("Frankish language"), and because of increased contact with the Arabs during the Crusades who referred to them as Franj, numerous Arabic loanwords entered French, such as amiral (admiral), alcool (alcohol), coton (cotton) and sirop (syrop), as well as scientific terms such as algébre (algebra), alchimie (alchemy) and zéro (zero).

Within Old French many dialects emerged but the Francien dialect is one that not only continued but also thrived during the Middle French period (14th–17th centuries). Modern French grew out of this Francien dialect. Grammatically, during the period of Middle French, noun declensions were lost and there began to be standardized rules. Robert Estienne published the first Latin-French dictionary, which included information about phonetics, etymology, and grammar. Politically, the first government authority to adopt Modern French as official was the Aosta Valley in 1536, while the Ordinance of Villers-Cotterêts (1539) named French the language of law in the Kingdom of France.

During the 17th century, French replaced Latin as the most important language of diplomacy and international relations (lingua franca). It retained this role until approximately the middle of the 20th century, when it was replaced by English as the United States became the dominant global power following the Second World War. Stanley Meisler of the Los Angeles Times said that the fact that the Treaty of Versailles was written in English as well as French was the "first diplomatic blow" against the language.

During the Grand Siècle (17th century), France, under the rule of powerful leaders such as Cardinal Richelieu and Louis XIV, enjoyed a period of prosperity and prominence among European nations. Richelieu established the Académie française to protect the French language. By the early 1800s, Parisian French had become the primary language of the aristocracy in France.

Near the beginning of the 19th century, the French government began to pursue policies with the end goal of eradicating the many minorities and regional languages (patois) spoken in France. This began in 1794 with Henri Grégoire's "Report on the necessity and means to annihilate the patois and to universalize the use of the French language". When public education was made compulsory, only French was taught and the use of any other (patois) language was punished. The goals of the public school system were made especially clear to the French-speaking teachers sent to teach students in regions such as Occitania and Brittany. Instructions given by a French official to teachers in the department of Finistère, in western Brittany, included the following: "And remember, Gents: you were given your position in order to kill the Breton language". The prefect of Basses-Pyrénées in the French Basque Country wrote in 1846: "Our schools in the Basque Country are particularly meant to replace the Basque language with French..." Students were taught that their ancestral languages were inferior and they should be ashamed of them; this process was known in the Occitan-speaking region as Vergonha.

Spoken by 19.71% of the European Union's population, French is the third most widely spoken language in the EU, after English and German and the second-most-widely taught language after English.

Under the Constitution of France, French has been the official language of the Republic since 1992, although the Ordinance of Villers-Cotterêts made it mandatory for legal documents in 1539. France mandates the use of French in official government publications, public education except in specific cases, and legal contracts; advertisements must bear a translation of foreign words.

In Belgium, French is an official language at the federal level along with Dutch and German. At the regional level, French is the sole official language of Wallonia (excluding a part of the East Cantons, which are German-speaking) and one of the two official languages—along with Dutch—of the Brussels-Capital Region, where it is spoken by the majority of the population (approx. 80%), often as their primary language.

French is one of the four official languages of Switzerland, along with German, Italian, and Romansh, and is spoken in the western part of Switzerland, called Romandy, of which Geneva is the largest city. The language divisions in Switzerland do not coincide with political subdivisions, and some cantons have bilingual status: for example, cities such as Biel/Bienne and cantons such as Valais, Fribourg and Bern. French is the native language of about 23% of the Swiss population, and is spoken by 50% of the population.

Along with Luxembourgish and German, French is one of the three official languages of Luxembourg, where it is generally the preferred language of business as well as of the different public administrations. It is also the official language of Monaco.

At a regional level, French is acknowledged as an official language in the Aosta Valley region of Italy where it is the first language of approximately 50% of the population, while French dialects remain spoken by minorities on the Channel Islands. It is also spoken in Andorra and is the main language after Catalan in El Pas de la Casa. The language is taught as the primary second language in the German state of Saarland, with French being taught from pre-school and over 43% of citizens being able to speak French.

The majority of the world's French-speaking population lives in Africa. According to a 2023 estimate from the Organisation internationale de la Francophonie , an estimated 167 million African people spread across 35 countries and territories can speak French as either a first or a second language. This number does not include the people living in non-Francophone African countries who have learned French as a foreign language. Due to the rise of French in Africa, the total French-speaking population worldwide is expected to reach 700 million people in 2050. French is the fastest growing language on the continent (in terms of either official or foreign languages).

French is increasingly being spoken as a native language in Francophone Africa, especially in regions like Ivory Coast, Cameroon, Gabon, Madagascar, and the Democratic Republic of Congo.

There is not a single African French, but multiple forms that diverged through contact with various indigenous African languages.

Sub-Saharan Africa is the region where the French language is most likely to expand, because of the expansion of education and rapid population growth. It is also where the language has evolved the most in recent years. Some vernacular forms of French in Africa can be difficult to understand for French speakers from other countries, but written forms of the language are very closely related to those of the rest of the French-speaking world.

French is the second most commonly spoken language in Canada and one of two federal official languages alongside English. As of the 2021 Canadian census, it was the native language of 7.7 million people (21% of the population) and the second language of 2.9 million (8% of the population). French is the sole official language in the province of Quebec, where some 80% of the population speak it as a native language and 95% are capable of conducting a conversation in it. Quebec is also home to the city of Montreal, which is the world's fourth-largest French-speaking city, by number of first language speakers. New Brunswick and Manitoba are the only officially bilingual provinces, though full bilingualism is enacted only in New Brunswick, where about one third of the population is Francophone. French is also an official language of all of the territories (Northwest Territories, Nunavut, and Yukon). Out of the three, Yukon has the most French speakers, making up just under 4% of the population. Furthermore, while French is not an official language in Ontario, the French Language Services Act ensures that provincial services are available in the language. The Act applies to areas of the province where there are significant Francophone communities, namely Eastern Ontario and Northern Ontario. Elsewhere, sizable French-speaking minorities are found in southern Manitoba, Nova Scotia, Prince Edward Island and the Port au Port Peninsula in Newfoundland and Labrador, where the unique Newfoundland French dialect was historically spoken. Smaller pockets of French speakers exist in all other provinces. The Ontarian city of Ottawa, the Canadian capital, is also effectively bilingual, as it has a large population of federal government workers, who are required to offer services in both French and English, and is just across the river from the Quebecois city of Gatineau.

According to the United States Census Bureau (2011), French is the fourth most spoken language in the United States after English, Spanish, and Chinese, when all forms of French are considered together and all dialects of Chinese are similarly combined. French is the second-most spoken language (after English) in the states of Maine and New Hampshire. In Louisiana, it is tied with Spanish for second-most spoken if Louisiana French and all creoles such as Haitian are included. French is the third most spoken language (after English and Spanish) in the states of Connecticut, Rhode Island, and New Hampshire. Louisiana is home to many distinct French dialects, collectively known as Louisiana French. New England French, essentially a variant of Canadian French, is spoken in parts of New England. Missouri French was historically spoken in Missouri and Illinois (formerly known as Upper Louisiana), but is nearly extinct today. French also survived in isolated pockets along the Gulf Coast of what was previously French Lower Louisiana, such as Mon Louis Island, Alabama and DeLisle, Mississippi (the latter only being discovered by linguists in the 1990s) but these varieties are severely endangered or presumed extinct.

French is one of two official languages in Haiti alongside Haitian Creole. It is the principal language of education, administration, business, and public signage and is spoken by all educated Haitians. It is also used for ceremonial events such as weddings, graduations, and church masses. The vast majority of the population speaks Haitian Creole as their first language; the rest largely speak French as a first language. As a French Creole language, Haitian Creole draws the large majority of its vocabulary from French, with influences from West African languages, as well as several European languages. It is closely related to Louisiana Creole and the creole from the Lesser Antilles.

French is the sole official language of all the overseas territories of France in the Caribbean that are collectively referred to as the French West Indies, namely Guadeloupe, Saint Barthélemy, Saint Martin, and Martinique.

French is the official language of both French Guiana on the South American continent, and of Saint Pierre and Miquelon, an archipelago off the coast of Newfoundland in North America.

French was the official language of the colony of French Indochina, comprising modern-day Vietnam, Laos, and Cambodia. It continues to be an administrative language in Laos and Cambodia, although its influence has waned in recent decades. In colonial Vietnam, the elites primarily spoke French, while many servants who worked in French households spoke a French pidgin known as "Tây Bồi" (now extinct). After French rule ended, South Vietnam continued to use French in administration, education, and trade. However, since the Fall of Saigon and the opening of a unified Vietnam's economy, French has gradually been effectively displaced as the first foreign language of choice by English in Vietnam. Nevertheless, it continues to be taught as the other main foreign language in the Vietnamese educational system and is regarded as a cultural language. All three countries are full members of La Francophonie (OIF).

French was the official language of French India, consisting of the geographically separate enclaves referred to as Puducherry. It continued to be an official language of the territory even after its cession to India in 1956 until 1965. A small number of older locals still retain knowledge of the language, although it has now given way to Tamil and English.

A former French mandate, Lebanon designates Arabic as the sole official language, while a special law regulates cases when French can be publicly used. Article 11 of Lebanon's Constitution states that "Arabic is the official national language. A law determines the cases in which the French language is to be used". The French language in Lebanon is a widespread second language among the Lebanese people, and is taught in many schools along with Arabic and English. French is used on Lebanese pound banknotes, on road signs, on Lebanese license plates, and on official buildings (alongside Arabic).

Today, French and English are secondary languages of Lebanon, with about 40% of the population being Francophone and 40% Anglophone. The use of English is growing in the business and media environment. Out of about 900,000 students, about 500,000 are enrolled in Francophone schools, public or private, in which the teaching of mathematics and scientific subjects is provided in French. Actual usage of French varies depending on the region and social status. One-third of high school students educated in French go on to pursue higher education in English-speaking institutions. English is the language of business and communication, with French being an element of social distinction, chosen for its emotional value.

French is an official language of the Pacific Island nation of Vanuatu, where 31% of the population was estimated to speak it in 2023. In the French special collectivity of New Caledonia, 97% of the population can speak, read and write French while in French Polynesia this figure is 95%, and in the French collectivity of Wallis and Futuna, it is 84%.

In French Polynesia and to a lesser extent Wallis and Futuna, where oral and written knowledge of the French language has become almost universal (95% and 84% respectively), French increasingly tends to displace the native Polynesian languages as the language most spoken at home. In French Polynesia, the percentage of the population who reported that French was the language they use the most at home rose from 67% at the 2007 census to 74% at the 2017 census. In Wallis and Futuna, the percentage of the population who reported that French was the language they use the most at home rose from 10% at the 2008 census to 13% at the 2018 census.

According to a demographic projection led by the Université Laval and the Réseau Démographie de l'Agence universitaire de la Francophonie, the total number of French speakers will reach approximately 500 million in 2025 and 650 million by 2050, largely due to rapid population growth in sub-Saharan Africa. OIF estimates 700 million French speakers by 2050, 80% of whom will be in Africa.

In a study published in March 2014 by Forbes, the investment bank Natixis said that French could become the world's most spoken language by 2050.

In the European Union, French was the dominant language within all institutions until the 1990s. After several enlargements of the EU (1995, 2004), French significantly lost ground in favour of English, which is more widely spoken and taught in most EU countries. French currently remains one of the three working languages, or "procedural languages", of the EU, along with English and German. It is the second-most widely used language within EU institutions after English, but remains the preferred language of certain institutions or administrations such as the Court of Justice of the European Union, where it is the sole internal working language, or the Directorate-General for Agriculture. Since 2016, Brexit has rekindled discussions on whether or not French should again hold greater role within the institutions of the European Union.

A leading world language, French is taught in universities around the world, and is one of the world's most influential languages because of its wide use in the worlds of journalism, jurisprudence, education, and diplomacy. In diplomacy, French is one of the six official languages of the United Nations (and one of the UN Secretariat's only two working languages ), one of twenty official and three procedural languages of the European Union, an official language of NATO, the International Olympic Committee, the Council of Europe, the Organisation for Economic Co-operation and Development, Organization of American States (alongside Spanish, Portuguese and English), the Eurovision Song Contest, one of eighteen official languages of the European Space Agency, World Trade Organization and the least used of the three official languages in the North American Free Trade Agreement countries. It is also a working language in nonprofit organisations such as the Red Cross (alongside English, German, Spanish, Portuguese, Arabic and Russian), Amnesty International (alongside 32 other languages of which English is the most used, followed by Spanish, Portuguese, German, and Italian), Médecins sans Frontières (used alongside English, Spanish, Portuguese and Arabic), and Médecins du Monde (used alongside English). Given the demographic prospects of the French-speaking nations of Africa, researcher Pascal-Emmanuel Gobry wrote in 2014 that French "could be the language of the future". However, some African countries such as Algeria intermittently attempted to eradicate the use of French, and as of 2024 it was removed as an official language in Mali and Burkina Faso.

Significant as a judicial language, French is one of the official languages of such major international and regional courts, tribunals, and dispute-settlement bodies as the African Court on Human and Peoples' Rights, the Caribbean Court of Justice, the Court of Justice for the Economic Community of West African States, the Inter-American Court of Human Rights, the International Court of Justice, the International Criminal Tribunal for the former Yugoslavia, International Criminal Tribunal for Rwanda, the International Tribunal for the Law of the Sea the International Criminal Court and the World Trade Organization Appellate Body. It is the sole internal working language of the Court of Justice of the European Union, and makes with English the European Court of Human Rights's two working languages.

In 1997, George Weber published, in Language Today, a comprehensive academic study entitled "The World's 10 most influential languages". In the article, Weber ranked French as, after English, the second-most influential language of the world, ahead of Spanish. His criteria were the numbers of native speakers, the number of secondary speakers (especially high for French among fellow world languages), the number of countries using the language and their respective populations, the economic power of the countries using the language, the number of major areas in which the language is used, and the linguistic prestige associated with the mastery of the language (Weber highlighted that French in particular enjoys considerable linguistic prestige). In a 2008 reassessment of his article, Weber concluded that his findings were still correct since "the situation among the top ten remains unchanged."

Knowledge of French is often considered to be a useful skill by business owners in the United Kingdom; a 2014 study found that 50% of British managers considered French to be a valuable asset for their business, thus ranking French as the most sought-after foreign language there, ahead of German (49%) and Spanish (44%). MIT economist Albert Saiz calculated a 2.3% premium for those who have French as a foreign language in the workplace.

In 2011, Bloomberg Businessweek ranked French the third most useful language for business, after English and Standard Mandarin Chinese.

In English-speaking Canada, the United Kingdom, and Ireland, French is the first foreign language taught and in number of pupils is far ahead of other languages. In the United States, French is the second-most commonly taught foreign language in schools and universities, although well behind Spanish. In some areas of the country near French-speaking Quebec, however, it is the foreign language more commonly taught.

Wallonia

Wallonia ( / w ɒ ˈ l oʊ n i ə / wol- OH -nee-ə; French: Wallonie [walɔni] ; Walloon: Waloneye or Walonreye ), officially the Walloon Region (French: Région wallonne; Walloon: Redjon walone), is one of the three regions of Belgium—along with Flanders and Brussels. Covering the southern portion of the country, Wallonia is primarily French-speaking. It accounts for 55% of Belgium's territory, but only a third of its population. The Walloon Region and the French Community of Belgium, which is the political entity responsible for matters related mainly to culture and education, are independent concepts, because the French Community of Belgium encompasses both Wallonia and the bilingual Brussels-Capital Region but not the German-speaking Community of Belgium.

During the Industrial Revolution, Wallonia was second only to the United Kingdom in industrialization, capitalizing on its extensive deposits of coal and iron. This brought the region wealth, and from the beginning of the 19th to the middle of the 20th century, Wallonia was the more prosperous half of Belgium. Since World War II, the importance of heavy industry has greatly diminished, and the Flemish Region has exceeded Wallonia in wealth as Wallonia has declined economically. Wallonia now suffers from high unemployment and has a significantly lower GDP per capita than Flanders. The economic inequalities and linguistic divide between the two are major sources of political conflicts in Belgium and a major factor in Flemish separatism.

The capital of Wallonia is Namur, and the most populous city is Charleroi. Most of Wallonia's major cities and two-thirds of its population lie along the east–west aligned Sambre and Meuse valley, the former industrial backbone of Belgium. To the north of this valley, Wallonia lies on the Central Belgian Plateau, which, like Flanders, is a relatively flat and agriculturally fertile area. The south and southeast of Wallonia is made up of the Ardennes, an expanse of forested highland that is less densely populated.

There is a German-speaking minority in eastern Wallonia, resulting from the annexation of three cantons previously part of the German Empire at the conclusion of World War I. This community represents less than 1% of the Belgian population. It forms the German-speaking Community of Belgium, which has its own government and parliament for culture-related issues.

Wallonia borders Flanders and the Netherlands (the province of Limburg) in the north, France (Grand Est and Hauts-de-France) to the south and west, and Germany (North Rhine-Westphalia and Rhineland-Palatinate) and Luxembourg (Capellen, Clervaux, Esch-sur-Alzette, Redange and Wiltz) to the east. Wallonia has been a member of the Organisation Internationale de la Francophonie since 1980.

The term "Wallonia" can mean slightly different things in different contexts. One of the three federal regions of Belgium is still constitutionally defined as the "Walloon Region" as opposed to "Wallonia", but the latter has been adopted by the regional government and is in common use. Prior to 2010, when the renaming came into effect, Wallonia could sometimes refer to the territory governed by the Walloon Region, whereas Walloon Region referred specifically to the government. In practice, the difference between the two terms is small and what is meant is usually clear, based on context.

Wallonia is a cognate of terms such as Wales, Cornwall and Wallachia. The Germanic word Walha, meaning the strangers, referred to Gallic or Celtic people. Wallonia is named after the Walloons, a group of locals who natively speak Romance languages. In Middle Dutch (and French), the term Walloons included both historical secular Walloon principalities, as well as the French-speaking population of the Prince-Bishopric of Liège or the whole population of the Romanic sprachraum within the medieval Low Countries.

Julius Caesar conquered Gaul in 57 BC. The Low Countries became part of the larger Gallia Belgica province which originally stretched from southwestern Germany to Normandy and the southern part of the Netherlands. The population of this territory was Celtic with a Germanic influence which was stronger in the north than in the south of the province. Gallia Belgica became progressively romanized. The ancestors of the Walloons became Gallo-Romans and were called the "Walha" by their Germanic neighbours. The "Walha" abandoned their Celtic dialects and started to speak Vulgar Latin.

The Merovingian Franks gradually gained control of the region during the 5th century, under Clovis. Due to the fragmentation of the former Roman Empire, Vulgar Latin regionally developed along different lines and evolved into several langue d'oïl dialects, which in Wallonia became Picard, Walloon and Lorrain. The oldest surviving text written in a langue d'oïl, the Sequence of Saint Eulalia, has characteristics of these three languages and was likely written in or very near to what is now Wallonia around 880 AD. From the 4th to the 7th century, the Franks established several settlements, probably mostly in the north of the province where the romanization was less advanced and some Germanic trace was still present. The language border (that now splits Belgium in the middle) began to crystallize between 700 under the reign of the Merovingians and Carolingians and around 1000 after the Ottonian Renaissance. French-speaking cities, with Liège as the largest one, appeared along the Meuse, while Gallo-Roman cities such as Tongeren, Maastricht and Aachen became Germanized.

The Carolingian dynasty dethroned the Merovingians in the 8th century. In 843, the Treaty of Verdun gave the territory of present-day Wallonia to Middle Francia, which would shortly fragment, with the region passing to Lotharingia. On Lotharingia's breakup in 959, the present-day territory of Belgium became part of Lower Lotharingia, which then fragmented into rival principalities and duchies by 1190. Literary Latin, which was taught in schools, lost its hegemony during the 13th century and was replaced by Old French.

In the 15th century, the Dukes of Burgundy took over the Low Countries. The death of Charles the Bold in 1477 raised the issue of succession, and the Liégeois took advantage of this to regain some of their autonomy. From the 16th to the 18th century, the Low Countries were governed successively by the Habsburg dynasty of Spain (from the early 16th century until 1713–14) and later by Austria (until 1794). This territory was enlarged in 1521–22 when Charles V, Holy Roman Emperor gained the Tournai region from France.

Present-day Belgium was conquered in 1795 by the French Republic during the French Revolutionary Wars. It was annexed to the Republic, which later became the Napoleonic Empire. After the Battle of Waterloo, Wallonia became part of the Kingdom of the Netherlands under King William of Orange. The Walloons played an active part in the Belgian Revolution in 1830. The Provisional Government of Belgium proclaimed Belgium's independence and held elections for the National Congress.

In the 19th century, the area began to industrialize, and Wallonia was the first fully industrialized area in continental Europe. This brought the region great economic prosperity, which was not mirrored in poorer Flanders and the result was a large amount of Flemish immigration to Wallonia. Belgium was divided into two divergent communities. On the one hand, the very Catholic Flemish society was characterized by an economy centred on agriculture; on the other hand, Wallonia was the centre of the continental European Industrial Revolution, where classical liberal and socialist movements were rapidly emerging. Major strikes and general strikes took place in Wallonia, including the Walloon jacquerie of 1886, the Belgian general strikes of 1893, 1902, 1913 (for universal suffrage), 1932 (depicted in Misère au Borinage), and 1936. After World War II, major strikes included the general strike against Leopold III of Belgium (1950), and the 1960-1961 Winter General Strike for autonomy for Wallonia.

The profitability of the heavy industries to which Wallonia owed its prosperity started declining in the first half of the 20th century, and the centre of industrial activity shifted north to Flanders. The loss of prosperity caused social unrest, and Wallonia sought greater autonomy in order to address its economic problems. In the wake of the 1960-1961 Winter General Strike, the process of state reform in Belgium got underway. This reform started partly with the linguistic laws of 1962–63, which defined the four language areas within the constitution. But the strikes of 1960 which took place in Wallonia more than in Flanders are not principally linked with the four language areas nor with the Communities but with the Regions. In 1968, the conflict between the communities burst out. French speakers in Flanders (who were not necessarily Walloons) were driven out of, most notably the Leuven-based Catholic University amid shouts of "Walen buiten!" ("Walloons out!"). After a formal split of the university in two and the creation of a brand new campus in Wallonia, a wider series of State reforms was passed in Belgium, which resulted in the federalisation of the nation and the creation of the Walloon Region and the French Community (comprising both Wallonia and Brussels), administrative entities each of which would gain various levels of considerable autonomy.

Wallonia is landlocked, with an area of 16,901 km (6,526 sq mi), or 55 percent of the total area of Belgium. The Sambre and Meuse valley, from Liège (70 m (230 ft)) to Charleroi (120 m (390 ft)) is an entrenched river in a fault line which separates Middle Belgium (elevation 100–200 m (330–660 ft)) and High Belgium (200–700 m (660–2,300 ft)). This fault line corresponds to a part of the southern coast of the late London-Brabant Massif. The valley, along with Haine and Vesdre valleys form the sillon industriel, the historical centre of the Belgian coalmining and steelmaking industry, and is also called the Walloon industrial backbone. Due to their long industrial historic record, several segments of the valley have received specific names: Borinage, around Mons, le Centre, around La Louvière, the Pays noir, around Charleroi and the Basse-Sambre, near Namur.

To the north of the Sambre and Meuse valley lies the Central Belgian plateau, which is characterized by intensive agriculture. The Walloon part of this plateau is traditionally divided into several regions: Walloon Brabant around Nivelles, Western Hainaut (French: Wallonie picarde, around Tournai), and Hesbaye around Waremme. South of the sillon industriel, the land is more rugged and is characterized by more extensive farming. It is traditionally divided into the regions of Entre-Sambre-et-Meuse, Condroz, Fagne-Famenne, the Ardennes and Land of Herve, as well as the Belgian Lorraine around Arlon and Virton. Dividing it into Condroz, Famenne, Calestienne, Ardennes (including Thiérache), and Belgian Lorraine (which includes the Gaume) is more reflective of the physical geography. The larger region, the Ardennes, is a thickly forested plateau with caves and small gorges. It is host to much of Belgium's wildlife but little agricultural capacity. This area extends westward into France and eastward to the Eifel in Germany via the High Fens plateau, on which the Signal de Botrange forms the highest point in Belgium at 694 metres (2,277 ft).

The Walloon region covers 16,901 km (6,526 sq mi) and is divided into five provinces, 20 arrondissements and 262 cities or municipalities.

The province of Walloon Brabant is the most recent one, being formed in 1995 after the splitting of the province of Brabant.

The largest cities in Wallonia are:

Contributions to the development of science and technology have appeared since the beginning of the country's history. The baptismal font of Renier de Huy is not the only example of medieval Walloon technical expertise: the words "houille" (coal) or "houilleur" (coal miner) or "grisou" (damp) were coined in Wallonia and are Walloon in origin.

The economically important very deep coal mining in the course of the First Industrial Revolution has required highly reputed specialized studies for mining engineers. But that was already the case before the Industrial Revolution, with an engineer as Rennequin Sualem for instance.

Engineer Zenobe Gramme invented the Gramme dynamo, the first generator to produce power on a commercial scale for industry. Chemist Ernest Solvay gave his name to the Solvay process for production of soda ash, an important chemical for many industrial uses. Ernest Solvay also acted as a major philanthropist and gave its name to the Solvay Institute of Sociology, the Solvay Brussels School of Economics and Management and the International Solvay Institutes for Physics and Chemistry which are now part of the Université libre de Bruxelles. In 1911, he started a series of conferences, the Solvay Conferences on Physics and Chemistry, which have had a deep impact on the evolution of quantum physics and chemistry.

Georges Lemaître of the Université catholique de Louvain is credited with proposing the Big Bang theory of the origin of the universe in 1927.

Three Nobel Prizes in Physiology or Medicine were awarded to Walloons: Jules Bordet (Université libre de Bruxelles) in 1919, Albert Claude (ULB) together with Christian De Duve (UCLouvain) in 1974.

In the present day, Bureau Greisch has acquired an international reputation as consulting engineer and architect in the fields of structures, civil engineering and buildings, including the Millau Viaduct in France.

Wallonia is rich in iron and coal, and these resources and related industries have played an important role in its history. In ancient times, the Sambre and Meuse valley was an important industrial area in the Roman Empire. In the Middle Ages, Wallonia became a center for brass working and bronze working, with Huy, Dinant and Chimay being important regional centers. In the 12th and 13th centuries, the iron masters of Liège developed a method of refining iron ore by the use of a blast furnace, called the Walloon Method. There were also a few coal mines around Charleroi and the Borinage during this period, but their output was small, and was principally consumed as fuel by various industries such as the important glassmaking industry that sprang up in the Charleroi basin during the 14th century.

In the 19th century, the area began to industrialize, mainly along the so-called sillon industriel. It was the first fully industrialized area in continental Europe, and Wallonia was the second industrial power in the world, in proportion to its population and its territory, after the United Kingdom. The sole industrial centre in Belgium outside the collieries and blast furnaces of Wallonia was the historic cloth making town of Ghent.

The two World Wars curbed the continuous expansion that Wallonia had enjoyed up till that time. Towards the end of the 1950s, things began to change dramatically. The factories of Wallonia were by then antiquated, the coal was running out and the cost of extracting coal was constantly rising. It was the end of an era, and Wallonia has been making efforts to redefine itself. The restoration of economical development is high on the political agenda, and the government is encouraging development of industries, notably in cutting-edge technology and in business parks. The economy is improving, but Wallonia is not yet at the level of Flanders and is still suffering from difficulties.

The current Walloon economy is relatively diversified, although certain areas (especially around Charleroi and Liège) are still suffering from the steel industry crisis, with an unemployment rate of up to 30 percent. Nonetheless, Wallonia has some companies which are world leaders in their specialized fields, including armaments, glass production, lime and limestone production, cyclotrons and aviation parts. The south of Wallonia, bordering Luxembourg, benefits from its neighbour's economic prosperity, with many Belgians working on the other side of the border; they are often called frontaliers. The Ardennes area south of the Meuse is a popular tourist destination for its nature and outdoor sports, in addition to its cultural heritage, with places such as Bastogne, Dinant, Durbuy, and the famous hot springs of Spa.

The Gross domestic product (GDP) of the region was 105.7 billion € in 2018, accounting for 23% of Belgian economic output. GDP per capita adjusted for purchasing power was €25,700 or 85% of the EU27 average in the same year.

Belgium is a federal state made up of three communities and three regions, each with considerable autonomy. One of these is the Walloon Region, which is governed by the Parliament of Wallonia and the executive Government of Wallonia. The Walloon Region's autonomy extends even to foreign policy; Wallonia is entitled to pursue its own foreign policy, including the signing of treaties, and in many domains, even the Belgian federal government is not able to sign an international treaty without the agreement of the Parliament of Wallonia.

Wallonia is also home to about 80 per cent of the population of the French Community of Belgium, a political level responsible for matters related mainly to culture and education, with the remainder living in Brussels. Wallonia is also home to the small German-speaking Community of Belgium in the east, which has its own government and parliament for culture-related issues. Although in Flanders, the Flemish Region assigned all of its powers to the Flemish Community, the Walloon Region remains in principle distinct from and independent from the French Community, and vice versa. Despite this, the French Community's parliament is almost entirely composed of members of Wallonia's and Brussels' parliaments, so the bodies are governed by the same individuals. Additionally, the French Community of Belgium has controversially begun referring to itself exclusively as the 'Wallonia-Brussels Federation' to emphasize the links between the French Community, Wallonia and Brussels.

The Walloon Region has a unicameral parliament with 75 members elected for five years by direct universal suffrage, and an executive, the Government of Wallonia, elected by a political majority in Parliament. The Government has nine members with the president. Each member is called a Walloon minister. The head of the Government is called the Minister-President of Wallonia. The coalition government for the 2014–2019 legislature was a centre-left coalition PS-cdH until July 28 when it was replaced by a centre-left coalition MR-cdH. The current Minister-President is Elio Di Rupo.

Following several state reforms, especially the 1993 state reform, Belgium became a federal state made up of three communities and three regions, with Wallonia being represented by the Walloon Region and its two language communities. The directly elected Walloon Parliament was created in June 1995, replacing the Conseil régional wallon (Regional Council of Wallonia). The first Council had sat on 15 October 1980 and was composed of members of the Belgian Chamber of Representatives and the Belgian Senate elected in Wallonia.

Wallonia is considered to be left-wing politically, in contrast to Flanders, which is more right-wing. The region has been described as one of the few places in Europe without a significant right-wing populism presence. In Wallonia, there is a cordon sanitaire in the media, where far-right politicians are banned from interviews and live appearances. The ban has also affected more mainstream right-wing parties such as the N-VA.

The first appearance of the French word Wallonie as a reference to the romance world as opposed to Germany is said to date from 1842. Two years later, it was first used to refer to the Romance part of the young country of Belgium. In 1886, the writer and Walloon militant Albert Mockel, first used the word with a political meaning of cultural and regional affirmation, in opposition with the word Flanders used by the Flemish Movement. The word had previously appeared in German and Latin as early as the 17th century.

The rising of a Walloon identity led the Walloon Movement to choose different symbols representing Wallonia. The main symbol is the "bold rooster" (French: coq hardi), also named "Walloon rooster" (French: coq wallon, Walloon: cok walon), which is widely used, particularly on arms and flags. The rooster was chosen as an emblem by the Walloon Assembly on 20 April 1913, and designed by Pierre Paulus on 3 July 1913. The Flag of Wallonia features the red rooster on a yellow background.

An anthem, Le Chant des Wallons (The Walloons' Song), written by Theophile Bovy in 1900 and composed by Louis Hillier in 1901, was also adopted. On September 21, 1913, the "national" feast day of Wallonia took place for the first time in Verviers, commemorating the participation of Walloons during the Belgian Revolution of 1830. It is held annually on the third Sunday of September. The Assembly also chose a motto for Wallonia, "Walloon Forever" (Walloon: Walon todi), and a cry, "Liberty" (French: Liberté). In 1998, the Walloon Parliament made all these symbols official except the motto and the cry.

The population of Wallonia is predominantly of Christian heritage. In 2016, 68% of residents of Wallonia declared themselves to be Roman Catholic (21% were practising Catholics and 47% were non-practising), 3% were Muslim, 3% were Protestant Christian, 1% were of other religions and 25% were non-religious.

Religion in Wallonia (2016)

French is the official language of Wallonia and by far the most used; in the East Cantons, German is also official. The German-speaking Community of Belgium accounts for about 2% of the region's population. Belgian French, which is also spoken in the Brussels-Capital Region, is similar to that spoken in France, with slight differences in pronunciation and some vocabulary differences, notably the use of the words septante (70) and nonante (90), as opposed to soixante-dix and quatre-vingt-dix in France.

There are noticeable Walloon accents, with the accent from Liège and its surroundings being perhaps the most striking. Other regions of Wallonia also have characteristic accents, often linked to the regional language.

Walloons traditionally also speak regional Romance languages, all from the Langues d'oïl group. Wallonia includes almost all of the area where Walloon is spoken, a Picard zone corresponding to the major part of the Hainaut Province, the Gaume (district of Virton) with the Lorrain language and a Champenois zone. There are also regional Germanic languages, such as the Luxembourgish language in Arelerland (Land of Arlon). The regional languages of Wallonia are more important than in France, and they have been officially recognized by the government. With the development of education in French, however, these dialects have been in continual decline. There is currently an effort to revive Walloon dialects; some schools offer language courses in Walloon, and Walloon is also spoken in some radio programmes, but this effort remains very limited.

Literature is written principally in French but also in Walloon and other regional languages, colloquially called Walloon literature. Walloon literature (regional language not French) has been printed since the 16th century. But it did have its golden age, paradoxically, during the peak of the Flemish immigration to Wallonia in the 19th century: "That period saw an efflorescence of Walloon literature, plays and poems primarily, and the founding of many theaters and periodicals."

The New York Public Library possesses a surprisingly large collection of literary works in Walloon, quite possibly the largest outside Belgium, and its holding are representative of the output. Out of nearly a thousand, twenty-six were published before 1880. Thereafter the numbers rise gradually year by year, reaching a peak of sixty-nine in 1903, and then they fall again, down to eleven in 1913. See 'Switching Languages', p. 153. Yves Quairiaux counted 4800 plays for 1860–1914, published or not. In this period plays were almost the only popular show in Wallonia. But this theater remains popular in the present-day Wallonia: Theater is still flourishing, with over 200 non-professional companies playing in the cities and villages of Wallonia for an audience of over 200,000 each year.

There are links between French literature and (the very small) Walloon literature. For instance Raymond Queneau set Editions Gallimard the publication of a Walloon Poets' anthology. Ubu roi was translated in Walloon by André Blavier, a Verviers pataphysician, for the new and important Puppets theater of Liège of Jacques Ancion, the Al Botroûle theater "at the umbilical cord" in Walloon indicating a desire to return to the source (according to Joan Cross). But Jacques Ancion wanted to develop a regular adult audience. From the 19th century, he included the Walloon play Tati l'Pèriquî by E.Remouchamps and the avant-garde Ubu roi by A.Jarry.

For Jean-Marie Klinkenberg, "the dialectal culture is no more a sign of attachment to the past but a way to participate to a new synthesis".

Jean-Marie Klinkenberg (member of the Groupe μ) wrote that Wallonia, and literature in Wallonia, has been present in French language since its formation.
