A world-system is a socioeconomic system , under systems theory , that encompasses part or all of the globe, detailing the aggregate structural result of the sum of the interactions between polities . World-systems are usually larger than single states , but do not have to be global. The Westphalian System is the preeminent world-system operating in the contemporary world, denoting the system of sovereign states and nation-states produced by the Westphalian Treaties in 1648. Several world-systems can coexist, provided that they have little or no interaction with one another. Where such interactions becomes significant, separate world-systems merge into a new, larger world-system. Through the process of globalization , the modern world has reached the state of one dominant world-system, but in human history there have been periods where separate world-systems existed simultaneously, according to Janet Abu-Lughod . The most well-known version of the world-system approach has been developed by Immanuel Wallerstein . A world-system is a crucial element of the world-system theory , a multidisciplinary, macro-scale approach to world history and social change .
111-531: World-systems are defined by the existence of a division of labor. The modern world-system has a multi-state political structure (the interstate system ) and therefore its division of labor is international division of labor . In the modern world-system, the division of labor consists of three zones according to the prevalence of profitable industries or activities: core, semiperiphery, and periphery. Countries tend to fall into one or another of these interdependent zones core countries , semi-periphery countries and
222-770: A confederation of seafaring peoples contributed to the New Kingdom 's collapse in 1069 BC, commencing the Third Intermediate Period . Egypt's collapse liberated the more Egyptianised Kingdom of Kush in Nubia, who manoeuvred into power in Upper Egypt and conquered Lower Egypt in 754 BC to form the Kushite Empire . The Kushites ruled for a century and oversaw a revival in pyramid building , until they were driven out of Egypt by
333-557: A principality into a major power on the trade route between Rome and India through conquering its unfortunately unknown neighbours, gaining a monopoly on Indian Ocean trade in the region. Aksum's rise had them rule over much of the regions from Lake Tana to the valley of the Nile , and they further conquered parts of the ailing Kingdom of Kush , led campaigns against the Noba and Beja peoples, and expanded into South Arabia . This led
444-616: A Berber tribe originally from Yafran (also known as Ifrane ) in northwestern Libya , as well as the city of Ifrane in Morocco . Under Roman rule, Carthage became the capital of the province then named Africa Proconsularis , following its defeat of the Carthaginians in the Third Punic War in 146 BC, which also included the coastal part of modern Libya . The Latin suffix -ica can sometimes be used to denote
555-401: A capitalist world-economy at the national level. This has included claims that since an interstate system is the basis of a competitive commodity economy at a system level, then no single state is capable of totally ending commodity exchange across its borders without failing to maintain state competitiveness. Wallerstein believed that the fact that the eastern bloc had largely avoided disrupting
666-498: A crisis occurs, if a constellation of circumstances brings about the end of the system. The world-systems theory stresses that world-systems (and not nation states ) should be the basic unit of social analysis . Thus, we should focus not on individual states, but on the relations between their groupings (core, semi-periphery, and periphery). The most well-known version of the world-system approach has been developed by Immanuel Wallerstein , who has provided several definitions of what
777-710: A former Italian colony, gained independence. In 1956, Tunisia and Morocco won their independence from France. Ghana followed suit the next year (March 1957), becoming the first of the sub-Saharan colonies to be granted independence. Over the next decade, waves of decolonization took place across the continent, culminating in the 1960 Year of Africa and the establishment of the Organisation of African Unity in 1963. Portugal's overseas presence in sub-Saharan Africa (most notably in Angola , Cape Verde, Mozambique , Guinea-Bissau , and São Tomé and Príncipe) lasted from
888-409: A general controversy in the system, usually concerning some short term vs. long term trade-offs. For example, the problem of underconsumption , wherein the drive-down of wages increases the profit for the capitalists on the short-run, but considering the long run, the decreasing of wages may have a crucially harmful effect by reducing the demand for the product. The last temporal feature is the crisis :
999-448: A hegemon has achieved control over the interstate system, they assume world "responsibilities" to maintain the interstate system, restricting conflicts between entrepreneurial, bureaucratic and working-class strata by exercising power in a "liberal" form. This takes the form of greater enforcement of interstate rules to maintain liberal norms and the hegemon's diplomatic, military, political, ideological, and cultural power. This delegitimizes
1110-604: A hegemony over the world system. This generally requires a combined agro-industrial, commercial, and financial edge over their rivals, which has only been achieved by the Dutch Republic (1620–1672), the United Kingdom (1815–1873), and the United States (1945–1967). Such hegemonies coincide with expansions and contractions in the world economy, which Wallerstein explained through Kondratiev waves . Once

The later Muslim region of Ifriqiya , following its conquest of the Byzantine (Eastern Roman) Empire's Exarchatus Africae , also preserved a form of the name. According to the Romans, Africa lies to the west of Egypt, while "Asia" was used to refer to Anatolia and lands to the east. A definite line was drawn between

In modern-day Somalia and Djibouti there was the Macrobian Kingdom , with archaeological discoveries indicating the possibility of other unknown sophisticated civilisations at this time. After D'mt's fall in the 5th century BC the Ethiopian Plateau came to be ruled by numerous smaller unknown kingdoms who experienced strong south Arabian influence , until
1443-625: A monopoly on gold heading north and salt heading south, despite not controlling the gold fields themselves, located in the forest regions . It is probable that Wagadu's dominance on trade allowed for the gradual consolidation of many polities into a confederated state , whose composites stood in varying relations to the core, from fully administered to nominal tribute-paying parity. Based on large tumuli scattered across West Africa dating to this period, it has been stipulated that relative to Wagadu, there were further simultaneous and preceding kingdoms that have unfortunately been lost to time. At
1554-586: A native Libyan tribe, an ancestor of modern Berbers ; see Terence for discussion. The name had usually been connected with the Phoenician word ʿafar meaning "dust", but a 1981 hypothesis has asserted that it stems from the Berber word ifri (plural ifran ) meaning "cave", in reference to cave dwellers. The same word may be found in the name of the Banu Ifran from Algeria and Tripolitania ,
1665-468: A transition from " informal imperialism " – military influence and economic dominance – to direct rule. Imperial rule by Europeans continued until after the conclusion of World War II , when almost all remaining colonial territories gradually obtained formal independence. Independence movements in Africa gained momentum following World War II, which left the major European powers weakened. In 1951, Libya,
1776-438: A world-system is, twice in 1974, first "...a system is defined as a unit with a single division of labor and multiple cultural systems." and second as "…a social system, one that has boundaries, structures, member groups, rules of legitimation, and coherence." In 1987, he elaborated his definition: "...not the system of the world, but a system that is a world and which can be, most often has been, located in an area less than
1887-419: Is a large axial division of labor with multiple political centers and multiple cultures." Thus, we can differentiate world-systems into politically unified (world-empires) and not unified (world-economies). Small, non-state units such as tribes are micro-systems. World system refers to the entire world, whereas world-system is its fragment - the largest unit of analysis that makes sense. Wallerstein stresses
1998-791: Is not always to be taken literally. Africa is considered by most paleoanthropologists to be the oldest inhabited territory on Earth, with the Human species originating from the continent. During the mid-20th century, anthropologists discovered many fossils and evidence of human occupation perhaps as early as seven million years ago ( Before present , BP). Fossil remains of several species of early apelike humans thought to have evolved into modern humans, such as Australopithecus afarensis radiometrically dated to approximately 3.9–3.0 million years BP, Paranthropus boisei (c. 2.3–1.4 million years BP) and Homo ergaster (c. 1.9 million–600,000 years BP) have been discovered.

These institutions also created each other, as nations, classes, and households came to be defined by their relations to the state, and were subsequently able to shape the state. Out of this structural chaos on a sub-state level,
8325-400: The development of the capitalist world-system over the course of the "long" 16th century. The theory of the interstate system holds that all states are defined through their relationship to other states or through participation in the world economy , and that divisions between states help to divide the world into a core , periphery and semi-periphery . Immanuel Wallerstein wrote that
8436-428: The earliest instances of agriculture in human history. Its cultivation would gradually spread across Africa, before spreading to India around 2000 BC. People around modern-day Mauritania started making pottery and built stone settlements (e.g., Tichitt , Oualata ). Fishing, using bone-tipped harpoons , became a major activity in the numerous streams and lakes formed from the increased rains. In West Africa,
8547-483: The efforts of other state machineries to act against the hegemonic power. It is also self-defeating, in that it promotes the spread of technological expertise to other powers, and rising wages in the hegemon tends to decrease the competitiveness of its labor power. World-systems theorists have used the interstate system to explain the perceived failures of the state socialist economies of the eastern bloc in abolishing commodity fetishism and other negative effects of
8658-543: The end of the Ice ages , estimated to have been around 10,500 BC, the Sahara had again become a green fertile valley, and its African populations returned from the interior and coastal highlands in sub-Saharan Africa , with rock art paintings depicting a fertile Sahara and large populations discovered in Tassili n'Ajjer dating back perhaps 10 millennia. However, the warming and drying climate meant that by 5,000 BC,
8769-474: The entire globe. World-systems analysis argues that the units of social reality within which we operate, whose rules constrain us, are for the most part such world-systems [...]. ...there have been thus far only two varieties of world-systems: world-economies and world empires. A world-empire (examples, the Roman Empire , Han China ) are large bureaucratic structures with a single political center and an axial division of labor, but multiple cultures. A world-economy
8880-588: The evolution of Homo sapiens approximately 350,000 to 260,000 years BP in Africa, the continent was mainly populated by groups of hunter-gatherers . These first modern humans left Africa and populated the rest of the globe during the Out of Africa II migration dated to approximately 50,000 years BP, exiting the continent either across Bab-el-Mandeb over the Red Sea , the Strait of Gibraltar in Morocco, or
8991-660: The expansion of farming communities and the rapid adoption of rice cultivation around the Niger River. By the first millennium BC, ironworking had been introduced in Northern Africa. Around that time it also became established in parts of sub-Saharan Africa, either through independent invention there or diffusion from the north and vanished under unknown circumstances around 500 AD, having lasted approximately 2,000 years, and by 500 BC, metalworking began to become commonplace in West Africa. Ironworking
9102-420: The flow of capital, commodities and labor across borders to maintain the price structures of the global market. If weak states attempt to rewrite these rules as they prefer them, strong states will typically intervene to rectify the situation. The ideology of the interstate system is sovereign equality, and while the system generally presents a set of constraints on the power of individual states, states within
9213-434: The flows of capital, commodities and labor. There were also no clear rules about which group controlled the state, as various groups located inside, outside, and across the states’ frontiers could seek to increase or decrease state power in order to better profit from a world-economy. While on the level of individual states, almost nothing remained so stable as to assist with a definition of statehood, Wallerstein claimed that
9324-434: The form of creating institutions to affect state decisions, and that these institutions tend to be created within the boundaries of the state, and with a specific national scope. This has the effect of adding to the definiteness of state structures, and giving a national character to class conflict. Both the proletariat and bourgeoisie can find benefits and drawbacks to defining themselves as "world classes." For example,
9435-506: The growth and expansion of Aksum in the 1st century BC. Along the Horn's coast there were many ancient Somali city-states that thrived off of the wider Red Sea trade and transported their cargo via beden , exporting myrrh , frankincense , spices , gum , incense , and ivory , with freedom from Roman interference causing Indians to give the cities a lucrative monopoly on cinnamon from ancient India . The Kingdom of Aksum grew from
9546-443: The historical process is largely a communal one, with eyewitness accounts, hearsay , reminiscences, and occasionally visions , dreams, and hallucinations, crafted into oral traditions . Time is sometimes mythical and social, and truth generally viewed as relativist . Oral tradition can be exoteric or esoteric . It speaks to people according to their understanding, unveiling itself in accordance with their aptitudes, and
9657-464: The importance of hyphen in the title: "... In English, the hyphen is essential to indicate these concepts. "World system" without a hyphen suggests that there has been only one world-system in the history of the world." There is an ongoing debate among scholars whether we can talk about multiple world-systems. For those who support the multiple world-systems approach, there have been many world-systems throughout worlds history, some replacing others, as
9768-454: The interstate system as a mechanical consequence of capital accumulation . While Wallerstein was quite clear that the interstate system followed the development of a world-economy, and state policies largely reflected internal pressures from economic actors, other world-systems theorists like Christopher Chase-Dunn view the interstate system and world-economy as concomitant processes with no clear causal priority. Africa Africa
9879-572: The kingdoms of Lower Egypt and Upper Egypt in northeast Africa . Around 3100 BC Upper Egypt conquered Lower Egypt to unify Egypt under the 1st dynasty , with the process of consolidation and assimilation completed by the time of the 3rd dynasty who formed the Old Kingdom of Egypt in 2686 BC. The Kingdom of Kerma emerged around this time to become the dominant force in Nubia , controlling territory as large as Egypt between
9990-513: The largest number of megafauna species, as it was least affected by the extinction of the Pleistocene megafauna . However, Africa also is heavily affected by a wide range of environmental issues , including desertification, deforestation, water scarcity , and pollution . These entrenched environmental concerns are expected to worsen as climate change impacts Africa . The UN Intergovernmental Panel on Climate Change has identified Africa as
10101-616: The last 200 years, in Ethiopia . The domestication of cattle in Africa preceded agriculture and seems to have existed alongside hunter-gatherer cultures. It is speculated that by 6,000 BC, cattle were domesticated in North Africa. In the Sahara-Nile complex, people domesticated many animals, including the donkey and a small screw-horned goat that was common from Algeria to Nubia . Between 10,000 and 9,000 BC, pottery
10212-660: The most genetically diverse continent as a result of being the longest inhabited. In the 4th and 3rd millennia BC Ancient Egypt , Kerma , Punt , and the Tichitt Tradition emerged in North , East and West Africa , while from 4000 BC until 1000 AD the Bantu expansion was substantial in laying the foundations for societies and states in Central , East , and Southern Africa . Some African empires include Wagadu , Mali , Songhai , Sokoto , Ife , Benin , Asante ,
10323-399: The most lucrative trading locations in the Gulf of Tunis . Phoenician settlements subsequently grew into Ancient Carthage after gaining independence from Phoenicia in the 6th century BC, and they would build an extensive empire and a strict mercantile network, all secured by one of the largest and most powerful navies in the ancient Mediterranean . Carthage would meet its demise in
10434-439: The official religion, built mosques, and brought to Gao Muslim scholars, including al-Maghili (d.1504), the founder of an important tradition of Sudanic African Muslim scholarship. By the eleventh century, some Hausa states – such as Kano , Jigawa , Katsina , and Gobir – had developed into walled towns engaging in trade, servicing caravans , and the manufacture of goods. Until the fifteenth century, these small states were on
10545-465: The opportunities afforded by north–south diversity in ecosystems. Various civilisations prospered in this period. From 4000 BC, the Tichitt culture in modern-day Mauritania and Mali was the oldest known complexly organised society in West Africa, with a four tiered hierarchical social structure. Other civilisations include the Kintampo culture from 2500 BC in modern-day Ghana ,
10656-534: The periphery of the major Sudanic empires of the era, paying tribute to Songhai to the west and Kanem-Borno to the east. Slavery had long been practiced in Africa. Between the 15th and the 19th centuries, the Atlantic slave trade took an estimated 7–12 million slaves to the New World. In addition, more than 1 million Europeans were captured by Barbary pirates and sold as slaves in North Africa between
10767-599: The predecessor to the African Union. The nascent countries decided to keep their colonial borders, with traditional power structures used in governance to varying degrees. Afri was a Latin name used to refer to the inhabitants of what was then known as northern Africa , located west of the Nile river, and in its widest sense referring to all lands south of the Mediterranean , also known as Ancient Libya . This name seems to have originally referred to
10878-426: The process of globalization , many scholars agree that there has been only one world-system, that of capitalism . There are, however, dissenting voices, as some scholars do not support the contention that there is only one world-system in the modern day; Janet Abu-Lughod states that multiple world-systems did exist in past epochs. The alternative approach insists that there was only one World System that originated in
10989-480: The same fate as Carthage and be conquered by the Romans who established Mauretania and Numidia as provinces of their empire, while Musulamii , led by Tacfarinas , and Garamantes were eventually defeated in war in the 1st century AD however weren't conquered. In the 5th century AD the Vandals conquered north Africa precipitating the fall of Rome . Swathes of indigenous peoples would regain self-governance in
11100-424: The system are "neither sovereign nor equal." Not only do strong states impose their will on weak states, strong states also impose limitations upon other strong states, and tend to seek strengthened international rules, since enforcing consequences for broken rules can be highly beneficial and confer comparative advantages. Wallerstein notes that class conflict within the context of an interstate system tends to take
11211-488: The two continents by the geographer Ptolemy (85–165 CE), indicating Alexandria along the Prime Meridian and making the isthmus of Suez and the Red Sea the boundary between Asia and Africa. As Europeans came to understand the real extent of the continent, the idea of "Africa" expanded with their knowledge. Other etymological hypotheses have been postulated for the ancient name "Africa": In African societies,
11322-496: The unifying framework of Islam. Following the breakup of Mali, a local leader named Sonni Ali (1464–1492) founded the Songhai Empire in the region of middle Niger and the western Sudan and took control of the trans-Saharan trade. Sonni Ali seized Timbuktu in 1468 and Jenne in 1473, building his regime on trade revenues and the cooperation of Muslim merchants. His successor Askia Mohammad I (1493–1528) made Islam
11433-516: The wet phase ushered in an expanding rainforest and wooded savanna from Senegal to Cameroon . Between 9,000 and 5,000 BC, Niger–Congo speakers domesticated the oil palm and raffia palm . Black-eyed peas and voandzeia (African groundnuts), were domesticated, followed by okra and kola nuts . Since most of the plants grew in the forest, the Niger–Congo speakers invented polished stone axes for clearing forest. Around 4,000 BC,
11544-419: The world economy was proof of the effectiveness of the interstate system in disincentivizing global class conflict. Wallerstein's use of the interstate system to explain international relations was criticised by a number of Western Marxists and non-Marxists for what they saw as economism , or for failing to account for " the relative autonomy of the state " from economic factors, claiming that Wallerstein saw
11655-418: Was rapidly conquered and colonised by European nations , save for Ethiopia and Liberia . European rule had significant impacts on Africa's societies , and colonies were maintained for the purpose of economic exploitation and extraction of natural resources. Most present states emerged from a process of decolonisation following World War II , and established the Organisation of African Unity in 1963,
11766-503: Was established around the ninth century, making it one of the oldest kingdoms in present-day Nigeri. The Nri kingdom is famous for its elaborate bronzes , found at the town of Igbo-Ukwu . The Kingdom of Ife , historically the first of these Yoruba city-states or kingdoms, established government under a priestly oba ('king' or 'ruler' in the Yoruba language ), called the Ooni of Ife . Ife
11877-450: Was fully established by roughly 500 BC in many areas of East and West Africa, although other regions did not begin ironworking until the early centuries AD. Copper objects from Egypt , North Africa, Nubia, and Ethiopia dating from around 500 BC have been excavated in West Africa, suggesting that Trans-Saharan trade networks had been established by this date. From 3500 BC, nomes (ruled by nomarchs ) coalesced to form
11988-609: Was independently invented in the region of Mali in the savannah of West Africa. In the steppes and savannahs of the Sahara and Sahel in Northern West Africa, people possibly ancestral to modern Nilo-Saharan and Mandé cultures started to collect wild millet , around 8,000 to 6,000 BC. Later, gourds , watermelons , castor beans , and cotton were also collected. Sorghum was first domesticated in Eastern Sudan around 4,000 BC, in one of
12099-558: Was noted as a major religious and cultural centre in West Africa and for its unique naturalistic tradition of bronze sculpture. The Ife model of government was adapted by the Oyo Empire , whose obas, called the Alaafins of Oyo , controlled many other Yoruba and non-Yoruba city-states and kingdoms including the Fon Kingdom of Dahomey . The Almoravids were a Berber dynasty from the Sahara that spread over northwestern Africa and
12210-514: Was one of the first African countries to gain independence, the state remained under the control of the country's white minority, initially through qualified voting rights and from 1956 by a system of racial segregation known as apartheid , until 1994. Today, Africa contains 54 sovereign countries. Since independence, African states have frequently been hampered by instability, corruption, violence, and authoritarianism. The vast majority of African states are republics that operate under some form of
12321-533: Was the case when a multipolar world-system of the 13th-14th centuries was replaced by a series of consecutive Europe - and the West -centered world-systems. Others coexisted unknowingly with others, not linked to them directly or indirectly; in those cases the world-systems weren't worldwide (for example, prior to colonization of Americas , the Americas world-systems had no connection with the one encompassing Eurasia and Africa ). From around 19th century onward, due to
