114-511: Gars are an ancient group of ray-finned fish in the family Lepisosteidae . They comprise seven living species of fish in two genera that inhabit fresh , brackish , and occasionally marine waters of eastern North America , Central America and Cuba in the Caribbean , though extinct members of the family were more widespread. They are the only surviving members of the Ginglymodi ,
228-422: A proposed referendum on the future of the territory but the deadlock was not broken. Political reforms in the 1990s resulted in the establishment of a bicameral legislature with Morocco's first opposition-led government coming to power. King Hassan II died in 1999 and was succeeded by his son, Mohammed VI . He is a cautious moderniser who has introduced some economic and social liberalisation. Mohammed VI paid
342-415: A caudal fin, and a dorsal fin. The bone structures within the fins are important to study as they can show homology throughout the fossil record. Specifically, the pelvic girdle resembles that of other actinopterygians while still having some of its own characteristics. Gars have a postcleithrun - which is a bone that is lateral to the scapula, but do not have postpectorals. Proximally to the postcleithrum,
456-577: A church. The Muslim conquest of the Maghreb that had begun during the mid-7th century was completed under the Umayyad Caliphate by 709. The caliphate introduced both Islam and the Arabic language to the area; this period also saw the beginning of a trend of Arab migration to the Maghreb which would last for centuries and effect a demographic shift in the region. While constituting part of
570-512: A clade of fish which first appeared during the Triassic , over 240 million years ago, and are one of only two surviving groups of holosteian fish, alongside the bowfins , which have a similar distribution. Gars have elongated bodies that are heavily armored with ganoid scales , and fronted by similarly elongated jaws filled with long, sharp teeth. Gars are sometimes referred to as "garpike", but are not closely related to pike , which are in
684-685: A controversial visit to the Western Sahara in 2002. Morocco unveiled an autonomy blueprint for Western Sahara to the United Nations in 2007. The Polisario rejected the plan and put forward its own proposal. Morocco and the Polisario Front held UN-sponsored talks in New York City but failed to come to any agreement. In 2010, security forces stormed a protest camp in the Western Sahara, triggering violent demonstrations in
798-612: A distinctive Maghrebi ancestry formed from a mixture of Near Eastern and African ancestry, which is still found as a part of the genome of modern Northwest Africans. Later during the Neolithic , from around 7,500 years ago onwards, there was a migration into Northwest Africa of European Neolithic Farmers from the Iberian Peninsula (who had originated in Anatolia several thousand years prior), as well as pastoralists from
912-447: A few, most notably Atractosteus tristoechus , are sometimes found in the sea. Some gars travel from lakes and rivers through sewers to get to ponds. The gar family contains seven extant species, in two genera: A. tropicus A. tristoechus A. spatula [REDACTED] L. oculatus L. platyrhincus L. osseus [REDACTED] L. platostomus [REDACTED] Family Lepisosteidae The largest member of
1026-459: A free-swimming larval stage. However other patterns of ontogeny exist, with one of the commonest being sequential hermaphroditism . In most cases this involves protogyny , fish starting life as females and converting to males at some stage, triggered by some internal or external factor. Protandry , where a fish converts from male to female, is much less common than protogyny. Most families use external rather than internal fertilization . Of
1140-530: A gulp of air. Gar flesh is edible and the hard skin and scales of gars are used by humans, but gar eggs are highly toxic. The name "gar" was originally used for a species of needlefish ( Belone belone ) found in the North Atlantic and likely took its name from the Old English word for "spear". Belone belone is now more commonly referred to as the "garfish" or "gar fish" to avoid confusion with
1254-615: A joint Moroccan-French administration, while creating a modern school system. Several divisions of Moroccan soldiers ( Goumiers or regular troops and officers) served in the French army in both World War I and World War II , and in the Spanish Nationalist Army in the Spanish Civil War and after ( Regulares ). The institution of slavery was abolished in 1925. Between 1921 and 1926, an uprising in

It can reach up to 6 feet and 8 inches in length and weigh up to 35–80 pounds. Like the shortnose gar, it has only a single row of teeth. Unlike its relatives, it enters brackish water from time to time. Females are larger and live longer than
1482-537: A new constitution curbing the powers of the king. In July 2011, the King won a landslide victory in a referendum on a reformed constitution he had proposed to placate the Arab Spring protests. In the first general elections that followed, the moderate Islamist Justice and Development Party won a plurality of seats, with Abdelilah Benkirane being designated as head of government per the new constitution. Despite

Additionally, French and the Moroccan dialect of Arabic are widely spoken. The culture of Morocco is a mix of Arab , Berber , African and European cultures. Its capital is Rabat , while its largest city is Casablanca . The region constituting Morocco has been inhabited since
1710-527: A rapid recovery of freshwater ecosystems. Two short-snouted gar genera, Masillosteus and Cuneatus , are known from the Eocene in western North America and Europe, but disappear shortly afterwards. Lepisosteus and Atractosteus show a similar initial distribution and eventual contraction, but both genera dispersed to eastern North America prior to their disappearance from western North America and Europe, with Atractosteus also dispersing further south to
1824-566: A slower rate after reaching adulthood. They are deep green or yellow in color. Recreational fishing of the alligator gar became popular due to its massive size and its meat is sold for food. Over five decades of overfishing have brought it close to extinction, and man-made dams have contributed to this loss by restricting the gar's access to the flood plain areas in which it spawns. Some U.S. states have enacted laws to combat overfishing, and reintroduction programs are being carried out in some states, such as Illinois , where human activity has extirpated
1938-418: A state of emergency and suspended parliament in 1965. In 1971 and 1972, there were two failed attempts to depose the king and establish a republic. A truth commission set up in 2005 to investigate human rights abuses during his reign confirmed nearly 10,000 cases, ranging from death in detention to forced exile. Some 592 people were recorded killed during Hassan's rule according to the truth commission. In 1963,
2052-566: A strong reaction from the German Empire ; and a crisis loomed in 1905. The matter was resolved at the Algeciras Conference in 1906. The Agadir Crisis of 1911 increased tensions between European powers. The 1912 Treaty of Fez made Morocco a protectorate of France, and triggered the 1912 Fez riots . Spain continued to operate its coastal protectorate. By the same treaty, Spain assumed the role of protecting power over
2166-422: A temperature of 120 degrees Celsius, but as the roe's temperature does not typically reach that level when it is cooked, even cooked roe causes severe symptoms. It was once thought that the production of the toxin in gar roe was an evolutionary adaptation to provide protection for the eggs, but bluegills and channel catfish fed gar eggs in experiments remained healthy, even though they are the natural predators of
2280-742: A trait still present in Holostei ( bowfins and gars ). In some fish like the arapaima , the swim bladder has been modified for breathing air again, and in other lineages it have been completely lost. The teleosts have urinary and reproductive tracts that are fully separated, while the Chondrostei have common urogenital ducts, and partially connected ducts are found in Cladistia and Holostei. Ray-finned fishes have many different types of scales ; but all teleosts have leptoid scales . The outer part of these scales fan out with bony ridges, while
2394-694: A variety of terms denoting the Sharifi heritage of the 'Alawi dynasty , such as al-Mamlakah ash-Sharīfah ( المملكة الشريفة ), al-Iyālah ash-Sharīfah ( الإيالة الشريفة ) and al-Imbarāṭūriyyah ash-Sharīfah ( الإمبراطورية الشريفة ), rendered in French as l'Empire chérifien and in English as the 'Sharifian Empire'. The area of present-day Morocco has been inhabited since at least Paleolithic times , beginning sometime between 190,000 and 90,000 BC. A recent publication has suggested that there

2622-587: Is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called lepidotrichia , as opposed to the bulkier, fleshy lobed fins of the sister class Sarcopterygii (lobe-finned fish). Resembling folding fans , the actinopterygian fins can easily change shape and wetted area , providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to
2736-422: Is a smaller species of gar, measuring just under four feet long and weighing 15 pounds on average. Like Florida gars, female spotted gars are typically larger than male spotted gars. This gar has dark spots covering its head, body, and fins. Its body is compact, and it has a shorter snout. It prefers to live in clearer shallow water with a depth of 3–5 meters, and to surround itself in foliage. Its habitat ranges from
2850-503: Is commonly confused with its cousin, the spotted gar . Uneven black spots cover its head, body, and fins. Green-brown scales run along the back of its body, and the scales on its underbelly are white or yellow. This coloration, which blends well with the gar's surroundings, allows it to ambush its prey. The Florida gar has no ganoid scales on its throat. Female Florida gars grow to lengths between 13 and 34 inches, bigger than their male counterparts. The spotted gar ( Lepisosteus oculatus )
2964-545: Is divided into the infraclasses Holostei and Teleostei . During the Mesozoic ( Triassic , Jurassic , Cretaceous ) and Cenozoic the teleosts in particular diversified widely. As a result, 96% of living fish species are teleosts (40% of all fish species belong to the teleost subgroup Acanthomorpha ), while all other groups of actinopterygians represent depauperate lineages. The classification of ray-finned fishes can be summarized as follows: The cladogram below shows

During the Upper Paleolithic , the Maghreb was more fertile than it is today, resembling a savanna , in contrast to its modern arid landscape. DNA studies of Iberomaurusian peoples at Taforalt , Morocco dating to around 15,000 years ago have found them to have
3192-506: Is found in the Mississippi River Basin , Indiana , Wisconsin , Montana , Alabama , and Louisiana . It prefers to live in lakes, swamps, and calm pools. The shortnose gar takes its name from its snout, which is shorter and broader than that of other gar species. Like the longnose gar , it has one row of teeth. The upper jaw is longer than the rest of its head. The shortnose gar is deep green or brown in color, similar to
3306-432: Is relatively rare and is found in about 6% of living teleost species; male care is far more common than female care. Male territoriality "preadapts" a species for evolving male parental care. There are a few examples of fish that self-fertilise. The mangrove rivulus is an amphibious, simultaneous hermaphrodite, producing both eggs and spawn and having internal fertilisation. This mode of reproduction may be related to

Extant species can range in size from Paedocypris , at 8 mm (0.3 in); to the massive ocean sunfish , at 2,300 kg (5,070 lb); and to the giant oarfish , at 11 m (36 ft). The largest ever known ray-finned fish, the extinct Leedsichthys from the Jurassic , has been estimated to have grown to 16.5 m (54 ft). Ray-finned fishes occur in many variant forms. The main features of typical ray-finned fish are shown in
5700-421: The dorsal fins are close to the tail. As their vascularised swim bladders can function as lungs, most gars surface periodically to take a gulp of air, doing so more frequently in stagnant or warm water when the concentration of oxygen in the water is low. Experiments on the swim bladder has shown that the temperature of the water affects which respiration method the gar will use - aerial or aquatic. They increase

Except from the bichirs , which just like the lungs of lobe-finned fish have retained the ancestral condition of ventral budding from the foregut , the swim bladder in ray-finned fishes derives from a dorsal bud above the foregut. In early forms the swim bladder could still be used for breathing,
7866-553: The aerial breathing rate (breathing air) as the temperature of the water is increased. Gars can live completely submerged in oxygenated water without access to air and remain healthy while also being able to survive in deoxygenated water if allowed access to air. This adaptation can be the result of environmental pressures and behavioral factors. As a result of this organ, they are extremely resilient and able to tolerate conditions that most other fish could not survive. The gar has paired pectoral fins and pelvic fins, as well as an anal fin,

In other parts of the Islamic world, for example in Egyptian and Middle Eastern Arabic literature before the mid-20th century, Morocco was commonly referred to as Murrakush ( مراكش ). The term is still used to refer to Morocco today in several Indo-Iranian languages, including Persian , Urdu , and Punjabi . Morocco has also been referred to politically by
8322-673: The country to this day, seized power in 1631, and over the next two centuries expanded diplomatic and commercial relations with the Western world . Morocco's strategic location near the mouth of the Mediterranean drew renewed European interest; in 1912, France and Spain divided the country into respective protectorates , reserving an international zone in Tangier . Following intermittent riots and revolts against colonial rule, in 1956, Morocco regained its independence and reunified. Since independence, Morocco has remained relatively stable. It has
8436-706: The different actinopterygian clades (in millions of years , mya) are from Near et al., 2012.

8550-660: The end of the Cretaceous. Several different gar genera survived the Cretaceous-Paleogene extinction event , although they remained restricted to North America and Europe after this point. One species ( Atractosteus grandei , a relative of the modern alligator gar ) is the oldest known animal of the Cenozoic , with one fossil specimen dated to just a few thousand years after the Chicxulub impact , indicating
8664-830: The first vowel has been changed, likely influenced by the word "Moor". Historically, the territory has been part of what Muslim geographers referred to as al-Maghrib al-Aqṣā [ ar ] ( المغرب الأقصى , 'the Farthest West [of the Islamic world]' designating roughly the area from Tiaret to the Atlantic ) in contrast with neighbouring regions of al-Maghrib al-Awsaṭ [ ar ] ( المغرب الأوسط , 'the Middle West': Tripoli to Béjaïa ) and al-Maghrib al-Adnā [ ar ] ( المغرب الأدنى , 'the Nearest West': Alexandria to Tripoli ). Morocco's modern Arabic name
8778-437: The fish family Esocidae . All of the gars are relatively large fish, but the alligator gar ( Atractosteus spatula ) is the largest; the alligator gar often grows to a length over 2 m (6.5 ft) and a weight over 45 kg (100 lb), and specimens of up to 3 m (9.8 ft) in length have been reported. Unusually, their vascularised swim bladders can function as lungs, and most gars surface periodically to take
8892-432: The fish's habit of spending long periods out of water in the mangrove forests it inhabits. Males are occasionally produced at temperatures below 19 °C (66 °F) and can fertilise eggs that are then spawned by the female. This maintains genetic variability in a species that is otherwise highly inbred. Actinopterygii is divided into the subclasses Cladistia , Chondrostei and Neopterygii . The Neopterygii , in turn,
9006-444: The force of law, and can also dissolve the parliament after consulting the prime minister and the president of the constitutional court. Morocco claims ownership of the non-self-governing territory of Western Sahara , which it has designated its Southern Provinces . In 1975, after Spain agreed to decolonise the territory and cede its control to Morocco and Mauritania , a guerrilla war broke out between those powers and some of
9120-469: The gar eggs. Crayfish fed the roe were not immune to the toxin, and most died. The roe's toxicities to humans and crayfish may be coincidences, however, and not the result of explicit natural selection. Several species are traded as aquarium fish. The hard ganoid scales of gars are sometimes used to make jewelry whereas the tough skin is used to make such items as lamp shades. Historically, Native Americans used gar scales as arrowheads, native Caribbeans used
9234-692: The gar family, the alligator gar ( Atractosteus spatula ), can measure up to 10 feet long and weigh over 300 pounds. Its body and snout are wide and stocky, and it was named "alligator gar" because locals often mistook it for an alligator . The species can be found in Texas , Oklahoma , Louisiana , the Mississippi River , Ohio , the Missouri river , and the southern drainages into Mexico . Its habitat consists of lakes and bays with slow currents. The gars grow rapidly when young and continue to grow at
9348-443: The gar. Before being released, each gar must meet a length requirement to ensure that it has the best chance of survival in the wild. Some states, such as Texas , restrict the number of gar that may be caught in a day, the season in which they may be caught, and the equipment anglers may use to catch them. Some states also impose a minimum length requirement to prevent gar from being caught at too early an age. Scientists have found that
9462-661: The gars and bowfin together forming the clade Holostei ; both lineages diverged during the Late Permian . The closest extinct relatives of gar are the Obaichthyidae , an extinct group of gar-like fishes from the Early Cretaceous of Africa and South America, which likely diverged from the ancestors of true gars during the Late Jurassic . The oldest anatomically modern gar is Nhanulepisosteus from
9576-671: The gars in North America lies mainly in the shallow, brackish waters off of Texas, Louisiana, and the eastern coast of Mexico, as well as in some of the rivers and lakes that flow into them. A few populations are also present in the Great Lakes region of the United States, living in similar shallow waters. Gar bodies are elongated, heavily armored with ganoid scales , and fronted by similarly elongated jaws filled with long, sharp teeth. Their tails are heterocercal , and
9690-605: The illegal migrants to Morocco from Melilla. In 2006, the Spanish Premier Zapatero visited Spanish enclaves. He was the first Spanish leader in 25 years to make an official visit to the territories. The following year, Spanish King Juan Carlos I visited Ceuta and Melilla, further angering Morocco which demanded control of the enclaves. During the 2011–2012 Moroccan protests , thousands of people rallied in Rabat and other cities calling for political reform and
9804-438: The inner part is crossed with fibrous connective tissue. Leptoid scales are thinner and more transparent than other types of scales, and lack the hardened enamel - or dentine -like layers found in the scales of many other fish. Unlike ganoid scales , which are found in non-teleost actinopterygians, new scales are added in concentric layers as the fish grows. Teleosts and chondrosteans (sturgeons and paddlefish) also differ from
9918-473: The kingdom was smaller than previous ones in the region, it remained quite wealthy. Against the opposition of local tribes Ismail Ibn Sharif (1672–1727) began to create a unified state. With his Riffian army, he re-occupied Tangier from the English who had abandoned it in 1684 and drove the Spanish from Larache in 1689. The Portuguese abandoned Mazagão , their last territory in Morocco, in 1769. However,
10032-530: The larger empire, Morocco was initially organised as a subsidiary province of Ifriqiya , with the local governors appointed by the Muslim governor in Kairouan . The indigenous Berber tribes adopted Islam, but retained their customary laws . They also paid taxes and tribute to the new Muslim administration. The first independent Muslim state in the area of modern Morocco was the Kingdom of Nekor , an emirate in
10146-903: The late 3rd century, direct Roman rule had become confined to a few coastal cities, such as Septum ( Ceuta ) in Mauretania Tingitana and Cherchell in Mauretania Caesariensis . When, in 429 AD, the area was devastated by the Vandals , the Roman Empire lost its remaining possessions in Mauretania, and local Mauro-Roman kings assumed control of them. In the 530s, the Eastern Roman Empire , under Byzantine control, re-established direct imperial rule of Septum and Tingi , fortified Tingis and erected
10260-466: The main clades of living actinopterygians and their evolutionary relationships to other extant groups of fishes and the four-limbed vertebrates ( tetrapods ). The latter include mostly terrestrial species but also groups that became secondarily aquatic (e.g. whales and dolphins ). Tetrapods evolved from a group of bony fish during the Devonian period . Approximate divergence dates for
10374-451: The male longnose gar. Females live 22 years, and males about half as long. There are spots on the head, dorsal , anal , and caudal fins . Depending on the water clarity , the longnose gar comes in two colors. In clear water, they're a dark deep green color. In muddy waters, it is more brown in color. Edges of the ganoid scales and in between are black. These types of gar are occasionally fished by locals, and blamed for eating other fish in
10488-605: The modern state of Mauritania ) flourished around 225 BC or earlier. Mauretania became a client kingdom of the Roman Empire in 33 BC. Emperor Claudius annexed Mauretania directly in 44 AD, making it a Roman province ruled by an imperial governor (either a procurator Augusti , or a legatus Augusti pro praetore ). During the Crisis of the Third Century , parts of Mauretania were reconquered by Berbers. By
10602-561: The most substantial of which were Chellah , Lixus , and Mogador . Mogador was established as a Phoenician colony as early as the 6th century BC. Morocco later became a realm of the Northwest African civilisation of ancient Carthage , and part of the Carthaginian empire. The earliest known independent Moroccan state was the Berber kingdom of Mauretania , under King Baga . This ancient kingdom (not to be confused with
10716-472: The north-west to the north-east. The Atlas Mountains run down the backbone of the country, from the northeast to the southwest. Most of the southeast portion of the country is in the Sahara Desert and as such is generally sparsely populated and unproductive economically. Most of the population lives to the north of these mountains, while to the south lies the Western Sahara, a former Spanish colony that
10830-436: The northern and central mountains, giving way to steppe, semi-arid and desert areas in the eastern and southern regions. The Moroccan coastal plains experience moderate temperatures even in summer. In the Rif, Middle and High Atlas Mountains, there exist several different types of climates: Mediterranean along the coastal lowlands, giving way to a humid temperate climate at higher elevations with sufficient moisture to allow for
10944-606: The northern coastal and southern Saharan zones. Tens of thousands of colonists entered Morocco. Some bought up large amounts of rich agricultural land, while others organised the exploitation and modernisation of mines and harbours. Interest groups that formed among these elements continually pressured France to increase its control over Morocco – with some Moroccan tribes allying with the French against other competing tribes from early on in its conquest. The French colonial administrator, Governor general Marshal Hubert Lyautey , sincerely admired Moroccan culture and succeeded in imposing
11058-470: The only surviving members of the Ginglymodi , a group of bony fish that flourished in the Mesozoic . The oldest known ginglymodians appeared during the Middle Triassic , over 240 million years ago. Because they have the slowest known rate of molecular evolution among all jawed vertebrates, it has also slowed down their rate of speciation. The closest living relatives of gars are the bowfin , with
11172-426: The protection of the sultanate and could thus enjoy safe passage. The 1786 Moroccan–American Treaty of Friendship stands as the United States' oldest unbroken friendship treaty. As Europe industrialised, Northwest Africa was increasingly prized for its potential for colonisation. France showed a strong interest in Morocco as early as 1830, not only to protect the border of its Algerian territory, but also because of
11286-494: The proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts . By species count, they dominate the subphylum Vertebrata , and constitute nearly 99% of the over 30,000 extant species of fish . They are the most abundant nektonic aquatic animals and are ubiquitous throughout freshwater and marine environments from
11400-480: The quake was around 70 km southwest of city of Marrakech. Morocco has a coast by the Atlantic Ocean that reaches past the Strait of Gibraltar into the Mediterranean Sea . It is bordered by Spain to the north (a water border through the Strait and land borders with three small Spanish-controlled exclaves , Ceuta , Melilla , and Peñón de Vélez de la Gomera ), Algeria to the east, and Western Sahara to
11514-512: The reforms made by Mohammed VI, demonstrators continued to call for deeper reforms. Hundreds took part in a trade union rally in Casablanca in May 2012. Participants accused the government of failing to deliver on reforms. On 10 December 2020, Israel–Morocco normalisation agreement was announced and Morocco announced its intention to resume diplomatic relations with Israel. Joint Declaration of
11628-431: The regional capital El Aaiún . In 2002, Morocco and Spain agreed to a US-brokered resolution over the disputed island of Perejil . Spanish troops had taken the normally uninhabited island after Moroccan soldiers landed on it and set up tents and a flag. There were renewed tensions in 2005, as dozens of African migrants stormed the borders of the Spanish enclaves of Melilla and Ceuta. In response, Spain deported dozens of
11742-581: The rivers. The longnose gar has a large range of territory in North America , into the Gulf of Mexico . Located in Florida , Quebec , all Great Lakes except Lake Superior , Missouri , Mississippi , Texas , and northern Mexico . The flesh of gar is edible, but its eggs contain an ichthyotoxin , a type of protein toxin which is highly toxic to humans. The protein can be denatured when brought to
11856-449: The shallow and weedy areas of rivers, lakes, and bayous , often congregating in small groups. They are voracious predators, catching their prey in their needle-like teeth with a sideways strike of the head. They feed extensively on smaller fish and invertebrates such as crabs. Gars are found across much of the eastern portion of North America. Although gars are found primarily in freshwater habitats, several species enter brackish waters and
11970-845: The skin for breastplates, and early American pioneers covered the blades of their plows with gar skin. It is suspected that gars have an unusually strong DNA repair apparatus. If confirmed by further studies, it could be used in medical treatments against human diseases like cancer. Not much is known about the precise function of the gar in Native American religion and culture other than the ritual "garfish dances" that have been performed by Creek and Chickasaw tribes. Ray-finned fish Actinopterygii ( / ˌ æ k t ɪ n ɒ p t ə ˈ r ɪ dʒ i aɪ / ; from actino- 'having rays' and Ancient Greek πτέρυξ (ptérux) 'wing, fins'), members of which are known as ray-finned fish or actinopterygians ,
12084-609: The south. Since Morocco controls most of Western Sahara, its de facto southern boundary is with Mauritania . The internationally recognised borders of the country lie between latitudes 27° and 36°N, and longitudes 1° and 14°W . The geography of Morocco spans from the Atlantic Ocean, to mountainous areas, to the Sahara desert. Morocco is a Northern African country, bordering the North Atlantic Ocean and
12198-525: The strategic position of Morocco with coasts on the Mediterranean and the open Atlantic. In 1860, a dispute over Spain's Ceuta enclave led Spain to declare war. Victorious Spain won a further enclave and an enlarged Ceuta in the settlement. In 1884, Spain created a protectorate in the coastal areas of Morocco. In 1904, France and Spain carved out zones of influence in Morocco. Recognition by the United Kingdom of France's sphere of influence provoked
12312-423: The supracleithrum is important as it plays a critical role in opening the gar's jaws. This structure has a unique internal coracoid lamina only present in the gar species. Near the supracleithrum is the posttemporal bone, which is significantly smaller than other actinopterygians. Gars also have no clavicle bone, although elongated plates have been observed within the area. All the gars are relatively large fish, but
12426-572: The territories across the Sahara proved too difficult. Upon the death of al-Mansur, the country was divided among his sons. After a period of political fragmentation and conflict during the decline of the Saadi dynasty, Morocco was finally reunited by the Alawi sultan al-Rashid in the late 1660s, who took Fez in 1666 and Marrakesh in 1668. The 'Alawis succeeded in stabilising their position, and while
12540-499: The territory. Moroccan and Algerian troops soon clashed in Western Sahara . Morocco and Mauritania divided up Western Sahara. Fighting between the Moroccan military and Polisario forces continued for many years. The prolonged war was a considerable financial drain on Morocco. In 1983, Hassan cancelled planned elections amid political unrest and economic crisis. In 1984, Morocco left the Organisation of African Unity in protest at
12654-468: The unpopular Mohammed Ben Aarafa sparked active opposition to the French and Spanish protectorates. The most notable violence occurred in Oujda where Moroccans attacked French and other European residents in the streets. France allowed Mohammed V to return in 1955, and the negotiations that led to Moroccan independence began the following year. In March 1956 Morocco regained its independence from France as
