Gambia

The lower and middle reaches of the Gambia River hold one of the great concentrations of megalithic monuments in Africa: the Senegambian stone circles. Spread in a band roughly 100 kilometres wide along some 350 kilometres of the river and its hinterland, straddling the modern Gambia–Senegal frontier, they comprise over a thousand stone circles of cut laterite pillars and their associated burial mounds, or tumuli. The pillars were quarried with iron tools and stand on average about two metres high; the tallest, at Wassu in The Gambia, reaches 2.59 metres. Excavated burials have yielded dates broadly between the third century BCE and the sixteenth century CE, with mounds near Wassu dated to roughly the tenth to fourteenth centuries CE.

Together the circles and mounds form a vast sacred landscape, built and reused over more than 1,500 years, that archaeologists read as the work of a settled, prosperous and highly organised society. Scholars have not reached consensus on exactly which people raised them, but the monuments clearly predate the present Mandinka inhabitants of the region. Four representative groups — Wassu and Kerr Batch (Kerbatch) in The Gambia, and Sine Ngayène and Wanar in Senegal — were inscribed together on the UNESCO World Heritage List in 2006 as the Stone Circles of Senegambia, one of only a few trans-boundary World Heritage properties in Africa.

By the time the circles fell out of use, the Senegambian region was home to the ancestors of its principal modern peoples: the Mandinka (Malinke), the Wolof, the Fula (Fulani) and the Serer, among others such as the Jola. Their settlement of the river valley and the surrounding savanna unfolded over centuries through migration and the spread of farming, herding and trade, and it set the human stage on which the medieval West African empires and the river kingdoms would later rise.

From the thirteenth century the Gambia River valley fell within the western sphere of the Mali Empire, the great Mande state that rose under Sundiata Keita and at its height dominated much of West Africa, carrying Islam, long-distance trade and a sophisticated administration across the savanna. Mandinka (Malinke) traders and warriors, expanding from the empire's heartland on the upper Niger, settled the banks of the Gambia and established a patchwork of small kingdoms that paid tribute to, or drew their legitimacy from, the wider Mande world.

Several of these riverine states endured for centuries. Niumi, also called Barra, lay at the mouth of the river on its north bank, extending some 60 kilometres along and inland from the coast; its Mandinka ruling clans grew wealthy by taxing traffic on the river and levying tolls on the European ships that later came to trade. Upstream lay other Mandinka kingdoms such as Niani and Wuli, the latter controlling routes that linked the upper Niger valley to the coast. Alongside the Mandinka, the Wolof, Fula and Serer formed their own polities and communities across Senegambia, in a mosaic of states bound together by trade, kinship and a common riverine economy.

The Gambia River itself was the organising feature of this world — navigable far inland, it served as a highway for salt, kola, ivory, gold, cloth and captives moving between the interior and the coast. Control of crossing points, landing places and stretches of bank translated directly into power and revenue, a logic that would shape the kingdoms' dealings with the European traders who began to arrive in the mid-fifteenth century.

In 1455–1456 ships sailing for Portugal's Prince Henry the Navigator, under the Venetian Alvise Cadamosto and the Genoese Antoniotto Usodimare, entered the Gambia River — the first recorded European voyage there. The Portuguese established trading contacts and small settlements such as San Domingo, and gave the midstream island near the river mouth its first European name. The river's deep, navigable channel made it exceptionally valuable to Europeans, allowing seagoing ships to penetrate far inland to trade for gold, ivory, beeswax, hides and, increasingly, enslaved people.

From the mid-seventeenth century the island at the centre of the river changed hands repeatedly. Settled briefly by the Duchy of Courland, it was taken by the English in 1661, who renamed it James Island and built Fort James, named for James, Duke of York. Chartered English companies — the Royal Adventurers and then the Royal African Company — ran the fort, and the trade shifted decisively toward human beings. France and England struggled over the river for more than a century; the fort was captured several times, and between 1765 and 1783 the Gambia formed part of the British colony of Senegambia. James Island, with the nearby villages of Juffure and Albreda, became one of the most important slaving stations on the river, a place where captives from the interior were held before being shipped across the Atlantic.

This was a catastrophe of immense and lasting human cost. James Island and its related sites — including Juffure, Albreda and the ruined Portuguese chapel and warehouses — were inscribed on the UNESCO World Heritage List in 2003 as a memorial to the slave trade and its eventual abolition; the island was renamed Kunta Kinteh Island in 2011. The name recalls the central figure of Alex Haley's 1976 book Roots, in which Haley traced his ancestry to a man he called Kunta Kinte, said to have been taken from the Juffure area and carried to Maryland in the eighteenth century. Haley's account is a work of family memory and historical fiction whose specific genealogical claims scholars have questioned; the island and Juffure remain, factually, an enduring site of memory of the Atlantic trade. Britain abolished its own slave trade in 1807 and afterward built fortifications such as Fort Bullen at the river mouth to help suppress the traffic it had once carried.

British involvement on the river hardened in the nineteenth century. In 1816 Captain Alexander Grant founded Bathurst (modern Banjul) on St Mary's Island near the river mouth, after an agreement with the local ruler of Kombo; the settlement became Britain's administrative base for suppressing the slave trade and for commerce in the new staple, groundnuts (peanuts). Over the following decades Britain extended its authority up the river through treaties and force, while the older Mandinka kingdoms such as Niumi were drawn into its orbit and finally absorbed.

The Gambia's distinctive shape was the product of imperial bargaining between Britain and France, which was meanwhile building the vast colony of Senegal all around it. A series of Anglo-French boundary agreements in the 1880s and 1890s fixed the frontier as a narrow band following the river, leaving The Gambia almost entirely enclosed by French territory — a colonial accident that has defined the country ever since. By 1902 Britain governed the territory as two units: the small Colony of the Gambia, centred on Bathurst, and the much larger Protectorate of the inland districts, ruled indirectly through local chiefs.

For most of the colonial period The Gambia was a quiet, lightly developed possession whose economy rested overwhelmingly on groundnut exports. Constitutional change came slowly after the Second World War. A new constitution in 1960 created a House of Representatives, and following elections Dawda Jawara — a British-trained veterinary surgeon who led the Protectorate-based People's Progressive Party — became the dominant political figure, serving as premier from 1962 and steering the colony through internal self-government toward full independence.

   After a new 1960 constitution created a House of Representatives, Dawda Jawara of the People's Progressive Party became premier in 1962, leading the colony through internal self-government toward independence.

   [1] [12] [9]

On 18 February 1965 The Gambia became independent within the Commonwealth, at first as a constitutional monarchy with Elizabeth II as queen and Dawda Jawara as prime minister. Many observers doubted that so small and narrow a country, dependent on a single crop and almost surrounded by Senegal, could survive as a separate state, but it did. After an earlier referendum failed to reach the required majority, a second succeeded, and on 24 April 1970 The Gambia became a republic, with Jawara as its first president.

Sir Dawda Kairaba Jawara went on to lead the country for nearly three decades, and his rule was, by the standards of the era, notably moderate: he maintained a multi-party system and avoided the worst authoritarian excesses seen elsewhere in the region, even as his People's Progressive Party dominated successive elections. In 1981, while Jawara was abroad, a violent coup attempt led by Kukoi Samba Sanyang briefly seized Bathurst; Jawara invoked a mutual-defence agreement and Senegalese troops intervened to crush the revolt and restore him, at considerable loss of life.

The 1981 crisis drew The Gambia and Senegal closer. On 1 February 1982, under a treaty signed the previous December, the two countries formed the Senegambia Confederation, intended to integrate their armed forces, security, economies and currencies while each retained its sovereignty; Senegal's President Abdou Diouf served as confederation president and Jawara as vice-president. The union never won broad popular enthusiasm, and disputes over economic integration — particularly Senegal's wish to end The Gambia's lucrative re-export trade — undermined it. After Senegal withdrew its troops in 1989, the confederation was formally dissolved on 30 September 1989, and the two states resumed fully separate paths.

Figures of the era

On 22 July 1994 a group of young army officers led by Lieutenant Yahya Jammeh overthrew Dawda Jawara in a bloodless coup, ending the only government independent Gambia had known. Jammeh, who chaired a military council before contriving a transition to civilian rule, was declared the winner of a presidential election in 1996 and was sworn in as president that November. He went on to win further contests in 2001, 2006 and 2011 and held power for 22 years.

Jammeh's long rule grew steadily more authoritarian and repressive. His government suppressed the press, detained and tortured opponents, and was implicated in enforced disappearances and extrajudicial killings; he made notorious threats against perceived enemies and minorities and, in 2009, presided over a widely condemned witch-hunting campaign. A Truth, Reconciliation and Reparations Commission later documented a pattern of grave human-rights abuses across his presidency. In 2013 Jammeh withdrew The Gambia from the Commonwealth and in 2015 declared it an Islamic republic.

The presidential election of 1 December 2016 produced an upset: Adama Barrow, a real-estate businessman backed by an opposition coalition, defeated Jammeh. Jammeh at first conceded but reversed himself a week later and rejected the result, triggering a constitutional crisis. Barrow was inaugurated at the Gambian embassy in Dakar on 19 January 2017, and the regional bloc ECOWAS, with United Nations authorisation, deployed troops to enforce the outcome. Under that pressure Jammeh agreed to step down and went into exile in Equatorial Guinea on 21 January 2017; Barrow returned to take office at home days later. The Gambia subsequently rejoined the Commonwealth in 2018 and embarked on a process of democratic and institutional reform, with Barrow re-elected in 2021.
