Gambia

The territory of present-day Gambia, a narrow strip of land tracing the lower course of the Gambia River, was inhabited from antiquity by peoples ancestral to the Mandinka, Wolof, Fula, Jola, and Serahule, among others. Stone circles at Wassu and Kerbatch, dating roughly from the third century BCE to the sixteenth century CE, attest to organised societies capable of large-scale funerary construction. From the thirteenth century the river basin was drawn into the orbit of the Mali Empire, and local Mandinka polities along its banks paid tribute to Mansa Musa and his successors. As Mali's authority receded after the fifteenth century, smaller riverine kingdoms such as Niumi, Baddibu, Wuli, and Kombo emerged, governed by mansas and sustained by trade in salt, kola, gold, and slaves.

Portuguese navigators, beginning with Alvise Cadamosto in 1455 and Diogo Gomes in 1456, were the first Europeans to chart the river, and Portuguese, then English, French, and Dutch traders established factories along its lower reaches during the sixteenth and seventeenth centuries. The British Crown chartered the Royal Adventurers and later the Royal African Company to conduct trade from forts at James Island and elsewhere, while French interests concentrated downstream of the Senegal River. After repeated Anglo-French contests, the Treaty of Versailles in 1783 confirmed British rights on the Gambia, and in 1816 Captain Alexander Grant founded Bathurst, the modern Banjul, on Banjul Island. The settlement grew as a base for the suppression of the Atlantic slave trade following British abolition in 1807.

Through the nineteenth century the British presence expanded inland in fits and starts, complicated by the Soninke-Marabout Wars between traditional rulers and Muslim reformers that reshaped the river's hinterland. A protectorate over the upriver territories was formally proclaimed in 1894, separate from the colony of Bathurst, and the colony's boundaries were fixed by Anglo-French agreements that left Gambia as an enclave within French Senegal. Colonial administration relied on indirect rule through chiefs, with groundnut cultivation becoming the dominant export. Constitutional reforms after the Second World War widened African participation, and in 1960 a ministerial system was introduced under Chief Minister Pierre Sarr N'Jie, soon succeeded by Dawda Jawara of the People's Progressive Party.

The Gambia gained independence within the Commonwealth on 18 February 1965, with Jawara as prime minister, and became a republic on 24 April 1970 with Jawara as its first president. A 1981 coup attempt by leftist insurgents was suppressed with Senegalese military assistance, prompting the short-lived Senegambia Confederation between the two states from 1982 to 1989. In July 1994 a group of junior officers led by Lieutenant Yahya Jammeh overthrew Jawara, dissolving the constitution; civilian rule was restored under a new constitution in 1996, with Jammeh winning successive presidential elections. His government withdrew the country from the Commonwealth in 2013 and proclaimed an Islamic republic in 2015.

In December 2016 Adama Barrow, leading a coalition of opposition parties, defeated Jammeh at the polls, and after Jammeh refused to concede a regional ECOWAS military intervention secured the transfer of power in January 2017. Barrow rejoined the Commonwealth in 2018 and was re-elected in 2021. The Gambia today is a unitary presidential republic operating under the 1997 constitution, with a directly elected president and a unicameral National Assembly seated in Banjul.
