The Gambia is a very small and narrow country with the border based on the Gambia River.
 The country is less than 48 km wide at its greatest width.
 The country's present boundaries were defined in 1889 after an agreement between the United Kingdom and France.
 It is often claimed by Gambians that the distance of the borders from the Gambia River corresponds to the area that British naval cannon of the time could reach from the river's channel.
 However, there is no historical evidence to support the story, and the border was actually delineated using careful surveying methods by the Franco-British boundary commission.
 Apart from its coastline, where the Gambia borders the Atlantic Ocean, it is an enclave of Senegal and is by far the smallest country on mainland Africa.

An administrative division, unit, entity, area or region, also referred to as a subnational entity, constituent unit, or country subdivision, is a portion of a country or other region delineated for the purpose of administration.
 Administrative divisions are granted a certain degree of autonomy and are usually required to manage themselves through their own local governments. Countries are divided up into these smaller units to make managing their land and the affairs of their people easier.
 A country may be divided into provinces, which, in turn, are divided into counties, which, in turn, may be divided in whole or in part into municipalities.
