The Gambia cuts deep into Senegal

On the map Senegal is not a smooth block on the West African coast. The Gambia, a state of its own along the Gambia River, pushes in from the Atlantic and leaves Senegalese land to the north and the south. Casamance, in the south, is therefore not a detached piece, and it is not an obvious annex of Dakar either. Anyone going there from the capital skirts the corridor to the east or crosses Gambian ground.

Dakar stands on the Cap-Vert peninsula, on the western edge of the African mainland. The Senegal River in the north is the border with Mauritania. Mali lies to the east, Guinea and Guinea-Bissau to the south, and the Gambian notch occupies the middle of the western flank. On 196,722 square kilometres live 18,931,966 people. The figure describes a mid-sized country. The shape describes a country whose interior is co-written by a neighbour.

A corridor, not a gap

The Gambia does not reach Senegal's eastern border. East of the corridor, Senegalese land remains, and through it the north stays joined to Casamance. That is the decisive sentence of the map. Look only at the Gambia's narrow shape and Senegal seems cut in two. Read the east as well and you see a state that reaches around a river neighbour. Ziguinchor, the city of Casamance, belongs to Senegal. The short road there from Dakar still crosses a border.

The notch is political, not only a line on paper. A north-south journey in the west is a journey through another state, with its own border, its own currency and its own law. The long way round to the east stays on Senegalese soil and costs distance. Dakar governs both sides. Geography reminds the government, on every road, that the sides do not flow freely into each other. Senegal is continuous, and it is still built around a neighbour.

The Gambia is not a hole in Senegal. It is a corridor, and the road has to take it seriously.

Dakar on the western edge

The capital does not sit at the geometric middle, and it does not sit in Casamance. It sits on Cap-Vert, a peninsula that points west into the Atlantic. The port, the administration and the country's largest urban space are thus on the outermost edge, turned toward the sea and away from the long east. From here Mali is hinterland. From here Casamance is a question of route. The peninsula makes Dakar easy to find and turns the rest of the country into distance.

In the north the Senegal River orders the border with Mauritania. The capital is not on that river. It is on the sea, south of the river mouth, on the peninsula. Senegal thus has two strong lines that do not coincide: the river as the northern border, and the peninsula as the seat of the state. Between them and behind them lies the country that the Gambian corridor organises. The capital faces the sea. The territory faces a neighbour in its flank.

French in office, Wolof in the street

The constitution makes French the official language. The same constitution names national languages, among them Wolof, Pular, Serer, Diola, Mandinka and Soninke. Wolof is the language in which a large part of the country speaks beyond its own community of origin. The office stays French, and the banknote stays the West African CFA franc of the BCEAO. The state is thus linguistically on two floors: an official language for the law, a common language for the day, and further languages that carry regions.

This language order does not change the map of the corridor. It only shows what the state governs across. Dakar, Casamance and the eastern link share the French of the office and do not automatically share the same everyday speech. Casamance has languages of its own and a location of its own, south of The Gambia. It stays Senegalese because the territory is continuous and because the law holds it so.

Senegal does not end at The Gambia, and it does not ignore The Gambia either. The state reaches around the river corridor, the capital stays on Cap-Vert, and Casamance stays reachable if the route is part of the thought. The shape is the thesis.
