Flags of West Africa

Sixteen countries, and some of the deepest pre-colonial history in the whole atlas. This stretch of coast and savanna held major, well-documented empires centuries before Europeans arrived in force: the Mali Empire under Mansa Musa (whose 1324 pilgrimage to Mecca, with a gold-laden caravan, is still the standard by which historians measure medieval wealth), the Songhai Empire that succeeded it and briefly controlled the Niger Bend's trade routes and scholarly centers like Timbuktu, the Asante Empire in the forest zone, the bronze-casting Benin Empire on the Guinea coast, the Oyo Empire's Yoruba cavalry state, and the Kanem-Bornu sultanate that endured for close to a thousand years around Lake Chad.

European contact began with Portuguese traders in the 1400s and hardened into full colonial rule after the 1884–85 Berlin Conference: France took the largest share (the federation of French West Africa), Britain held Nigeria, Ghana (the Gold Coast), Sierra Leone, and the Gambia, and Portugal held Guinea-Bissau and Cape Verde. Nearly all sixteen reached independence in the same tight window, 1957 to 1975 — Ghana first among them, Guinea-Bissau and Cape Verde last, after armed independence struggles. Each country below is a placeholder for now; a deep dive with its own flag lineage is coming, and the interactive map below already traces all fifteen mainland countries in the meantime.

The 16 countries

Eight centuries, one map

A real, traced map — actual coastlines and borders pulled from real geographic boundary data, not schematic shapes — covering all fifteen mainland countries below (Cape Verde is a mid-Atlantic island group roughly 600–900 km offshore; it doesn't fit this map's frame at any useful scale, so it's tracked in prose only, here and on its own page). Drag the slider or press play; each snapshot simplifies a messier reality into the dominant power of the moment. Cameroon, Chad, Algeria, Western Sahara, and Libya appear faint at the edges for context only — they're not part of this atlas's West African set.

Borders here are data, not decoration. A line between two countries only draws solid when they were actually governed separately that era. When several were ruled by the same crown or the same colonial administration — French West Africa's eight federated colonies from 1904 to 1960, say — every line between them dissolves and their names merge into whoever actually ruled them all. Colors blend between eras instead of jump-cutting.

One correction worth sitting with: the Ghana Empire on the first frame below is not modern Ghana. It was centered hundreds of miles northwest, in what's now southeastern Mauritania and western Mali — modern Ghana takes its name from it by choice, at independence in 1957, as a tribute rather than a claim of direct descent. Watch the color sit over Mauritania and Mali, not over the country actually named Ghana on this map.

Early West African states

Real traced borders (simplified to each country's outer boundary; enclaves and river-island detail are smoothed out). Cape Verde, an Atlantic archipelago with no shared land border, is excluded from the map itself but included throughout the country grid above and its own flag page.

Try: drag slowly from c. 1350 to c. 1500 and watch Senegal, the Gambia, and Guinea-Bissau peel away from the Mali Empire's color into their own separate Jolof and Kaabu colors as Mali's grip loosens — while Mali, Niger, Burkina Faso, and Guinea itself simply change from the Mali color to the Songhai color together, since one empire's successor absorbed the same core territory rather than splitting it. Then jump to 1900: every line among Senegal, Mali, Guinea, Côte d'Ivoire, Burkina Faso, Niger, Mauritania, and Benin disappears at once — eight colonies, one federation, one Governor-General in Dakar — while the British, Portuguese, and German holdings each keep their own separate color the entire time, never part of that federation. Finally at 1960, watch all twenty-seven possible lines on this map snap solid simultaneously: fifteen fully independent countries, for the first time in centuries none of them answering to any of the others or to Paris, London, or Lisbon.

About this hub

This hub now carries the atlas's full interactive map — the same real-coastline, era-slider visualization the Former Yugoslavia and German Lands hubs use, extended here to fifteen mainland countries across eight snapshots spanning roughly a thousand years, from the Ghana Empire to today. Cape Verde sits outside the map's frame for geographic reasons (see above) but keeps its full place in the country grid.

Colors in the country grid above are drawn from each country's current national flag, not a historical palette, since no per-country flag lineage exists yet for most of these sixteen; the map's own historical colors are assigned per era instead, as with every other hub. Full deep-dive flag pages for each country remain a later phase of this project.
