Made for a contest on r/imaginarymaps

My submission for the current 'Dominions' contest, the Dominion of British Guinea, a federated dominion of British colonies from the border with French Côte D'Ivoire to the Niger river.

Not a specific timeline here. My headcanon is that Britain mostly stayed out of the equivalent European 'world wars', concentrating on consolidating the empire, while still managing to take Benin and Togo to connect their colonies in Nigeria to Ghana. By the mid 20th century, they have begun consolidating many colonies around the world into 'Dominions', similar to those like Canada and Australia.
