Upper Senegal and Niger

Upper Senegal and Niger, or Haut-Sénégale et Niger, was the region that included French Sudan (now Mali), what is now Upper Volta and what is now all of Niger, plus a few little pieces removed or detached. It was once part of the colony of Senegambia and Niger. This was all due to a bureaucratic reshuffling in 1904 of French African colonies, that would make mapmakers busy for the time being.
