Colonial period
The Western Sahel fell to France in the late 19th century as part of French West Africa. Chad was added in 1900 as part of French Equatorial Africa. The French territories were decolonized in 1960.
The Eastern Sahel (the part in what is now Sudan) did not fall to the European powers but was annexed by Muhammad Ali of Egypt in 1820. It came under British administration as part of the Sultanate of Egypt in 1914. The Sudanese Sahel became part of independent Sudan in 1956, and South Sudan in turn achieved its independence from Sudan proper in 2011.
