Say Department

To the west of these rapids lies what is now the W Regional Park, a sparsely populated area historically plagued by insect borne diseases of both humans and cattle.

Now a park and tourist attraction, its history as a "no mans land" has made it a refuge for remaining wild animals, as well as several undisturbed archeological sites.

The inhabitants at the time were related to the Gourma people, who form most of the population of the northwestern part of the Department today.

In the 18th and 19th century, the town of Say was founded by Fulani migrants from the Gao region of modern Mali, with others expanding from what is now northeast Burkina Faso.

Between 1810 and the arrival of European writer Heinrich Barth in 1854, Fulani Muslims led by Alfa Mohamed Diobo of Djenné had established the Emirate of Say.
