[6] Situated in the southernmost reaches of the Sahel, Salaga was referred to as "the Timbuktu of the south" for its cosmopolitan population and varied trade.
However, being a cosmopolitan town, Salaga was inhabited by Hausas, Wangaras, Dagombas, Gurmas, and other groups from the region as well as the indigenous Gonja.
Salaga was central to the emergence of the Zabarima (emirate) as a power in the area that is now northern Ghana, when the scholar Alfa Hano and the warrior Gazari migrated here from their former homes south-east of Niamey in the 1860s.
[7] The Salaga market served as a transit point through the northern Sahel and the southernmost coast of the 'Sahel', as well as through the Dagomba towns of Kpabia and Yendi.
In Salaga, there is a pond named "Wonkan bawa," which is a Huasa phrase that means "the bathing spot of slaves."
