Katiola
Katiola lay in the Tagbana country of the northern Ivorian interior, south of the commercial centre of Kong. The Tagbana formed part of the wider Senufo world, but their communities had distinct settlement traditions. Accounts of their origins recall successive migrations, meetings with earlier inhabitants and the founding of villages, rather than the expansion of a single kingdom over empty land.
Historians tracing these movements place an important route through Kong and Nanguinkaha. In the settlement traditions, Gnèkèrè Silué led a group onwards to found Gnèkèrèkaha; some companions continued farther south into the country where Katiola developed. These movements are associated with the formation of the Tagbana region between the later medieval period and the early nineteenth century. From the eighteenth century, the arrival of Baoulé groups to the south added new neighbours and pressures on settlement. Tagbana landholding communities and Mangoro pottery specialists shared the Katiola area, linking cultivation with craft production. Its early history thus belongs to overlapping village territories and remembered migrations, with Kong providing a northern connection rather than a sufficient account of every community's political allegiance.
