evidence: Sipilou is a town in the Tonkpi Region in the Mountain District. It is a border town located in the West of Côte d'Ivoire, 6 km from Guinea, 65 km from the Department of Biankouman and 700 km from Abidjan. [...] The people of Sipilou of the Yacouba ethnic group belong to the Dan group. They are said to have come from neighbouring Guinea and Liberia. The authentic name of Sipilou is Sikpipleu in the Yacouba language, which means "the village of Sikpi" who was the founder. By transformation Sikpipleu becomes Sipilou. This locality was conquered by the emperor Samory Touré and his Sofa from Guinea. Samory Touré spent several months there, creating an inter-ethnic mix between the inhabitants of Guinea and those of Sipilou. Some of the Yacouba of Sipilou have relatives in Guinea known by the ethnic name Cônon. [...] Sipilou has been the chief town of a commune since 17 October 1985 and the chief town of a department since July 2012.
