The history of Dabou is rooted in the pre-colonial era, when the lands on the southeastern coast of modern-day Côte d'Ivoire became home to the Akan peoples. It is believed that the Adjoukrou tribes, who migrated from western regions, played a key role in founding the settlement. They settled in the Lagunes region, drawn by the abundance of local resources and the convenient location by the water.
Geography was the primary factor in the city's development: Dabou emerged at the intersection of water and land routes. The Comoé River, flowing in the immediate vicinity, served as a natural artery connecting the country's interior with the coast of the Gulf of Guinea. This transformed the settlement into an important trading post and a resting place for caravans, where there was an active exchange of salt, gold, kola nuts, and local handicrafts.
The first appearance of Europeans in these parts dates back to the end of the 15th century, when Portuguese explorers began surveying the coast. They were followed by Dutch and Danish traders, attracted by the opportunity to purchase ivory. This early involvement in international trade predetermined Dabou's future role as a significant administrative and economic center during the colonial era.
