The name 'Ghana' originally belonged to the ancient Wagadu empire of the western Sudan — a kingdom renowned, from at least the 9th century, for its rulers' wealth in gold, the opulence of their courts, and their mastery of the trans-Saharan gold trade. Arab geographers such as Al Yaqubi described it as one of the three most organized states in the region. The empire declined under pressure from neighbours in the 11th century, but its name and reputation endured.

Within the boundaries of modern Ghana, state-building took a different form. The Mole-Dagbon kingdoms — founded by Naa Gbewaa — are among the earliest political kingdoms, giving rise to Dagbon, Mamprugu and Nanung across the north. The Kingdom of Dagbon resisted enslavement and colonisation fiercely, preferring commodity trade, and was shaped by Islam through contact with neighbouring trading kingdoms.

In the forest belt to the south, Akan-speaking peoples consolidated a network of gold-rich states along the trade routes to the goldfields. The arrival of new crops — sorghum, bananas, cassava — that could thrive under forest conditions spurred settlement and the growth of powerful states such as Bonoman and, later, the Ashanti Empire, which by the 18th century had become the dominant force in the interior under the Golden Stool.
