Ghana is a multiethnic country rich in natural resources and is one of the most stable and democratic countries in West Africa. Ghana has been inhabited for at least several thousand years, however, little is known about its early inhabitants. By the 12th century, the gold trade started to boom in Bono (Bonoman) state in what is today southern Ghana, and it became the genesis of Akan power and wealth in the region. Beginning in the 15th century, the Portuguese, followed by other European powers, arrived and contested for trading rights. Numerous kingdoms and empires emerged in the area, among the most powerful were the Kingdom of Dagbon in the north and the Asante (Ashanti) Empire in the south. By the mid-18th century, Asante was a highly organized state with immense wealth; it provided enslaved people for the Atlantic slave trade, and in return received firearms that facilitated its territorial expansion.
