There is archaeological evidence showing that humans have lived in present-day Ghana since the Bronze Age. However, until the 11th century, the majority of modern Ghana's area was largely unoccupied. Although the area of present-day Ghana has experienced many population movements, the major ethnic groups in Ghana today were firmly settled by the 16th century. By the early 11th century, the Akan were firmly established in a state called Bonoman, for which the Brong-Ahafo Region region is named. The Ga and Dagomba states were established by the 16th century.
From the 13th century, numerous groups emerged from what is believed to have been the Bonoman area, to create several Akan States, mainly based on gold trading. These states included Denkyira, Akwamu, and Akyem. By the 19th century, most of modern Ghanaian territory was included in the Empire of Ashanti, one of the most influential states in sub-Saharan Africa prior to colonial rule. The Ashanti government operated first as a loose network, and eventually as a centralized kingdom with an advanced, highly specialized bureaucracy centred in Kumasi. It is said that at its peak, the Asantehene could field 500,000 troops, and it had some degree of military influence over all of its neighbours.
Early European contact by the Portuguese, who came to Ghana in the 15th century, focused on the extensive availability of gold. The Portuguese first landed at a coastal city inhabited by the Fante nation-state, and named the place Elmina. In 1481, King John II of Portugal commissioned Diogo d'Azambuja to build Elmina Castle, which was completed in 3 years.
By 1598, the Dutch had joined them, building forts at Komeda and Kormantsi. In 1617, they captured the Olnini Castle from the Portuguese, and Axim in 1642 (Fort St Anthony). Other European traders had joined in by the mid-17th century, largely English, Danes and Swedes. English merchants, impressed with the gold resources in the area, named
