Why were many European forts built along the coast of Ghana?

European forts were constructed along the coast of Ghana primarily to facilitate and control the lucrative trade that developed following the arrival of Portuguese mariners in 1471.123

The primary motivations for these structures included:

• Securing Trade Monopolies: The Portuguese, and later other European powers, built these stone fortresses on land leased from local states to ensure that local populations sold valuable commodities—initially gold—exclusively to their agents.12
• Commercial Infrastructure: These forts served as essential entrepôts for the storage of goods and the management of trade. As the focus of commerce shifted from gold to the slave trade to supply American plantations, the forts became central hubs for these operations.245
• Defensive and Administrative Presence: The forts provided a permanent base for European garrisons and administrators to protect their commercial interests against rival European nations and to exert influence over coastal trade routes.124

By the mid-18th century, approximately 40 such forts existed along the coast, reflecting the intense competition between European powers like the Dutch, British, and Danes to dominate the region's trade.24
