The Dutch built Fort Crèvecœur (later called Ussher Fort) to secure a trading foothold at Accra on the Gold Coast. The fort supported coastal commerce by protecting warehouses, negotiating space with local authorities, and giving Dutch traders leverage against rivals. It also became part of a wider fort network tied to Atlantic trade, including trade in enslaved people.
A timber fort at Cabo Corso (Cape Coast) was built for the Swedes in 1653 and became known as Carolusborg. Its location made it valuable for coastal trade, because it sat near important local markets and shipping routes. Control of this site would soon become a major prize in European competition on the Gold Coast.
The Dutch founded Fort Batenstein in 1656 as a fortified trading post on the western part of the Gold Coast. Forts like this supported the gold trade and other exports by creating defended points where ships could load goods and traders could store supplies. They also helped European companies bargain with, and sometimes pressure, nearby African states and towns.
In 1664 the British captured Cape Coast Castle, and over time turned it into a larger, heavily armed complex. From this stronghold, British traders could manage shipping, store goods, and coordinate inland buying networks for gold and other commodities, including enslaved people. Cape Coast became a central point of British influence along the Gold Coast shoreline.
At Kormantin (Abandze), an English fort site that later became known as Fort Amsterdam was captured by Dutch Admiral Michiel de Ruyter in 1665. The takeover showed how quickly military power could reshape commerce along the coast, because forts anchored trade contracts, shipping access, and local alliances. Control of Kormantin also mattered because it had been a major English base for Gold Coast operations.
In 1667 the Dutch West India Company built Fort Goede Hoop (Good Hope) at Senya Beraku. Like other forts, it served as a defended warehouse and negotiation point for coastal commerce. The fort later became part of the UNESCO-listed group of Ghana’s coastal forts because of its role in European trade systems tied to gold and the Atlantic slave trade.
The Treaty of Breda ended the Second Anglo-Dutch War in 1667 and included transfers of overseas possessions, including some African outposts. Even when a specific fort did not change hands, the treaty mattered on the Gold Coast because it influenced which powers could defend and supply their forts and ships. Diplomatic settlements like this shaped trade competition as much as local battles did.
In 1672 the Royal African Company (RAC) received a royal charter that supported an English monopoly over much of West Africa’s trade. On the Gold Coast, the RAC relied on forts and castles to collect goods, enforce contracts, and protect shipping. The company’s growth helped tie coastal commerce more tightly to the Atlantic economy, including the trade in enslaved Africans.
In 1673 the Royal African Company built Fort James at Accra as a fortified trading post for gold and enslaved people. Its construction placed the British next to Dutch and Danish forts in the same area, turning Accra into a multi-power commercial zone. This close proximity increased competition but also created a dense marketplace linking coastal brokers, inland suppliers, and Atlantic shippers.
Parliament’s African Company Act of 1750 (implemented through the early 1750s) dissolved the Royal African Company and transferred its forts and trading assets to a new regulated body, the Company of Merchants Trading to Africa (often called the African Company of Merchants). The change reflected debates in Britain about monopoly versus open trade and the high cost of maintaining forts. On the Gold Coast, forts such as Cape Coast Castle remained key administrative and commercial centers under the new arrangement.
The UK Slave Trade Act received royal assent on 25 March 1807 and took effect on 1 May 1807, making the British Atlantic slave trade illegal. This did not end slavery or all slave trading immediately, but it pushed British policy toward suppression and changed how coastal forts were used. Over time, British forts on the Gold Coast increasingly supported “legitimate commerce” (such as palm oil) and anti-slave-trade patrol and enforcement efforts, alongside older trading functions.
In 1821 Britain abolished the Company of Merchants Trading to Africa and vested its Gold Coast properties in the Crown. This shifted the coastal forts from being mainly company-run trade infrastructure to being tools of colonial administration and security. The change set the stage for deeper British involvement in coastal politics and conflicts with powerful inland states such as Asante.
On 21 January 1824, an Asante force defeated a British-led column under Governor Sir Charles MacCarthy at the Battle of Nsamankow. The battle showed the limits of coastal fort power when faced with large inland armies, even when the British had strong positions on the shore. It also influenced how Britain and coastal allies approached defense of trade routes and coastal towns.
On 7 August 1826, a combined force including British, local allies, and European partners defeated an Asante army near Dodowa (also called the Katamanso War). The outcome helped prevent Asante from dominating key coastal trading zones. This mattered for commerce because control of the coast affected customs collection, port access, and the safety of routes linking inland markets to the forts.
On 6 March 1844, several Fante leaders and British officials signed the Bond of 1844, an agreement that expanded British claims to exercise judicial authority in areas near the forts. The bond mattered for coastal commerce because courts and policing affected debt disputes, contract enforcement, and security for merchants and travelers. It became a major step toward more formal British colonial rule along the Gold Coast coastlands.
On 30 March 1850 Denmark sold its Gold Coast forts, including the key base at Christiansborg in the Accra area, to Britain. The transfer reduced the number of European competitors on the coast and helped Britain consolidate customs collection and security around major trading towns. It also marked a transition from a patchwork of rival trading enclaves toward a more unified British-controlled coastal zone.
