The history of the city of Fort-de-France is inextricably linked with the French colonization of Martinique. In 1637, French colonists turned their attention to a strategically important bay on the island's west coast. The first military fort, constructed from a palisade, appeared here around 1638–1640 to protect the settlers. The official founding date of the city, originally named Fort-Royal, is considered to be 1672, when the construction of a more substantial fortress began by order of Louis XIV. The city received its current name, Fort-de-France ("Fortress of France"), during the republican period, after 1793.
Several key factors contributed to the city's development. Firstly, its geographical location: the deep and well-protected bay was an ideal place for military and merchant ships to dock, unlike the open ports of other settlements. Secondly, the city quickly acquired the status of the island's main military and administrative centre, becoming a stronghold of French power in the Caribbean region. It was here that the political and military power of the colony was concentrated. After the devastating eruption of Mount Pelée in 1902, which destroyed the city of Saint-Pierre, Fort-de-France was definitively established as the economic and cultural capital of Martinique.
From the very beginning, the economy of Fort-Royal was based on trade. It became an important port for the export of colonial goods such as cane sugar, rum, coffee, and cotton, the production of which was supported by the labour of enslaved people. City life was centred around the port and the garrison. Despite frequent challenges, including epidemics due to the swampy terrain, natural disasters, and military conflicts, Fort-Royal gradually grew. Its culture represented a blend of French traditions brought by the colonists and Creole elements formed in the unique conditions of the West Indies.
