The Seychelles islands remained uninhabited for more than 150 years after they became known to Western explorers. The islands appeared on Portuguese charts as early as 1505, although Arabs may have visited them much earlier. In 1742, the French Governor of Mauritius, Mahe de Labourdonais, sent an expedition to the islands. A second expedition in 1756 reasserted formal possession by France and gave the islands their present name in honor of the French finance minister under King Louis XV. The new French colony barely survived its first decade and did not begin to flourish until 1794, when Queau de Quincy became commandant.

The Seychelles islands were captured and freed several times during the French Revolution and the Napoleonic wars, then passed officially to the British under the 1814 Treaty of Paris.

From the date of its founding by the French until 1903, the Seychelles colony was regarded as a dependency of Mauritius, which also passed from the French to British rule in 1814. In 1888, a separate administrator and executive and administrative councils were established for the Seychelles archipelago. Nine years later, the administrator acquired full powers of a British colonial governor, and on August 31, 1903, Seychelles became a separate British Crown Colony.

By 1963, political parties had developed in the Seychelles colony. Elections in 1963 were contested for the first time on party lines. In 1964 two new parties, the Seychelles Democratic Party (SDP) led by James Mancham, and the Seychelles People's Unity Party (SPUP) led by France Albert Rene, replaced existing parties.

In March 1970, colonial and political representatives of Seychelles met in London for a constitutional convention. Elections in November 1970 brought the resulting constitution into effect. In the November 1970 elections, the SDP won 10 seats, and the SPUP won 5 in the Legislative Assembly. Under the new constitution, Mancham became the Chief Minister of the colony.
