Saint Vincent and the Grenadines passed through various stages of colonial status under the British. A representative assembly was authorised in 1776, Crown Colony government was installed in 1877, a legislative council was created in 1925 with a limited franchise, and universal adult suffrage was granted in 1951. During the period of its control of Saint Vincent and the Grenadines, Britain made several attempts to unify the island with other Windward Islands as a single entity, with the aim of simplifying British control in the sub-region through a single unified administration. In the 1960s, the British again tried to unify all of its regional islands, including Saint Vincent, into a single politically unified entity under British control. The unification was to be called the West Indies Federation and was driven by a desire to gain independence from British government. However, the attempt collapsed in 1962.
