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,[13] and universal adult suffrage was granted in 1951.[13] During the period of its control of Saint Vincent and the Grenadines, Britain made several attempts to unify the island with the other Windward Islands as a single entity, to simplify British control in the sub-region through a single unified administration.[13] 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 the British government. However, the attempt collapsed in 1962.[13]
