colonies) in 1834, and an apprenticeship period followed which ended in 1838. After its end, labour shortages on the plantations resulted, and were initially addressed by the immigration of indentured servants; in the late 1840s, many Portuguese immigrants arrived from Madeira, and between 1861 and 1888 shiploads of Indian labourers arrived. 20th century In 1902, the La Soufrière volcano erupted again, killing 1,500–2,000 people; much farmland was damaged, and the economy deteriorated. 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 the other Windward Islands as a single entity, to simplify 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 the British government. However, the attempt collapsed in 1962. Saint Vincent was granted "associate statehood" status by Britain on 27 October 1969. This gave Saint Vincent complete control over its internal affairs but fell short of full independence in law. In April 1979, La Soufrière erupted once more. Although no one was killed, thousands were evacuated and extensive agricultural damage occurred. On 27 October 1979, Saint Vincent and the Grenadines gained full independence; the date is now the country's Independence Day, a public holiday. The country opted to remain within the Commonwealth of Nations, retaining the then-Queen Elizabeth II as Monarch, represented locally by a Governor-General. Post-independence era Milton Cato of the centre-left Saint Vincent Labour Party (SVLP) was the country's first Prime Minister (he had been Premier since 1974), ruling until his defeat in the 1984 Vincentian general election by James Fitz-Allen Mitchell of the centre-right New Democratic Party (NDP). During Cato's time in office, there was a brief rebellion on Union Island in December 1979 led by Lennox 'Bumba' Charles. Inspired by the recent revolution on Grenada, Charles alleged neglect of the Union by the central government. However, the revolt was
