Calypso drew upon African and French influences, and became the voice of the people. It allowed the masses to challenge the actions of the unelected Governor and Legislative Council, and the elected town councils of Port of Spain and San Fernando. As English replaced patois (French Creole) as the dominant language, calypso migrated into English, and in so doing it attracted more attention from the radio stations and government. Calypso continued to play an important role in political expression, and also served to document the history of Trinidad and Tobago.
