A native of Ikenne in Ogun State of south-western Nigeria, he started his career, like some of his well-known contemporaries, as a nationalist in the Nigerian Youth Movement in which he rose to become Western Provincial Secretary. Awolowo was responsible for much of the progressive social legislation that has made Nigeria a modern nation. Awolowo was the first Leader of Government Business and Minister of Local Government and Finance, and first Premier of the Western Region under Nigeria's parliamentary system, from 1952 to 1959. He was the official Leader of the Opposition in the federal parliament to the Balewa government from 1959 to 1963. In 1963 he was imprisoned under the accusations of sedition and was not pardoned by the government until 1966, after which he assumed the role as Minister of Finance. In recognition of all of this, Awolowo was the first individual in the modern era to be named as the leader of the Yorubas (Yoruba: Asiwaju Awon Yoruba or Asiwaju Omo Oodua).
