Tunku Abdul Rahman resigned in 1970 and was replaced by Abdul Razak Hussein. Razak encouraged Mahathir back into the party and appointed him as a Senator in 1973. He rose quickly in the Razak government, returning to UMNO's Supreme Council in 1973, and being appointed to Cabinet in 1974 as the Minister for Education. He also returned to the House of Representatives, winning the Kedah-based seat of Kubang Pasu unopposed in the 1974 election. One of his first acts as Minister for Education was to introduce greater government control over Malaysia's universities, despite strong opposition from the academic community. He also moved to limit politics on university campuses, giving his ministry the power to discipline students and academics who were politically active and making scholarships for students conditional on the avoidance of politics.
