Menachem Begin was an Israeli politician, founder of Likud and the sixth Prime Minister of Israel. Before the creation of the state of Israel, he was the leader of the Zionist militant group Irgun, the Revisionist breakaway from the larger Jewish paramilitary organization Haganah. He proclaimed a revolt, on 1 February 1944, against the British mandatory government, which was opposed by the Jewish Agency. As head of the Irgun, he targeted the British in Palestine. Later, the Irgun fought the Arabs during the 1947–48 Civil War in Mandatory Palestine and its chief Begin was also noted as "leader of the notorious terrorist organisation" by the British government and banned from entering the United Kingdom.
Begin was elected to the first Knesset, as head of Herut, the party he founded, and was at first on the political fringe, embodying the opposition to the Mapai-led government and Israeli establishment. He remained in opposition in the eight consecutive elections, but became more acceptable to the political center. His 1977 electoral victory and premiership ended three decades of Labor Party political dominance.
