Menachem Begin (16 August 1913 – 9 March 1992) 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.

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 (except for a national unity government around the Six-Day War), but became more acceptable to the political center. His 1977 electoral victory and premiership ended three decades of Labor Party political dominance.

Begin’s most significant achievement as Prime Minister was the signing of a peace treaty with Egypt in 1979, for which he and Anwar Sadat shared the Nobel Prize for Peace. In the wake of the Camp David Accords, the Israel Defense Forces (IDF) withdrew from the Sinai Peninsula, which was captured from Egypt in the Six-Day War.
