Menachem Begin, 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.
[2] 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.
