Yitzak Rabin was the first native-born Israeli prime minister and served in this position from 1974 to 1977 and 1992 till his assassination in 1995. He was born in Jerusalem, in British-controlled Palestine. In 1941 during World War II, Rabin joined the Palmach, the secret commando unit of the major underground Jewish militia where he fought the influence of the Germans in the Middle East. After the war, the British restricted immigration of Jews into Palestine. Rabin participated in raids to free illegal immigrants in British detention centers. He retired from the army in 1968 and became Israel's ambassador to the United States. After improving relations with the U.S. he returned to Israel and became Prime Minister from 1974 to 1977. He lost the elections of 1977, even though having a very successful term. Rabin then returned as prime minister in 1992. In 1994, Rabin was awarded the Nobel Peace Prize for his work on peace settlements with the Palestine Liberation Organization. He also signed peace settlements with Jordan but was assassinated shortly after by an Israeli who disliked his views and actions. Rabin was a peacemaker and throughout his efforts had brought the Middle East closer and closer to a more stable region.
