Moshe Shamir (Hebrew: משה שמיר; 15 September 1921 – 20 August 2004) was an Israeli author, playwright, opinion writer, and public figure.He began his political career as a member of the movement Hashomer Hatzair, in which he filled a leadership role.The first opposition came from Meir Ya'ari, leader of the left-wing movement to which Shamir belonged, concerning what was perceived as "ideological aberration" in his stories.In his 1947 novel He Walked Through the Fields, which became the first play performed in the established State of Israel, the hero is a native-born Israeli, a "Sabra".Menachem Begin recalled Klausner's words in a later day when Moshe Shamir, as a member of the Knesset, crossed the political lines from left to right to oppose the Israel-Egypt Peace Treaty.He was among the founders of the "Bnai" faction (acronym for a phrase meaning "Union of Eretz Israel Faithful") that opposed the Camp David Accords (1978).In late 1979, after the Israel-Egypt peace treaty, he broke away from Likud, along with Knesset member Geula Cohen, and found the Tehiya Bnai party.
