Betar (B'rith Trumpeldor)
BETAR (B'rith Trumpeldor)
Jewish extremist movement founded in 1923 by Vladimir Ze'ev Jabotinsky in Riga, Latvia, for the training of the future cadres of revisionist Zionism. Betar's program was built around an intense political and paramilitary education. Once transformed into a veritable militia, the movement was integrated into the Herut Party of Menachem Begin. Betar is likewise the name of the fortress from which Bar Kochba directed the revolt against the Roman legions in Palestine, in 135 c.e.
