Degania Alef
Ruppin was among the founders of the Brit Shalom peace movement, which supported a binational state, but he left Brit Shalom after the 1929 Hebron massacre. Thereafter he was convinced that only an independent Jewish state would be possible, and he believed that the way to bring about that state was through continued settlement. He headed the Jewish Agency between 1933 and 1935, and helped to settle the large numbers of Jewish immigrants from Germany who came in that period. Ruppin died in 1943. He was buried in Degania Alef.
