After the first Zionist Congress, the renowned Marxist Ber Borochov developed the rigorous policies of the Zionist Project. He argued territorial concentration as a solution to, among other things, the Jewish question. He founded Poalei Zion, the Marxist Zionist Party which supported the Russian Revolution in 1917. David Ben Gurion, one of the Party members and Israel's founder, came to Palestine at the beginning of the twentieth century. He considered himself a Bolshevik and was in favour of the dictatorship of the proletariat in all countries, except Palestine where he favoured the dictatorship of Zionism. Ben Gurion considered Jewish national interests superior to class interests in Palestine: a clear case of unmitigated National Socialist leanings.
