Famous Israeli People

[The Wizard]

Yep, Marx was a Jew. Just like quite a lot of the Bolshevik (and Menshevik) revolutionaries. Jews first, Georgians later, and Russians all the time...

Really? I'll keep that in mind. Strange that Wiki doesn't say that, they tend to mention jewish descent in their articles.

Yep, Trotsky (naturally), Kamenev (his mother wasn't Jewish, though), Zinoviev, Sverdlov (likely ordered Nicholas II's death), Uritsky (first head of the Cheka), Sokolnikov (created the U.S.S.R.'s first stable currency), Genrikh Yagoda (yet another Cheka peep), and later Kaganovich (a homie of Stalin's).

But, overall, the highest percentage they ever formed was around 6-10% in the Bolshevik Party (the so-called "Old Guard") and the Communist Party of the Soviet Union. Jewish communism, indeed...

Rosa Luxemburg, one of the leaders of the revolution in Germany was also a jew. And I seem to remember that there were a few more jews among the leadership back then.

There are some who believe that it was the communist revolution in Germany that led to Hitler's hatred for the jews, for as he saw it (through the eyes of a Freikorpsman) communist = jew.
I don't know if that was the case...

But there were a surprising number of jews in the most visible leadership. In total they might not have been too many.

As far as the Communist Party of the Soviet Union was concerned (as well as its predecessor, the Bolshevik Party), Jews were a minority.

They were well-represented in the higher echelons initially, true, and socialism and the way of the narodnik may have been an appealing alternative to Zionism for the average Jew in Russia, but they were quite the minority within Party ranks.

Russians formed the majority -- 60% in 1917, IIRC -- and that only increased as time passed.
