First, Stalin was much better educated than Hitler
Revolution of 1905 and its aftermath: 19051912
In January 1905, government troops massacred protesters in Saint Petersburg. Unrest soon spread across the Russian Empire in what came to be known as the Revolution of 1905. Georgia was one of the regions particularly affected. Stalin was in Baku in February when ethnic violence broke out between Armenians and Azeris; at least 2,000 were killed. He publicly lambasted the "pogroms against Jews and Armenians" as being part of Tsar Nicholas II's attempts to "buttress his despicable throne"
Hitler's entry into politics
After World War I, Hitler returned to Munich. Without formal education or career prospects, he remained in the army.[84] In July 1919 he was appointed Verbindungsmann (intelligence agent) of an Aufklärungskommando (reconnaissance unit) of the Reichswehr, assigned to influence other soldiers and to infiltrate the German Workers' Party (DAP). At a DAP meeting on 12 September 1919, Party Chairman Anton Drexler was impressed with Hitler's oratorical skills. He gave him a copy of his pamphlet My Political Awakening, which contained anti-Semitic, nationalist, anti-capitalist, and anti-Marxist ideas.
