Who was the main target of Stalin's genocide?

Answer 1

He targeted basically anyone he thought who might ever be a threat to him, politically or otherwise. He didn't do the targeting himself, apart from people directly around him - which included practically everyone who had been in any way prominent at the start of the Communist revolution. Beria, chief of the Secret Police supplied him with long lists of 'unreliable' people on which Stalin simply wrote "Kill them all".

Local party leaders all over the USSR were also supposed to earmark 'enemies of the Revolution' in their provinces for liquidation. Any lack of zeal on their part would make them suspect themselves, so everyone came up with long lists of mostly innocent people, plus some personal enemies and competitors of the local Governors. In most cases it was enough to be formerly middle class or a 'kulak', a prosperous farmer to get on the lists.

Answer 2

Stalin persecuted Jews, kulaks (somewhat wealthy peasants), Ukrainians, and virtually everyone who disagree with or criticized him and his policies.
