Did Karl Marx predict russia to be first socialist nation?

No, Marx anticipated that Germany or England would become the first socialist countries because they were the most industrialized of the capitalist countries. Because of that they had the most developed proletariat. Marx believed the workers revolution required that intense capitalist phase in order to crystallize the differences between the bourgeoisie and the proletariat. In Russia, that hadn't happened yet, so Marx did not see communism taking root in Russia yet. In fact, he thought Russia was totally unsuitable at the time.
