In the months leading up to the convocation of the congress, Stalin had wanted Ukraine, Belarus, and Transcaucasia—the federation of Armenia, Azerbaijan, and Georgia—to join the Russian Federation as autonomous republics like Bashkiria and the Crimea, which had already been incorporated with that status. They were to be subordinate to the Russian government in Moscow. Stalin had had to abandon his plan because of protests from the prospective republics and pressure from Lenin, who insisted on the creation of a federal union of equal republics, including Russia.
