Lenin clashed with his Commissar for Nationalities over Stalin’s push for the integration of non-Russian republics into the Russian Soviet Federative Socialist Republic as autonomous republics. The leaders of these republics feared too much Russian power, and they were concerned that they could lose their right to secede from this union. They were right to be worried, as in theory this was protected but in practice there was no right to secession. Lenin sided with them against Stalin, and he agreed with their concern about Russian domination. However, real power continued to remain in Moscow, despite the supposedly devolved nature of Soviet power. Some areas, such as language, culture, and schooling, did prosper, but they did so only until the following decade when Stalin centralized power even further.
