I want to know the answer to the following question:
Which union did Russia belong to after 1922?
All the background I'm provided with is that "commonly referred to as Soviet Russia or simply as Russia, was a sovereign state in 1917–22, the largest, most populous, and most economically developed republic of the Soviet Union in 1922–91 and a sovereign part of the Soviet Union with its own legislation in 1990–91.". Is that enough to answer the question?
Answer: yes
