I want to know the answer to the following question:
On what date was the office of President of the RSFSR created?
All the background I'm provided with is that "During an unsuccessful coup attempt on August 19–21, 1991 in Moscow, the capital of the Soviet Union and Russia, President of Russia Yeltsin strongly supported the President of the Soviet Union, Mikhail Gorbachev.". Is that enough to answer the question?
