Commonwealth of Independent States
Background

The CIS as a shared Russophone social, cultural, and economic space has its origins in the Russian Empire, which was replaced in 1917 by the Russian Republic after the February Revolution earlier that year. Following the October Revolution, the Russian Soviet Federative Socialist Republic became the leading republic in the Soviet Union (USSR) upon its creation with the 1922 Treaty and Declaration of the Creation of the USSR along with Byelorussian SSR, Ukrainian SSR and Transcaucasian SFSR.

In March 1991, amidst Perestroika and a rising political crisis in the country, Mikhail Gorbachev, the president of the Soviet Union, proposed a federation by holding a referendum to preserve the Union as a union of sovereign republics. The new treaty signing never happened as the Communist Party hardliners staged an attempted coup in Moscow August that year.
