The Treaty on the Creation of the USSR officially created the Union of Soviet Socialist Republics (USSR), commonly known as the Soviet Union. It de jure legalized a union of several Soviet republics and created a new centralized federal government (Congress of Soviets of the Soviet Union and Central Executive Committee of the Soviet Union (TsIK) were the legislative while Council of People's Commissars was the executive) where key functions were centralized in Moscow.

The Treaty along with the Declaration of the Creation of the USSR was approved on December 29, 1922 by a conference of delegations from the Russian SFSR, the Transcaucasian SFSR, the Ukrainian SSR and the Byelorussian SSR. The Treaty and the Declaration were confirmed by the 1st Congress of Soviets of the USSR and signed by heads of delegations  – Mikhail Kalinin, Mikhail Tskhakaya, Mikhail Frunze and Grigory Petrovsky, Aleksandr Chervyakov respectively on December 30, 1922. The treaty provided flexibility to admit new members. Therefore, by 1940 the Soviet Union grew from the founding four republics to 15 republics.
