Treaty on the Creation of the USSR
On the other hand, the region's strategic role decided its fate, as a full Union republic within the negotiations upon forming the future state. For one Leon Trotsky and his supporters within the Soviet leadership still supported its World Revolution concept, and as said above, viewed the Treaty of Riga as only a temporary setback to the process, and a future advance would require a prepared bridgehead. This justified giving the SSRB the status of a full union republic within the Treaty on the Creation of the USSR that was signed on 30 December 1922. SSR Byelorussia became a founding member of the Soviet Union in 1922 and became known as BSSR.
