The Paris Peace Conference, which was convened to work out the conditions for post-war settlement after the end of the First World War and to sign peace treaties with the defeated powers of the Triple Alliance, was held in Paris from January 1919 to January 1921.
Russia was not invited for two reasons.
The first is that she signed a separate peace with Germany, thereby violating the agreements with the allies in the Entente.
And second, it was the international isolation of the Soviet state. At the time of the convening of the conference, more than one state had not recognized Soviet Russia, and in 1919 the countries of the West and Japan even attempted to intervene.
