At the Paris Peace Conference in 1919 President Wilson and British Prime Minister David Lloyd George, despite the objections of French President Georges Clemenceau and Italian Foreign Minister Sidney Sonnino, pushed forward an idea to convene a summit at Prinkipo between the Bolsheviks and the White movement to form a common Russian delegation to the Conference. The Soviet Commissariat of Foreign Affairs, under the leadership of Leon Trotsky and Georgy Chicherin, received British and American envoys respectfully but had no intentions of agreeing to the deal due to their belief that the Conference was composed of an old capitalist order that would be swept away in a world revolution. By 1921, after the Bolsheviks gained the upper hand in the Russian Civil War, executed the Romanov imperial family, repudiated the tsarist debt, and called for a world revolution by the working class, it was regarded as a pariah nation by most of the world. Beyond the Russian Civil War, relations were also dogged by claims of American companies for compensation for the nationalized industries they had invested in.
