Contribution of the Party of Communists, USA (PCUSA) at the Scientific Conference in honor of the 100 years since the October Revolution.
Leningrad, August 10-13, 2017.
This year we celebrate the 100th anniversary of the socialist revolution in Russia. It was the first time that the working class anywhere in the world was able to seize and hold power. The revolution grew out of the conditions of imperialism and the First World War. Russia had been ruled by a tsar, or emperor, making it one of the most reactionary regimes in Europe.
