During World War II the majority of the tribe supported the Yugoslav Partisans. The Montenegrin committee of the Yugoslav Communist Party was dominated by Piperi clansmen prior to the war, and they were instigators of the July 1941 uprising. One of the most famous Piperi communists was Dr. Vukasin Markovic, a personal associate to Lenin, who came back after the October revolution from Russia to Montenegro, planning to stage a Soviet revolution. After its failure and his arrest, he fled to the USSR, where he assumed party duties.
