Ethnic minorities resented the government because of its "Russification", discrimination and repression, both social and formal, such as banning them from voting and serving in the Guard or Navy and limited attendance in schools . A nascent industrial working class resented the government for doing too little to protect them, banning strikes and labor unions . Finally, the educated class fomented and spread radical ideas after a relaxing of discipline in universities allowed a new consciousness to grow among students . </P> <P> Vladimir Lenin was a political theorist who also contributed his own ideology of how a revolution would be caused .
