Along with Max Weber and Robert Michels, he is considered one of the founders of political sociology, especially in the field of theories about party systems and political parties.^[1] Ostrogorski noted that loyalty to parties is often comparable to loyalty to one's religion. He was a member of the First State Duma of the Russian Empire representing the Grodno province in 1906–1907.
