Moisey Ostrogorsky

Moisey Yakovlevich Ostrogorski (also Ostrogorsky; Russian:Моисе́й Я́ковлевич Острого́рский; Belarusian:Майсе́й Я́каўлевiч Aстрaго́рскi; Grodno Governorate, Russian Empire, now in Belarus, 1854 – Petrograd, USSR, February 10, 1921) was a Russian political scientist, historian, jurist and sociologist. 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. As Ostrogorski noted, 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 Hrodna province in 1906-1907.
