Hermogenes of Moscow was a 17th-century Russian Orthodox patriarch who played a decisive role in ending the Time of Troubles. Born in Kazan around 1530, he served as the Metropolitan of Kazan before being elected to the primatial See in 1606. He is best known for his steadfast opposition to Polish rule and his efforts to inspire a popular uprising against foreign intervention. His refusal to compromise his religious convictions led to his arrest and eventual martyrdom in the Chudov Monastery.
