Herman of Kazan and Svyazhsk, born Grigory Fyodorovich Sadyrev-Polev, was a 16th-century Russian prelate who served as the archbishop of Kazan. After taking monastic vows at the Joseph-Volokolamsk Monastery, he became the leader of the Bogoroditsky Monastery in Sviyazhsk. He later held the position of Metropolitan of Moscow due to the insistence of Ivan the Terrible. Known for his principled stance, he opposed the Tsar's repressive policies, which resulted in his disgrace and eventual banishment from the capital.
