Nykodym was an Eastern Orthodox bishop who served as the Archbishop of Kostroma and Galich. Born Nikolai Vasilyevich Krotkov in 1868 within the Kostroma Eparchy, he was the son of a priest. After completing his theological studies, he rose through the ecclesiastical ranks, serving as a monk, a rector, and eventually a bishop. During the turbulent revolutionary period, he held significant positions in Ukraine, including serving as a vicar to the Metropolitan of Kiev. He was ultimately martyred in 1938 after facing repeated periods of imprisonment.
