How did Stalin treat religious people?

Stalin's regime was marked by a strong anti-religious stance, viewing religion as a threat to the state's authority and ideology. Religious institutions, particularly the Russian Orthodox Church, faced severe repression, including the closure of churches, persecution of clergy, and promotion of Atheism through state Propaganda. Many religious leaders and practitioners were arrested, imprisoned, or executed during Stalin's purges. Overall, Stalin aimed to eradicate religious influence in society and replace it with state-sponsored ideology.
