The separation of church and state emerged as a key principle in modern democracies, shaping the relationship between religious institutions and government. This concept evolved over centuries, influenced by philosophical, political, and social developments that challenged traditional power structures.

In the United States, the First Amendment established the framework for church-state separation, aiming to protect religious freedom while preventing government endorsement. This principle has been shaped by Supreme Court decisions, reflecting changing attitudes towards religion's role in public life throughout the modern era.
