The evolution of the separation of church and state in American politics developed through historical precedents, particularly the First Amendment. Initially, this principle aimed to prevent government endorsement of a specific religion, reflecting the founders' experiences with religious persecution. Key court cases, such as Engel v. Vitale, have reinforced this separation by prohibiting school-sponsored prayers. Over time, a more stringent interpretation emerged, leading to broader implications for various public sectors. This ongoing evolution reflects the balance between religious freedom and the need for a neutral public sphere in the face of diverse beliefs.
