The Establishment Clause is a provision in the First Amendment of the United States Constitution that prohibits the government from establishing a religion. This means that the government cannot favor one religion over another, or religion over non-religion, and cannot make any law "respecting an establishment of religion"
. The precise definition of "establishment" is unclear, but it is generally understood to mean that the government cannot sponsor or promote a particular religion or religious belief
. The Establishment Clause is one of two provisions in the First Amendment concerning religion, the other being the Free Exercise Clause, which protects citizens' right to practice their religion as they please, so long as it does not interfere with the rights of others
