Constitutions of Clarendon
The clause was based on a number of precedents, including the Constitutions of Clarendon, the Bill of Rights 1689, and the Pennsylvania and New Jersey colonial constitutions. An initial draft by John Dickinson was prepared in conjunction with his drafting the Articles of Confederation. In 1789, then-congressman James Madison prepared another draft which, following discussion and debate in the First Congress, would become part of the text of the First Amendment of the Bill of Rights. The Establishment Clause is complemented by the Free Exercise Clause, which allows individual citizens freedom from governmental interference in both private and public religious affairs.
