As the government of the United States is not in any sense founded on the Christian Religion,—as it has in itself no character of enmity against the laws, religion or tranquility of Musselmen,—and as the said States never have entered into any war or act of hostility against any Mehomitan nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries.

Treaty of Tripoli, Article 11, signed at Tripoli on November 4, 1796, and at Algiers on January 3, 1797 and received ratification unanimously from the U.S. Senate on June 7, 1797; it was signed into law by John Adams (the original language is by Joel Barlow, U.S. Consul). This is a declaration of the secular character of the government of the United States, sometimes misattributed to John Adams, who signed the treaty into law. A portion is also sometimes misattributed to George Washington, and also misquoted as "This nation of ours was not founded on Christian principles."
