The Masonic Founders also attempted to appease Muslims with passing the very first Treaty of Tripoli, where they explicitly stated that the US Government was not founded on Christian principles.

The Treaty of Tripoli Article 11 of the 1797 Treaty of Tripoli states that the U.S. government is "not in any sense founded on the Christian Religion" and that "no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries". This clause was intended to prevent religious conflict between the U.S. and the Muslim state of Tripoli and to reassure the Barbary state that America had no religious enmity. The article also asserted that the treaty was a peace agreement with no intention of hostility towards any "Mehomitan nation".
Purpose: The treaty aimed to end hostilities and ensure the safety of American ships from piracy in the Mediterranean. Article 11 was a key provision inserted to build trust between the two nations by emphasizing that U.S. foreign policy was not motivated by religious differences.
