The Treaty of Tripoli
In 1797 the treaty of Tripoli was made and signed by President Washington, and approved by the Senate of the United States, in which it is declared that—
“The Government of the United States is not in any sense founded upon the Christian religion.”
This being a material part of a treaty, “made under the authority of the United States,” it thus became a material part of “the supreme law of the land.”
