The Friendship Agreement was the contract between George Washington and King Louis XVI of France following the former's exile from the United States about a year earlier. Louis XVI and France had been very supportive of Washington and the American colonists during the American Revolutionary War against the British only years earlier, which was the greatest factor which contributed to the King giving the Colony of Beauchemin to Washington. The terms of the contract was the the French who were then-currently living in the Colony be allowed to remain there unhindered (and be allowed to leave if they so wish) and that a quarter of certain resources gathered from the islands be shipped to France on an annual basis. In return, Washington gained full sovereignty over the islands, and within one month (at which time he considered himself President of Beauchemin) declared himself King. Beauchemin was within days after the declaration renamed to "Washingtonia".
The agreement was never officially given a name. When Washington and the colonial governor signed the agreement, the Governor is alleged to have said "And hereby on behalf of His Most Christian Majesty The King Louis Sixteen of the French, I sign this agreement of friendship between the honorable George Washington and the French." Although "Friendship Agreement" is the most widely used, even by the King of Washingtonia and the French government, many have called it the Beauchemin Agreement and the Washington Arrangement among others.
