Pinckney Treaty was an agreement ending disputes between the United States and Spain over possession of the Florida area and the mouth of the Mississippi River. The treaty, whose formal name was the Treaty of San Lorenzo, was signed on Oct. 27, 1795. Spain recognized the 31st parallel, the northern border of Florida, as the southern boundary of the United States. Spain agreed to let Americans land goods at New Orleans free of taxes for a period of three years. The two nations also agreed that this right could be renewed. Both nations gained free use of the Mississippi.
