and included most of the present-day states of Alabama and Mississippi (between 31° N and 35° N). The southern portion of this region was also claimed by Spain as part of Spanish Florida. One of Georgia's efforts to accomplish its goals for the region was a 1794 plan developed by governor George Mathews and the Georgia General Assembly. It soon became a major political scandal, known as the Yazoo land scandal. Spain had, since 1763, controlled the lands west of the Mississippi River. Those lands consisted of Spanish Louisiana and New Orleans. Great Britain, from 1763 to 1783, controlled the lands east of the Mississippi, British Florida, north from the Gulf of Mexico. Spain gained possession of British Florida south of 31° N and claimed the rest of itnorth to 32° 22′ (the junction of the Mississippi and Yazoo Rivers). Thereafter, Spain attempted to slow the migration of American settlers into the region, and to lure those already there to secede from the United States. Toward this end, in 1784 the Spanish closed New Orleans to American goods coming down the Mississippi, which was the only viable outlet for the goods produced by many American settlers, and began selling weapons to the Native tribes in the Yazoo. After Washington issued his 1793 Proclamation of Neutrality he became concerned that Spain, which later that year joined Britain in war against France, might work in concert with Britain to incite insurrection in the Yazoo against the U.S., using the opening of trade on the Mississippi as an enticement. At that same time though, mid-1794, Spain was attempting to extract itself from its alliance with the British, and to restore peace with France. As Spain's prime minister, Manuel de Godoy, was attempting to do so, he learned of John Jay's mission to London and became concerned that those negotiations would result in an Anglo-American alliance and an invasion of Spanish possessions in North America. Sensing the need for rapprochement, Godoy sent a request to the U.S. government for a representative empowered to negotiate a new treaty; Washington sent Thomas Pinckney to Spain in June 1795. Eleven months after the signing of the Jay Treaty, the United States and Spain agreed to the Treaty of San Lorenzo, also known as Pinckney's Treaty. Signed on October 27, 1795, the treaty established intentions of peace and friendship between the U.S. and Spain; established the southern boundary
