The composition of the U.S. commission was unusual in that three of its members were senators, which meant, as many newspapers pointed out, that they would later vote on ratifying their own negotiations. [14] These were members of the U.S. delegation: the treaty was observed by both sides, although inaccurate maps of the treaty meant that the boundary between Texas and Oklahoma remained blurred for most of the 19th century. The U.S. border was extended with Mexico in 1848 by the Treaty of Guadalupe Hidalgo. The second type of violation occurred in 1802 when Spain, which controlled New Orleans, prevented American merchants from selling their goods in the city, a right earned for Americans by the Treaty of San Lorenzo, which traded along the Mississippi River. American merchants who clung to goods they could not sell demanded that Spain return them whole. East of the Divide, the Spanish Empire claimed all the lands south of the Arkansas River, which were west of the Medina River, and all the lands south of the Red River, which were west of the Calcasieu River. [Notes 9] The vast area disputed between the territorial claims of the United States and Spain was mainly occupied by Native Americans with very few traders from Spain or the United States. To the south, the disputed area between the Calcasieu River and the Sabine River included Los Adaes, the first capital of Spanish Texas. The area between the Calcasieu and Sabine rivers becomes a lawless no man`s land. The United States saw great potential in these Western countries and hoped to regulate their borders.
Spain, seeing the end of New Spain, hoped to assert its territorial claims before being forced to grant independence to Mexico (later in 1821). Spain hoped to reconquer much of its territory after regional demands for independence faded. When Cuba becomes part of the American Union and the Isthmian Canal is completed, which is now secured, Puerto Rico, Cuba, Hawaii and the Philippines will be outposts of the great republic, watching American interests on the trail of world trade in their triumphant march around the globe. Our people will soon see and feel that these island possessions belonging to the United States are natural and logical, and in the great role we will play in world affairs, we would not only abandon them, but we would wonder how we could realize how we could realize how our natural destiny would work without them. The magnificent chain of island estates that stretches across the world would not be complete without Cuba, the jewel of the West Indies. [36] Spanish subjects, the indigenous peoples of the peninsula, who reside in the territory in which Spain renounces or rests its sovereignty under this Treaty, may remain in or remove it from that territory, retaining all their property rights during the two years, including the right to sell or dispose of that property or its proceeds; and they also have the right to exercise their industry, trade and professions, subject to the laws applicable to other foreigners. .
