The treaty ended the first era of U.S. expansion by providing for the surrender of Eastern floridas under Article 2; the abandonment of the Controversy over West Florida under Article 2 (part of which has been seized by the United States); and the definition of a border with the Spanish province of Mexico, which clearly made Spanish Texas part of Mexico under Article 3, thus ending much of the indeterminacy at the louisiana purchase border. Spain also transferred its rights to the Oregon Country under Article 3 to the United States. The two high-ranking contracting parties agree to cede and relinquish all their rights, rights and rights to the territories described in this line, i.e. the United States cede to Her Catholic Majesty and forever renounce all its rights, rights and rights over the territories west and south of the line described above; and in the same way, His Catholic Majesty ceded to the United States above all its rights, rights and claims to all the regions to the east and north of this line, and for himself, his heirs and successors, he renounced all pretensions on these territories forever. Eighty-eight years ago, on February 22, 1819, the United States and Spain signed the Adams Ons Treaty (also known as the Florida Purchase Treaty or Transcontinental Treaty of 1819), with which the United States acquired Florida from Spain and the two countries ended their border dispute over Western territories. Thanks to the treaty, we have become a nation from the sea to the luminous sea. Merchant vessels of one of the contracting parties that settle in a port of the enemy of the other party and of which they are only suspected of travel and type of goods on board are required to issue, on the high seas as in ports and ports, not only their passports, but also explicit statements that their goods are not among those who have been banned as contraband. To implement the previous article, a member of the Commission and a surveyor are appointed by each contracting party who meet in the Natchez, on the left of the Mississippi River, before the expiry of this convention, and they conduct and mark this limit in accordance with the provisions of this article. They hold platts and keep notebooks of their procedures, considered part of this Convention, and have the same strength as if they had been inserted into them. (1) If it is in any event deemed necessary for the aforementioned commissioners and surveyors to be accompanied by guards, they will be accompanied equally by the commander of Her Majesty`s troops in both Floridas and the commander of the United States forces on their southwestern territory, acting with consent and amicable. , as well as the provision of requests and instruments and any other provision that may be necessary or useful for the implementation of this article.
Prior to 1789, Spanish policy had focused on the minimal limitation of American trade and settlement in border areas, and therefore neither Spanish colonial officials nor Madrid politicians were interested in the concessions that the United States would obtain.
