The Treaty of Paris, also known as the Treaty of 1763, was signed on 10 February 1763 by the kingdoms of Great Britain, France and Spain with Portugal after Britain`s victory over France and Spain during the 7-year war. The signing of the treaty officially ended the Seven Years` War, known as the French and Indian war in North American theatre, and marked the beginning of an era of British domination outside Europe. The treaty did not include Prussia and Austria, since five days later they signed a separate agreement, the Treaty of Hubertusburg. During the first years of Spanish rule, economic growth slowed despite the easing of ethnic and national tensions and the spectacular population growth of the colony. Beginning in 1770, the Spanish crown encouraged the development of Louisiana tobacco cultivation by committing the royal monopoly of tobacco in Mexico to purchase the entire harvest of the natchitoches region. Soon, the Louisiana product was in high demand, its quality was judged as one of the best in North America. When the Spanish first acquired Louisiana, forty-nine natchitoch planters harvested 80,000 pounds of tobacco per year; until 1791, eighty-three plantations yielded more than seven hundred thousand pounds. In this region, too, the population of free people and slaves has grown dramatically; the number of slaves more than tripled between 1765 and 1803, from 269 to 948. Tobacco production flourished so rapidly that 1,789 warehouses in Mexico and Spain were largely in surplus. Mexico stopped importing tobacco completely from Louisiana and Spain reduced its quota to 40,000 pounds, so that Natchitoches plantation pots remained unsuitable for buyers. The animal fur market had also collapsed in the 1770s due to oversupply.

In the 1790s, plantation pots in Louisiana began to disappear not only from tobacco, but also from indigo, as this crop was also difficult to sell on the world market. Meanwhile, Louisianans, without whom we can speak, still had to import basic items such as clothing, shoes, soap, glass bottles and alcohol. However, Spain`s strict trade restrictions have slowed the growth of imports and exports. During the American Revolution, the colonies allied with France to defeat Britain. After the war, the new American nation conquered the country that the British held between the Appalachians and the Mississippi River. Spain was no longer the predominant colonial threat it had been in the 17th century, but the United States took a position of diplomatic weakness because it owed a huge debt to Britain and France and did not have a navy to protect their shores. Spain was still a great threat and shared a long border with the United States. It was not until 1795, in picnkney`s contract, that the United States obtained free shipping rights from Spain to the Mississippi River and free storage to store goods until they were shipped abroad or upstream. Previously, goods were taxed and tolls were imposed for the use of the river. Louisiana was an anomaly in the Spanish Atlantic Empire. The Spanish central colonies – the viceroys of New Spain and Peru – were mainly structured to promote the mineral wealth of the slave aborigines.
