On 13 January 1750, King John the V of Portugal and Ferdinand VI of Spain signed the Treaty of Madrid, in which the two sides attempted to establish the borders between Brazil and Spanish America, admitting that the Treaty of Tordesillas, as envisaged in 1494, had been annulled and considered inconclusive. Spain has recognized sovereignty over the Philippines, while Portugal would retain the territory of the Amazon basin. Portugal would abandon the colony of Sacramento on the north bank of the Plata River in present-day Uruguay, while receiving the territory of the Seven Missions.  The historic region of Mesoathst-America includes the present-day countries of North Costa Rica, Nicaragua, Honduras, El Salvador, Guatemala, Belize and Central Mexico. For thousands of years, this territory was colonized by groups such as the Olmec, Zapotec, Maya, Toltec and Aztec. The cultural characteristics that define the region are the domestication of maize, beans, avocado and vanilla and a common architectural style.

With the Treaty of Paris, it marked the end of the seven-year war. The treaty ended the continental conflict without major changes to the pre-war borders.
Above all, Silesia remained Prussian. The treaty, although it restored the pre-war status quo, marked the rise of Prussia as a leading European power. With the Treaty of Paris, Britain became the world`s largest colonial empire, which was its main objective in the war, and France lost most of its overseas assets. The term «Hubertsburg-Frieden» is sometimes used as a description of any treaty that restores the pre-conflict situation. The diplomats concluded their negotiations and signed the provisional treaty of Paris on November 3, 1762. Spanish and French negotiators also signed the Treaty of San Ildefonso, which confirmed the transfer of French Louisiana to Spain. The Anglo-French hostilities ended in 1763 with the Treaty of Paris, which included a complex series of land exchanges, the main one being the transfer of France to Spain from Louisiana and the United Kingdom to the rest of New France, with the exception of the islands of Saint-Pierre-et-Miquelon. Faced with the choice to reclaim New France or its Caribbean island colonies, Guadeloupe and Martinique, France opted for the latter to keep these lucrative sources of sugar and abolished New France as an unproductive and expensive territory.
On 7 June 1494, the Spanish and Portuguese governments approved the Treaty of Tordesillas, named after the spanish city where it was founded. The Treaty of Tordesillas included America`s «New World» between the two superpowers. Spain and Portugal divided the New World by controlling a north-south line of delimitation in the Atlantic Ocean, about 100 leagues (555 kilometers or 345 miles) west of the Cape Verde Islands, off Northwest Africa and then Portugal. All countries east of this line (about 46 degrees, 37 minutes to the west) have been claimed by Portugal. All the countries west of this line have been claimed by Spain. Spain and Portugal complied with the treaty without major conflict between the two, although the demarcation line was moved by an additional 270 leagues (about 1500 kilometers, or 932 miles) further west in 1506, allowing Portugal to claim the east coast of present-day Brazil.
