{{Main|Treaty of Madrid (13 January 1750)}}

On January 13, 1750, [[King John V of Portugal]] and [[Ferdinand&nbsp;VI of Spain]] signed the Treaty of Madrid, in which both parties sought to establish the borders between Brazil and Spanish America, admitting that the Treaty of Tordesillas, as it had been envisioned in 1494, had been superseded, and was considered void. Spanish sovereignty was acknowledged over the Philippines, while Portugal would get the territory of the Amazon River basin. Portugal would relinquish the [[Colonia del Sacramento|colony of Sacramento]], on the [[Bank (geography)|left bank]] of the [[Río de la Plata|River Plata]] in modern-day Uruguay, while getting the territory of the [[Misiones Orientales|Seven Missions]].<ref>José Damião Rodrigues, Pedro Aires Oliveira (2014) [https://books.google.com/books?id=DwbhrQEACAAJ&q=hist%C3%B3ria+da+expans%C3%A3o+e+do+imp%C3%A9rio+portugu%C3%AAs ''História da Expansão e do Império Português''] ed.

Following the [[Guarani War]], the treaty was annulled by Spain and Portugal in the [[Treaty of El Pardo (1761)]]. The border was  eventually settled in the [[First Treaty of San Ildefonso]] in 1777, with Spain acquiring territories east of the [[Uruguay River]] and Portugal acquiring territories in the [[Amazon Basin]].
