Treaty of Madrid (1750)
The Treaty of Madrid of 1750 between Portugal and Spain replaced the line of the Treaty of Tordesillas with borders in South America based on actual occupation. Portugal secured most of the Amazon basin and the interior of Brazil, giving up Colonia do Sacramento in exchange for the Seven Missions east of the Uruguay River. Joint commissions were sent to map the frontiers, and the treaty was annulled in 1761.
