A treaty between Spain and Portugal to divide up all the land of the earth outside of Europe (nonChristian land)
Treaty led by Pope Alexander VI
Preceded by Inter Caetera Papal Bull, issued on May 4, 1493. He drew imaginary line and gave Spain the land to the west Cape Verde Islands and Portugal the land to the east of it.
– all lands discovered west of a meridian 100 leagues (one league is 3 miles or 4.8 km) west of the Cape Verde Islands should belong to Spain while new lands discovered east of that line would belong to Portugal
– Entire New World was given to Spain; Africa and India to Portugal.
– The margin of the maneuver given to Portugal by the papal bull was small.
This papal bull also specified that all lands already under the control of a "Christian prince" would remain under that same control. King John II (the nephew of Prince Henry the Navigator) negotiated with King Ferdinand and Queen Isabella of Spain to move the line to the west. King John's rationale to Ferdinand and Isabella was that the Pope's line extends all around the globe, thus limiting Spanish influence in Asia.
Treaty
concluded in June 7, 1494.
– Spain and Portugal met at Tordesillas, Spain and signed a treaty moved the line 270 leagues west, to 370 leagues west of Cape Verde – This new line (located at approximately 46° 37') gave Portugal more claim to South America yet also provided Portugal with automatic control over most of the Indian Ocean.
Portugal
ended up colonizing places like Brazil in South America and India and Macau in Asia.
Portuguese-speaking population is a result of the Treaty of Tordesillas.
