Treaty of Tordesillas

7 June 1494, Tordesillas, Spain

Signed in 1494, the treaty divided the New World between Spain and Portugal while ignoring the millions of indigenous people who lived there. The subsequent colonisation and conquest of these lands had a devastating impact, with civilizations such as the Inca and the Aztec being wiped out. Imagesource:wiki/bibliothèque Nationaledefrance
