"Cursed is he who moves his neighbour’s boundary mark." (Deuteronomy 27)
After Columbus discovered America in 1492, tensions arose between Spain and Portugal over the possession of new territories. To avoid war, Pope Alexander VI mediated between the powers, leading to the 1494 Treaty of Tordesillas. The Treaty vaguely established a meridian off the coast of the Cape Verde Islands. Territories West of the meridian belonged to Spain, while lands east of the meridian were to be Portuguese.
