Note 256 — Chapter IX

Since the discovery of America the Spaniards and the Portuguese had been in constant rivalry throughout the south-eastern portion. Their frontier, between what are now Brazil and Argentina, had never been defined. In 1494 King John II. of Castile concluded a treaty signed at Tordesillas with the King of Portugal, placing the dividing-line between the countries two hundred leagues more to the westward than that of the famous Bull of Pope Alexander VI. (May 4, 1493), which placed it at one hundred leagues west of Cape Verd, cutting the world in two from the Arctic to the Antarctic Pole. From the signing of the treaty of Tordesillas trouble began in South America between the Powers, as by that treaty a portion of Brazil came into the power of Portugal.
