to lay down a special condition within the framework of an agreement. The King of Portugal, John II, who was not satisfied with this agreement, negotiated with the Spanish monarchs. At that time, Portugal had more ships and military power, so Spain was a bit at a disadvantage if negotiations failed and led to a struggle. The result of these negotiations was a revised north-south virtual line, 270 leagues west of the original line or 46°30? W of Greenwich. The new line effectively gave Portugal control of what Brazil is now. You will also notice that Brazil is located east of the line and was discovered on April 22, 1500 by the Portuguese explorer Pedro Alvares Cabral.

The bull did not mention Portugal or its lands, so Portugal could not claim newly discovered lands, even if they were located east of the line. . . .
