The biggest conflict that the Portuguese faced was deciding who owned what land between them and Spain. It was settled by a treaty which basically drew an imaginary line from north to south that separated Spain’s land and Portugal’s land. Spain got the Eastern land and Portugal got the Western land. The Line of Demarcation was drawn about 100 leagues west of the Cape Verde Islands. The Portuguese ruler, King John II, was mad that Portugal had no representation in the New World and they didn’t have enough space in the East to continue with their African Expeditions, so he had a meeting with Spain at Tordesillas. The treaty that was created here will be known as the Treaty of Tordesillas. This treaty moved the Line of Demarcation 270 leagues
