The main settlement of the treaty was the setting of the border between the Spanish and Portuguese regions of 270 leagues further west from that set by the Inter caetera Bull of 1493. The Western shift of the demarcation line allowed the Spaniards to exert their dominance over more of what they thought was Asia. For the Portuguese, the location of the 370 league line west of the Cape Verde Islands allowed them to control the route to India that revolved around the Cape of Good Hope. Although there is no formal evidence, there is some evidence that the Portuguese were aware of the existence of land in the South Atlantic as early as 1493. The new agreement allowed them to guarantee sovereignty over what Brazil would become, officially discovered in 1500.
