Spain benefited from the 1494 Treaty of Tordesillas as it kept Portugal out of most of the Americas.

Explanation:

The Treaty of Tordesillas was an agreement concluded in 1494 between Spain and Portugal where the border between the countries' overseas possessions was determined.

The Treaty involved the division of newly discovered areas outside Europe between Portugal and Spain. The border between the countries' overseas possessions was set to a line 370 leagues (2193 km) west of Cape Verde where what lay east of that line would belong to Portugal and that which was to the west would belong to Spain. The idea was to prevent an armed conflict between the most important Catholic countries of the time. In this way, Portugal could only access the eastern part of South America, leaving the rest of the continent under Spanish sovereignty.
