Why were the first great geographical discoveries made in Spain and Portugal?

The first geographical discoveries were made by people from the coastal states: Spain, Portugal, England, etc. The reason for the popularity of travel in these countries was the lack of territory. Another major factor in discoveries is a modernized fleet. It was possible to get to new continents and lands only using floating facilities. These states have a favorable geographic location. They began to invent early flotation devices that helped them cross the world’s oceans in the 14th and 17th centuries.
