One role that geography played in helping the Roman empire was by providing natural barriers to invasions.
<h3>How did geography help the Roman empire?</h3>
The Roman empire in its early stages, was able to take advantage of natural barriers to protect it from invasion by hostile tribes and kingdoms.
For instance, the Alps in Northern Italy made it difficult to invade Roman areas in Italy from the North. And the fact that Italy was a peninsular meant that to invade it, one would have to invade by sea where the Roman navy was stationed.

Ivan III "the great" is the Ruler of Russia that defeated the Mongols. He tripled the territory of Russia under his rule and laid the foundations for the Russian state.
The correct answers are map making, compasses, and square sails .
Map making made significant progress during the Age of Exploration (when Europeans were sailing to Asia). Thanks to maps that accurately included North and South America and their separation from Asia, sailors were better able to navigate their way around the globe.
Compasses also helped tremendously. These devices helped sailors to find their bearings and assess what direction they were heading.
Lastly, square sails helped in the process of traveling from Europe to Asia. During this period, caravels became ships developed by the Portuguese. These easily movable ships often used square sails as a means to direct their boat.
