Many feats of Aztec engineering were made necessary by Tenochtitlan's location on a small island in a shallow lake.

Because they lived on an island, the Aztecs used their engineering skills to control the flow of water, to build artificial islands to create more farmland, and to build roads to connnect the city.

Another important ancient Greek concept that influenced the formation of the United States government was the written constitution. The original U.S. voting system had some similarities with that of Athens. In Athens, every citizen could speak his mind and vote at a large assembly that met to create laws.
