Incan Civilization

The Incan Empire was a strong and clever tribe which turned out to be an army. Even if the tribe turned out to be an army most of the Incas were farmers. The Incas were excellent farmers, builders and managers. They were originally living in the Andes mountains but they immigrated a lot. The Incas were well known because of their amazing inventions at the time. Here are some examples:
The Incas had a way to keep track by putting knots on pieces of string.
They were masters at building things in stones, like houses and other things were you could live in. They used a lot the rock because they lived close to the mountains and that material was the most available.
They also made buildings that were earthquake proof. They did this by carving the stones perfectly meaning that no cement (or paste between the stones) was needed. It fit together perfectly, and even now, you cannot slip a piece of paper through the walls. They were water proof too!
Another clever thing they discovered was making aqueducts. These dips in the ground transported water from long distances all the way back to their crops and irrigate the land.
The Incas were also known for their pottery work. They made the pots in a way similar to how we make nowadays, but the designs on the pottery were outstanding.

One of the most clever inventions the Incas had was to carve terraces into the side of mountains and hills, allowing them to grow crops in what would be inaccessible areas, and thrive there without trouble.
