Centuries ago, the Maya civilization inhabited large areas of Central America. They were incredibly sophisticated people who developed an advanced system of writing and mathematics. They built magnificent stone temples and pyramids without modern technology.

For many years, the Maya prospered in their territory. However, around the 9th century, something unusual happened. Suddenly, they abandoned their great cities. Modern archaeologists deciphered their hieroglyphics recently and discovered that war, drought, and overpopulation were possible reasons for their collapse.

Last year, an expedition found a deserted city deep in the jungle. They didn't see any gold, but they collected many artifacts like pottery and tools. These discoveries eventually helped us understand how they lived. Did the Maya disappear completely? No, their descendants stayed in the region and preserved their culture. It was a surprising conclusion to a long historical mystery.
