The Mayans were very civilized people that flourished between A.D. 300 and 900. They were one of the most sophisticated civilizations in the Americas. The Mayans built many wonderful things including pyramids, temples, and of course the Mayan calendar, which was the most accurate tool to keep track of the time back then. They were also farming people and they cleared the dense rain forests for there crops. There culture was centered in city-states and there civilizations included a lot of Central America and southern Mexico. Things were going great for the Mayans until sometime around 800 when the Mayan civilization began to decline. People today still don't know what happened during this time but they do have some theories. The most recent theory is the overuse of the land led to reduced crop yields. Whatever happened, though, cities like Tikal and Palenque were abandoned and covered with dense jungle growth like the ones they destroyed when they were first developing . These cities were not rediscovered until the 19th and 20th centuries.
One of the Mayan city-states named Tikal means "at the waterhole" and the city spread over 50 square miles and the population was about 100,000 people. The Mayans ate mostly fruits and vegetables including avocados, sweet potatoes, guavas, and tomatoes. The Mayans got most of their food by farming and some people would trade food.
The Mayan workers look like this above. The Mayans worshiped pyramids and believed in many gods such as Xibalba. They kept track of their time using the Mayan calendar (shown below).
