Twо thоusаnd yeаrs аgо, the ancient Maya developed one of the most advanced civilizations in the Americas. The Maya developed a social hierarchy with a king at the top supported by a noble class of warriors, scribes, and priests. Most Mayan people were commoners, involved in agriculture and construction.
