Pre-Columbian
The first evidence of human settlers in Guatemala demonstrates a presence at least as early as 12,000 BC. Some evidence suggests a presence as early as 18,000 BC, such as obsidian arrow heads found in various parts of the country. There is archaeological proof that early Guatemalan settlers were hunters and gatherers, but pollen samples from Petén and the Pacific coast indicate that maize cultivation was developed by 3500 BC. Sites dating back to 6500 BC have been found in Quiché in the Highlands and Sipacate, Escuintla on the central Pacific coast.
Archaeologists divide the pre-Columbian history of Mesoamerica into the pre-Classic period (2000 BC to 250 AD), the Classic period (250 to 900 AD), and the Calistic from 900 to 1500 AD. Until recently the Pre-Classic was regarded as a formative period, with small villages of farmers who lived in huts, and few permanent buildings. However, this notion has been challenged by recent discoveries of monumental architecture from that period, such as an altar in La Blanca, San Marcos, from 1000 BC; ceremonial sites at Miraflores and El Naranjo from 801 BC; the earliest monumental masks; and the Mirador Basin cities of Nakbé, Xulnal, El Tintal, Wakná and El Mirador.
El Mirador was by far the most populated city in pre-Columbian America. Both the El Tigre and Monos pyramids encompass a volume greater than 250,000 cubic meters. Mirador was the first politically organized state in America, named the Kan Kingdom in ancient texts. There were 26 cities, all connected by Sacbeob (highways), which were several kilometers long, up to 40 meters wide, and two to four meters above the ground, paved with stucco, that are clearly distinguishable from the air in the most extensive virgin tropical rain forest in Mesoamerica.
The Classic period of Mesoamerican civilization corresponds to the height of the Maya civilization, and is represented by countless sites throughout Guatemala, although
