Pre-Columbian

The first evidence of human settlers in Guatemala goes back to at least 10,000 BC. There is some evidence that may put this date 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. Archaic sites have been documented in Quiché in the Highlands and Sipacate, Escuintla on the central Pacific coast (6500 BC).

Archaeologists divide the pre-Columbian history of Mesoamerica into 3 periods: the Pre-Classic from 2000 BC to 250 AD, the Classic from 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, but 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, Tintal, Wakná and El Mirador.
