Pre-Columbian

Archaeological knowledge of Pre-Columbian civilisation in El Salvador is poor, due to its high population density limiting excavation, as well as volcanic eruptions blanketing potential archaeological sites. This lack of knowledge particularly effects the Preclassic Period and earlier.

A notable archaeological site in western El Salvador is Chalchuapa, which was first settled around 1200 BC, and became a major urban settlement on the periphery of the Maya civilization during the Preclassic Period and was heavily involved in the trading of valuable items like ceramics, obsidian, cacao and hematite. The settlement was heavily damaged around 430 AD by a volcanic eruption, after which it never regained its former prominence. Another major Pre-Columbian settlement is Cara Sucia in the far west of the country, which began as a small settlement around 800 BC at the beginning of the Middle Preclassic, during the Late Classic (600-900 AD), Cara Sucia emerged as a major urban settlement, before being abruptly destroyed during the 10th century.

The Pipil people, Nahua speaking groups migrated from Anahuac beginning around 800 AD and occupied the central and western regions of El Salvador. The Nahua Pipil were the last indigenous people to arrive in El Salvador. They called their territory Kuskatan, a Nawat word meaning "The Place of Precious Jewels," back-formed into Classical Nahuatl Cōzcatlān, and as Cuzcatlán. It was the largest domain in Salvadoran territory up until European contact. The term Cuzcatleco is commonly used to identify someone of Salvadoran heritage, although the majority of the eastern population has an indigenous heritage of Lenca origin, as do their place names such as Intipuca, Chirilagua, and Lolotique.

Most of the archaeological sites in western El Salvador such as Lago de Guija and Joya De Ceren indicate a pre-Columbian Mayan culture. Cihuatan shows signs of material trade with northern Nahua culture, eastern Mayan and Lenca culture, and southern Nicaraguan and Costa Rican indigenous culture. Tazumal 's smaller B1-2 structure shows a talud - tablero style of architecture that is associated with Nahua culture and corresponds with their migration history from Anahuac. In eastern El Salvador, the Lenca site of Quelepa is highlighted as a major pre-Columbian cultural center and demonstrates links to the Mayan site of Copan in western Honduras as well as the previously mentioned sites in Chalchuapa, and Cara Sucia in western El Salvador. An investigation of the site of La Laguna in Usulutan has also produced Copador items that link it to the Lenca-Maya trade route.
