cultural extinction caused by Europeans intrusion into the Americas, bringing diseases and colonizing the Americas with warfare, terrorism, extremists radical Christianity and mass massacres. Only some Native American indigenous groups survived that catastrophe, most of them in Mexico, Central America and South America, with Salvadoran indigenous being one of many who have given rise to all modern Native Americans still alive today. Mesoamerican-Isthmus cultures Historically El Salvador has had diverse Native American cultures, coming from the north and south of the continent along with local populations mixed together. El Salvador belongs to both to the Mesoamerican region in the western part of the country, and to the Isthmo-Colombian Area in the eastern part of the country, where a myriad of indigenous societies have lived side by side for centuries with their unique cultures and speaking different indigenous languages of the Americas in the beginning of the Classic stage.

Guancasco is the annual ceremony by which Lenca communities, usually two, gather to establish reciprocal obligations in order to confirm peace and friendship.
