Zompanco
Zompanco lay in the inland country of southern Mexico, where the Balsas River and its tributaries cut through valleys of maize land and mountain forest. Nahua-speaking communities farmed the valley floors and collected resin, copal and incense from the surrounding forest. Caravans carried these forest goods down to the river towns and onward to markets in the highland cities. Under the Mexica empire, the valleys around Tepecoacuilco paid tribute, and Zompanco's villages sent their share of forest products and cloth.
