Today, for Meso- and Andean South America, the later periods are more often classified using the "Horizon" terminology, with "Early Horizon" typically broadly equating to the Late Formative stage. "Horizons" are periods of cultural stability and political unity, with "Intermediate periods" covering the politically fragmented transition between them. In the Andes, there are three Horizon periods, with two Intermediate periods between them. The Horizons, and their dominant cultures are: Early Horizon, Chavin; Middle Horizon, Tiwanaku and Wari culture; Late Horizon, Inca.
