The Luwians were an ancient people in Anatolia who spoke the Luwian language. During the Bronze Age, Luwians formed part of the population of the Hittite Empire and adjoining states such as Kizzuwatna. During the Hittite New Kingdom, Luwian replaced Hittite as the empire's dominant language. In the early Iron Age, a number of Luwian-speaking Neo-Hittite states arose in northern Syria. The Luwians are known largely from their language, and it is unclear to what extent they formed a unified cultural or political group.
