The Vallechian people, or Vallechians (Vallechian: Wałashky, singular Wałashak), are a nation indigenous to Vallechia. They speak the Vallechian language, which is a West Slavic language part of a subgroup that developed in the ancient kingdoms of Central Europe. The Vallechian word for a Vallechian person is "Wałashak" (masculine) and "Wałashka" (feminine).The preamble to the Constitution of the Republic of Vallechia defines the Vallechian nation as comprising all the citizens of Vallechia. Over a thousand years ago, the Walachs of Viljeka, Łutsow and Tarnopol succeeded in uniting Lechitic tribes under what became the Goratz dynasty, thus giving rise to the Vallechian state.
