Basilius is the Latinized form of Greek Basileios (Βασίλειος), derived from basileus, “king.” The name therefore carries the sense of royal, kingly, or regal. It gained prominence from early Christian saints, most notably Basil the Great (4th century), a Cappadocian theologian and bishop. Through ecclesiastical Latin, Basilius appears in medieval charters, university rolls, and monastic records, especially in German-speaking regions and the Low Countries where Latin given names were common in learned and clerical contexts.

Usage spread across the Christian world, flourishing in Orthodox lands and persisting in liturgical calendars. Related and regional variants include Basil (English), Basile (French), Basilio (Italian and Spanish), Basílio/Basílio (Portuguese), Vasile (Romanian), Vasil (Bulgarian and Macedonian), Vasyl (Ukrainian), Bazyli (Polish), and Vasily/Vasilii (Russian), as well as Vasilios or Vasileios (modern Greek). While Basilius itself is rare today outside church or academic circles, its shorter forms remain familiar and accessible.
