The history of Christianity in Hungary began in the Roman province of Pannonia where the presence of Christian communities is first attested in the 3rd century. Although the territory was under the successive control of the Huns, Germanic peoples, and Avars from the 5th century, Christian communities may have survived in the region of Lake Balaton up until the 9th century. Accordingly, Christianity had existed in the present-day territory of Hungary before the Hungarians settled there around 900 AD, but the question of continuity is unresolved.
