The first five centuries of Christian pre-eminence in what is now modern Hungary present their own special questions. Among them, did the end of the 5th century mean a real break in the whole of the Christian world or only in Pannonia (modern Hungary), or should a chronological boundary be drawn at some other date? This survey divides the period into two, before and after Constantine (ancient and early Christianity), and, from the evidence of the finds, explores the important changes that occurred in the era. The results throw considerable light on the populations of the various faiths and the gradual acknowledgment of the Christian religion.
