Banovina of Slavonia

Ban of Slavonia or the Ban of the Whole of Slavonia (Croatian: Slavonski ban, Ban cijele Slavonije, Hungarian: szlavón bán, Latin: regni Sclavoniæ banus) was the title of the governor - ban - of a territory part of the medieval Kingdom of Hungary and Kingdom of Croatia.

In the Kingdom of Croatia, Demetrius Zvonimir was the only notable ban, under king Peter Krešimir IV of Croatia. In the Kingdom of Hungary, the ban of Croatia was appointed by the kings of Hungary, and there was at first a single ban for all of the Kingdom of Croatia, but later the Slavonian domain got a separate ban. It included parts of present-day Central Croatia, western Slavonia and parts of northern Bosnia and Herzegovina. The title started being held by a separate dignitary from the title of the Ban of Dalmatia and Croatia in 1225, and existed until 1476, when it was joined with the latter title.

According to the public law of the Kingdom of Hungary, the Bans were counted among the "barons of the realm" and thus they enjoyed several privileges connected to their office.
