Ban of Slavonia

Ban of Slavonia sometimes also Ban of "Whole Slavonia", was the title of the governor of a territory part of the medieval Kingdom of Hungary and Kingdom of Croatia.
From 1102, the title 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 and Dalmatia, 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. From 1225, the title started being held by a separate dignitary from the title of the Ban of Croatia and Dalmatia, and existed until 1476, when it was joined with the latter title.
In the 13th and 14th centuries, the more extensive title of Duke of Slavonia was granted, mainly to relatives of Hungarian monarchs or other major noblemen.
According to the public law of the Kingdom of Hungary, bans were counted among the "Upper nobility (Kingdom of Hungary)#Dignitaries and office-holders (11-13th centuries)#The high-officers of [the realm and of the Royal Households|barons of the realm]" and thus they enjoyed several privileges connected to their office.
