Slavonia

Medieval Slavonia was a territory of the Hungarian and Croatian crowns governed by a ban. From 1225 its ban was a separate office from that of Croatia and Dalmatia, but the two offices were joined in 1476.

After the Treaty of Karlowitz transferred Ottoman lands to the Habsburgs in 1699, a Kingdom of Slavonia was formed from the recovered territory. Initially governed jointly by civil and military authorities, it received full civil administration in 1745 and was included administratively in Croatia and Hungary.
