ケルンテン公国
Pazin was first mentioned as "Castrum Pisinum" in a 983 deed regarding a donation by Emperor Otto II to the Diocese of Poreč. It then belonged to the Imperial March of Istria, which had originally been under the suzerainty of the newly established Duchy of Carinthia in 976, but separated together with the March of Carniola in 1040.
