directly derive from a Germanic medieval term ban or bannum, the royal power of raising of armies and the exercise of justice later delegated to the counts, which was widely used in Francia. Archaeologist Vladimir Sokol (2007) independently came to a very similar conclusion relating it to the influence of Franks during their control of Istria and Liburnia. In 2013, historian Tomislav Bali noted the possible connection of the title with the military and territorial administrative unit bandon of the Byzantine Empire. The unit term derives, like the Greek bandon (from the 6th century) and Latin bandus and bandum (from the 9th century; banner), from the Gothic bandwō, a military term used by the troops who had Germanic or fought against Germanic peoples. Bali considered that the Croatian rulers possibly were influenced by the Byzantine model in the organization of the territory and borrowed the terminology and that such thesis can be related to Sokol's arguing of Western influence. Use of the title Sources from the earliest periods are scarce, but existing show that since Middle Ages "ban" was the title used for local land administrators in the areas of Balkans where South Slavic population migrated around the 7th century, namely in Duchy of Croatia (8th century–c. 925), Kingdom of Croatia, Hungarian kingdom and Croatia in union with Hungary (1102–1526), the Banate of Bosnia (1154–1377), and Banate of Macsó (1254–1496). According to Noel Malcolm, usage of the Croatian title "ban" in Bosnia indicates that political ties with the Croatian world was from the earliest times, while supreme leader of the Serbs has always been called the Grand Prince (Veliki Župan) and never the "ban". The meaning of the title changed with time: the position of a ban can be compared to that of a viceroy or a high vassal such as a hereditary duke, but neither is accurate for all historical bans. In Croatia a ban reigned in the name of the ruler, he is the first state dignitary after King, the King's legal representative, and had various powers and functions. In South Slavic languages, the territory ruled by a ban was called Banovina (or Banat), often transcribed in English as Banate or Bannate, and also as Banat or Bannat. Croatia Earliest mentioned Croatian ban was Pribina in the 10th century, followed by Godemir (969–995), Gvarda or Varda (c. 995–1000), Božeteh (c. 1000–1030), Stjepan Praska (c. 1035–1058), Gojčo (c. 1060–1069),
