Królewiec Voivodeship

The Królewiec Voivodeship was a short-lived voivodeship of the Crown of the Kingdom of Poland, with capital in the city of Królewiec (now Kaliningrad, Russia), that existed during the Thirteen Years' War. It was established by king Casimir IV Jagiellon in April 1454, following the incorporation of the city and the surrounding area into Poland, from the territory of the State of the Teutonic Order. Following the capitulation of Polish forces in the battle of Kneiphof, on 14 February 1455, the voivodeship fall under the control of the Teutonic forces. The voivodeship formally ceased to exists following the signing of the Second Peace of Thorn, on 19 October 1466, which affirmed its area under the ownership of the State of the Teutonic Order, as a part and fief of Poland.

Government
The region was governed by the voivode. The only voivode of the voivodeship Ścibor Bażyński, who was in the office from April 1454 to 1455. The last mention of Ścibor, that refers to him as the voivode of Królewiec, comes from 12 April 1455. Due to the ongoing fighting in the region during the Thirteen Years' War, and later its occupation, the voivodeship did not have an organized administration, nor appointed the new voivode after 1455.
