Požega County (; ) was a historic administrative subdivision (županija) of the Kingdom of Croatia-Slavonia. Croatia-Slavonia was an autonomous kingdom within the Lands of the Crown of Saint Stephen (Transleithania), the Hungarian part of the dual Austro-Hungarian Empire. Its territory is now in eastern Croatia. The capital of the county was Požega (Croatian, in Hungarian: Pozsega). Geography Požega county shared borders with the Austrian land Bosnia-Herzegovina and the counties of Zagreb, Bjelovar-Križevci, Virovitica and Srijem (all in Croatia-Slavonia). The county stretched along the left (northern) bank of the river Sava. Its area was 4933 km2 around 1910. History The territory of Požega County was part of the Kingdom of Croatia, a realm in personal union with the Kingdom of Hungary since 1102. Požega County was likely formed in the 12th century through partition of the Baranya County. The earliest historical record of Požega County as the comitatus de Posega survives from the a deed issued by king Andrew II of Hungary in 1210, confirming ownership of land left to the Knights Templar by the Palatine of Hungary Csépán Győr. The earliest surviving dated mention of the city of Požega (as castrum de Posega) dates to 11 January 1227 in a document issued by Pope Honorius III. The pope confirmed the decision of Andrew II granting the Archbishop of Kalocsa Ugrin Csák authority over Požega. In 1232, Ugrin established a Cistercian abbey in Gotó (also referred to as the Honesta Vallis) in present-day Kutjevo where monks first arrived from Zirc Abbey. In the 12th century, Benedictine Rudina Abbey was established in the west of the valley containing the county seat by Ban Borić or one of his sons. According to historian Nada Klaić, Borić owned estates in the area, including the Orljava Fortress, at the time and was likely the first comes (appointed head) of Požega County. The Franciscans established an abbey in Požega itself in the second half of the 13th century. Since at least 1217, the Požega Capitulum of St. Peter (Požeški kaptol sv. Petra) was established as the place of authentication in present-day Kaptol likely by Ban of Croatia and Bishop of Pécs Kalán. Ugrin died in the Battle of Mohi in 1241. Then, the title of county comes was awarded to Klet Kórógyi. He was killed the same year in battle with Mongols at the Orljava Fortress (near present-day Orljavac). The city of Požega was nonetheless held,
