Konrad IV the Older

Konrad IV the Older (Polish: Konrad IV Starszy) (ca. 1384 – 9 August 1447) was a Duke of Oels (Oleśnica), Koźle, half of Bytom and half of Ścinawa during 1412–1416 (with his brothers as co-rulers), since 1416 sole ruler over Kąty (Kanth), Bierutów, Prudnik and Syców and since 1417 Bishop of Wroclaw and Duke of Nysa.

He was the eldest son of Konrad III the Old, Duke of Oleśnica, by his wife Judith. The name of Konrad was also wore by his four younger brothers; they were identified by historians only through letters and regnal numbers.

Despite the fact that he was the oldest son and had a strong possibility of inherired all his father's duchy, Konrad IV chosen to follow a religious career. He grown rapidly in the Church hierarchy. By the end of 1399, he became the Cleric of Wroclaw. One year later he postulated to the office of Canon of Wrocław and Provost of Domasław, but he failed; however, this not discouraged Konrad IV, who by 1410 was finally chosen Canon of Wroclaw and during 1411-1417 held the office of Provost of the Chapter. In 1411 Konrad IV concentrated all his efforts to his election as Bishop of Warmia. To this end, he went even made the long journey to Rome, and although the expedition was unsuccessfully, as compensation he received with the master's degree and received a papal notary. In 1412 he was appointed Canon of Olomouc.
