Overview
Konrad V Kantner (ca. 1385 – 10 September 1439) was a duke of Oleśnica, Koźle, half of Bytom and half of Ścinawa during 1412–1427 (with his brothers as co-rulers), since 1427 sole ruler over Oleśnica.
He was the second son of Konrad III the Old, Duke of Oleśnica, by his wife Judith. Like his one older and three younger brothers, at the baptism he received the name of Konrad, which was characteristic in this branch of the House of Piast. His nickname of Kantner was derived from the town of Kanth (pl: Kąty Wrocławskie), who was a property of the Oleśnica dukes since 1379.
Life
After the death of his father in 1412, Konrad V succeeded him in all his lands together with his older brother Konrad IV the Older as co-rulers, due to the minority of their younger brothers.
In 1416, when all Konrad III's sons attained his majority, Konrad IV renounced to the government on behalf of Konrad V and the rest of his brothers. However, because two other brothers (Konrad VI the Dean and Konrad VIII the Younger), also pursued a Church career, the main beneficiaries in the government are two others laic brothers: Konrad V and Konrad VII the White, who in 1431 co-founded in Koźle a Minorites Cloister. In 1434 they purchased the town of Wołczyn to Duke Louis II of Brieg. The co-rulership was maintained until 1427, when was made the division of the Duchy: Konrad V retained the main city of Oleśnica.
