Konrad I of Oleśnica

Konrad I (c. 1294–1366) was a Silesian Piast duke, the second son of Henry III of Głogów. After his father died in 1309 he ruled with his brothers, receiving Oleśnica in the 1312 partition and holding it alone after his brother Bolesław died in 1321.

He made peace at Kraków in 1323, surrendering Namysłów to end Polish and Legnica raids, and paid homage to John of Bohemia in 1328. He repelled Casimir III's invasion in 1343, gained Koźle in 1355 and a share of Bytom in 1357. He died in 1366.
