Konrad I of Oleśnica

Konrad I of Oleśnica (Polish: Konrad I oleśnicki) (c. 1294 – 22 December 1366) was a Duke of Żagań and Ścinawa during 1309–1312 (with his brothers as co-rulers), Duke of Oleśnica, Namysłów, Gniezno and Kalisz during 1312–1313 (with his brother as co-ruler), Duke of Kalisz during 1313–1314 (alone), Duke of Namysłów since 1313 (alone) and Duke of Oleśnica since 1321 until his death (alone).

He was the second son of Henry III (I), Duke of Głogów, by his wife Matilda, daughter of Albert I, Duke of Brunswick-Lüneburg.

After his father's early death in 1309, Konrad I succeeded him in all his lands with his brothers as co-rulers; but, because he was a minor at that time, he remained under the care of his mother and older brother Henry IV the Faithful until 1312.

Despite his minority, on 3 March 1310 in Berlin, Konrad I was present with his brothers Henry IV and Bolesław, when they solemnly renounced their rights over Gdańsk Pomerania to Brandenburg in exchange for a monetary compensation. In order to have good relations with the House of Ascania, they pledge the towns of Krosno Odrzańskie and Żagań to them (they will recover these territories in 1319).

On 29 February 1312, was made the formal division of the Duchy. Konrad I and Bolesław obtained as co-rulers the eastern part of the Duchy (Oleśnica, Namysłów and Kluczbork), and the regions of Kalisz and Gniezno. Henry IV, Jan and Przemko II retained the regions of Ścinawa, Żagań and Greater Poland. Their mother Matilda kept Głogów as her Oprawa wdowia. One year later, in 1313, Konrad I and Bolesław decided to divide their own domains: Konrad I received Namysłów and Kalisz.
