Przemyslaus I Noszak, Duke of Cieszyn

Przemysław I Noszak (Polish: Przemysław I Noszak, Czech: Přemyslav I. Nošák, German: Przemislaus I. von Teschen; 1332/1336 – 23 May 1410), was a Duke of Cieszyn-Bytom-Siewierz from 1358 (during 1359–1368 he lost Siewierz and in 1405 also lost Bytom), from 1384 ruler over half of both Głogów and Ścinawa (except during 1404–1406) and since 1401 ruler over Toszek.

He was the third son of Casimir I, Duke of Cieszyn, by his wife Euphemia, daughter of Duke Trojden I of Czersk-Warsaw.

At first, it seemed that Przemysław had no better chance of getting any part of his father's inheritance; however, the early deaths of his older brothers Władysław (in 1355) and Bolesław (in 1356) made him the main heir of Duke Casimir I.

From 1355 Przemysław began his political life at the court of Emperor Charles IV, where a year later he received the dignity of court judge after the death of his brother Władysław. After his father's death in 1358 he took full control over Cieszyn, without interrupting his diplomatic career.

His marriage to Elisabeth, daughter of Bolesław, Duke of Koźle-Bytom in 1360 give him additional rights over the half of Bytom taken by his father Casimir I in 1357. The dispute over these lands with the Dukes of Oleśnica was definitely resolved in 1358. Casimir I remained as legal guardian over the three daughters of the late Duke of Bytom —Elisabeth (Przemysław's future wife), Euphemia and Bolka—, who had to renounce all their claims over half of Bytom and Koźle, so the Dukes of Cieszyn took almost the whole inheritance of Duke Bolesław (except Koźle and half of Bytom, which was taken by the Dukes of Oleśnica). Unfortunately, the acquisition of Bytom didn't last.
