When in 1138 the Seniorat of Poland was formed, Silesia was one of the Polish duchies and several Silesian duches were Seniors of Poland until the late 13th century. In the 12th and 13th centuries Silesia fall apart into several duchies of which Racibórz, OÅwiÄcim, Siewierz and Cieszyn as well as CzÄstochowa are in ÅlÄ skie. In the 14th centrury Siewierz and OÅwiÄcim again became a part of Poland, CzÄstochowa was also Polish, while Cieszyn and Racibórz came under Czech rule. Bohemia was ruled at this time by the German Luxembourg, later the Polish Jagiellonians and finally by the Austrian Habsburg. In 1741 Prussia annexed most of ÅlÄ skie, besides Cieszyn and CzÄstochowa.
