Siemomysl ²⁶⁰

  Notater:

Siemomysl or Ziemomysl (died c.950-960) was the third pagan Polans duke of the Piast dynasty, and the father of Poland's first Christian ruler, Mieszko I. He was listed by Gallus Anonymous in his Gesta principum Polonorum and was the son of Lestek, the second known Duke of the Polans. According to Gallus' account and historical research, Siemomysl has been credited with leaving the lands of Polans, Goplans and Masovians to his son Mieszko I, who further expanded them during his reign.

According to modern Polish historian Henryk Lowmianski, Siemomysl aided the Ukrani uprising against the Germans in 954 AD.

He supposedly reigned from around 930 (although some historians believe that he reigned from around 950). Siemomysl united the lands of Polanie, Goplanie, and Mazowszanie (however, some historians think that perhaps his father did it first). His burial place is unknown.

Siemomysl's wife (or wives) is unknown. There is a theory that Wlodzislaw's (prince of the Ledzianie tribe) daughter could have been Siemomysl's wife, but there is no historical evidence to support this. Formerly it was thought that his wife was named Gorka, but Oswald Balzer refuted this view in 1895.
