Mieszko Mieszkowic Mieszko Mieszkowic Mieszko Mieszkowic (979/984 – aft. 992/95), was a Polish prince, and a member of the House of Piast. He was the second son of Mieszko I of Poland, but eldest born from Mieszko's second marriage to Oda, daughter of Dietrich of Haldensleben, Margrave of the North March. Little is known about his first years of life. Mieszko's first appearance is in the document ""Dagome iudex"" (ca. 991/92), along with his parents and brother Lambert. The purpose of the document was to protect Mieszko's and Lambert's inheritance from their older half-brother Bolesław I the Brave, who isn't named there.
Mieszko I of Poland took place on this occasion, the information on the return of the accord, acting for the good of the country and release of prisoners indicate that a conflict actually did occur. The marriage with Oda considerably affected the position and prestige of Mieszko, who entered the world of Saxon aristocracy. As a son-in-law of Margrave Dietrich, he gained an ally in one of the most influential politicians of the Holy Roman Empire. As the Margrave was a distant relative of the Emperor, Mieszko became a member of the circle connected to the imperial ruling house. Probably in the early 980s
