Mieszko I

Mieszko I ( Polish pronunciation: [ˈmjɛʂkɔ ˈpjɛrfʂɨ] ; c. 930 – 25 May 992) was Duke of Poland from 960 until his death in 992 and the founder of the first unified Polish state, the Civitas Schinesghe. A member of the Piast dynasty, he was the first Christian ruler of Poland and continued the policies of both his father and probably his grandfather, who initiated a process of unification among the Polish tribes and the creation of statehood.

According to existing sources, Mieszko I was a potent politician, a talented military leader and a charismatic ruler. Through both alliances and military force, he extended ongoing Polish conquests. Early in his reign, he subjugated Kuyavia and likely Gdańsk Pomerania and Masovia. For most of his reign, Mieszko I waged war for control of Western Pomerania. He eventually annexed it to the vicinity of the lower Oder River. His internal reforms were aimed at expanding and improving the so-called war monarchy system. During the last years of his life, he fought the Bohemian state and captured Silesia and lands now constituting Lesser Poland.
