West Pomeranian Voivodeship in the context of "Słupsk Voivodeship"

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 Siemomysł and his grandfather Lestek, 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.

Pomerania (Polish: Pomorze [pɔˈmɔʐɛ] ; German: Pommern [ˈpɔmɐn] ; Kashubian: Pòmòrskô; Swedish: Pommern) is a historical region on the southern shore of the Baltic Sea in Central Europe, split between Poland and Germany. The central and eastern part belongs to the West Pomeranian, Pomeranian and Kuyavian-Pomeranian voivodeships of Poland, while the western part belongs to the German states of Mecklenburg-Western Pomerania and Brandenburg.

Pomerania's historical border in the west is the Mecklenburg-Western Pomeranian border Urstromtal, which now constitutes the border between the Mecklenburgian and Pomeranian part of Mecklenburg-Western Pomerania, while it is bounded by the Vistula River in the east. The easternmost part of Pomerania is alternatively known as Pomerelia, consisting of four sub-regions: Kashubia inhabited by ethnic Kashubians, Kociewie, Tuchola Forest and Chełmno Land.

Greater Poland Voivodeship (Polish: województwo wielkopolskie [vɔjɛˈvut͡stfɔ vjɛlkɔˈpɔlskʲɛ] ) is a voivodeship, or province, in west-central Poland.
