Mieszko I

Lore & Background

Mieszko I took over rule after his father's death c. 950–960, inheriting lands inhabited by the Polans and Goplans, as well as the Sieradz-Łęczyca lands and Kuyavia, and possibly Masovia and Gdańsk Pomerania. Early in his reign, he subjugated Kuyavia and likely Gdańsk Pomerania and Masovia. He waged war for control of Western Pomerania for most of his reign, eventually annexing it to the vicinity of the lower Oder River. His internal reforms aimed at expanding and improving the war monarchy system. In his last years, he fought the Bohemian state and captured Silesia and lands now constituting Lesser Poland.

Reader's Guide

Mieszko I's significance lies in founding the first unified Polish state and introducing Christianity to Poland through his baptism in 966, which placed his country in the cultural sphere of Western Christianity. He is sometimes called the 'Clovis of Poland' for laying the foundations for a Christian Poland. Through diplomacy, he formed alliances with Bohemia, Sweden, and the Holy Roman Empire, and his marriage to the Přemyslid princess Dobrawa strengthened ties with Bohemia. On his death, he left his son Bolesław I the Brave a country with greatly expanded territories and a well-established position in Europe. His appearance as 'Dagome' in the papal document Dagome iudex suggests a gift of his land to the Pope. Through his daughter, he became grandfather of Canute the Great and great-grandfather of Gunhilda of Denmark.
