Adalbert of Prague
Commemorates Saint Adalbert of Prague, a 10th-century bishop and missionary who brought Christianity to Central Europe.
Saint Adalbert of Prague (c. 956–997) was the bishop of Prague and a pioneering missionary among the Baltic Prussians. Born into Bohemian nobility, he studied theology in Magdeburg and Rome before returning to his homeland to lead the church. Conflicts with local rulers led him to resign and undertake missionary journeys to Poland and the Prussian regions. He was martyred near the Baltic Sea and his courage inspired the Christianization of Central Europe. Canonized in 999, his relics became enshrined in Gniezno, where he is celebrated for his faith and leadership.
