St. Adalbert of Prague

Feast: April 23. The first bishop of Prague to have been born in Bohemia,
St. Adalbert was born Voytech c. 956 into a noble family. He was sent to
Magdeburg to be educated and took the name of his catechist when he was
baptized. After the death of his mentor in 981, Adalbert, who had grand visions
of missionary work and clerical reform, returned to Prague, and in the
following year, he became the second bishop of Prague. Conflict developed
between the bishop and the duke of Bohemia, Boleslaus II, and in 990, Adalbert
travelled to Rome, where he became a monk. John XV ordered him back to Prague
two years later, and Gregory V released him from his episcopal duties in 995,
after the massacre, at the order of Boleslaus, of Adalbert's family at Libice.
During these five years in Prague, Adalbert founded the abbey of Brevnov.
Boleslaus I, duke of Poland, invited him to evangelize the Prussians of
Pomerania; Adalbert was killed on the suspicion of being a Polish spy.
Boleslaus I buried Adalbert's body at Gniezno, Poland, whence it was translated
in 1039 to Prague. Adalbert was canonized in 999.
