956 – Adalbert was born of a Czech noble family of Prince Slavnik in Libice nad Cidlinou, Bohemia.
980 – Adalbert finished his studies at Magdeburg school and returned to Prague where he became a priest.
982 – Adalbert became the Bishop of Prague. However, he strongly resented the participation of formally Christian inhabitants in the slave trade. Although Adalbert descended from a rich family and could afford comfort and luxury, he lived poorly of his own free will. He was noted for charity, austerity, and zealous service to the Church. His duty was difficult even in baptized Bohemia, as the pagan creed was deeply embedded in the peoples’ minds. Adalbert complained of polygamy and idolatry, which still were not unusual among the Czechs.
989 – Resigned from his bishop’s cloth and left Prague. He went to Rome and lived as a hermit in St. Alexis Benedictine monastery.
993 – The Pope sent him back to Bohemia. Adalbert became the Bishop again. That time he founded a monastery in Bøevnov, near Prague, the first one for men in the Czech lands. According to Cosmas’ chronicle, high clerical office was a burden to Adalbert.
997 – He was a bishop of Prague who was martyred in his efforts to convert the Baltic Prussians, to which he had been instigated by Polish King Boles³aw I the Brave. He was later made the patron saint of Bohemia, Poland, Hungary, and Prussia. He died on April 23, 997.
