Adalbert of Prague, known in the Czech Republic, Poland and Slovakia by his birth name Vojtěch, was a Czech missionary and Christian saint. He was the Bishop of Prague and a missionary to the Hungarians, Poles, and Prussians, who was martyred in his efforts to convert the Baltic Prussians to Christianity. He is said to be the composer of the oldest Czech hymn Hospodine, pomiluj ny and Bogurodzica, the oldest known Polish hymn, but his authorship of them has not been confirmed.
