Frederick, elector palatine (V.) and king of Bohemia, born in Amberg in 1596, died in Mentz, Nov. 19, 1032. He was the son of the elector Frederick IV., and by his mother grandson of William I. of Orange. He received a careful education, succeeded his father in the palatinate in 1010 as a minor, married Elizabeth, daughter of James I. of England, became the leader of the Protestant union, and in the second year of the thirty years' war (1619) was elected king of Bohemia by the revolted people. Induced by his ambitious wife, he accepted the regal crown, which he soon after lost through the battle of Prague (Nov. 8,1620), rapidly won by his cousin Maximilian of Bavaria, the head of the Catholic league. Frederick hastily escaped to Holland, and lived in exile, under the ban of the empire and persecuted by ridicule.
