Frederick V of the Palatinate, born in 1596, was a German prince and the Elector Palatine of the Rhine. He is best known for his brief reign as King of Bohemia from 1619 to 1620, during which he was a key figure in the early stages of the Thirty Years' War. His rule was marked by his attempt to establish Protestantism in a predominantly Catholic region. Frederick was married to Elizabeth Stuart, the daughter of James I of England, which strengthened ties between England and the Palatinate. After his defeat at the Battle of White Mountain in 1620, he lost his throne and went into exile, living in the Netherlands until his death in 1632.
