Charles IV, also known as Charles of Luxembourg, born Wenceslaus, was Holy Roman Emperor from 1355 until his death in 1378. He was elected King of Germany in 1346 and became King of Bohemia that same year. He was a member of the House of Luxembourg from his father's side and the Bohemian House of Přemyslid from his mother's side; he emphasized the latter due to his lifelong affinity for the Bohemian side of his inheritance, and also because his direct ancestors in the Přemyslid line included two saints.
