"Charles IV (Czech: Karel IV., German: Karl IV., Latin: Carolus IV; 14 May 1316 – 29 November 1378), born Wenceslaus, was the first King of Bohemia to become Holy Roman Emperor. He was a member of the House of Luxembourg from his father´s side and the Czech House of Přemyslid from his mother´s side; he emphasized the latter due to his lifelong affinity for the Czech side of his inheritance, and also because his direct ancestors in the Přemyslid line included two saints.
He was the eldest son and heir of King John of Bohemia, who died at the Battle of Crécy on 26 August 1346. His mother, Elizabeth of Bohemia, was the sister of King Wenceslas III, the last of the male Přemyslid rulers of Bohemia. Charles inherited the County of Luxembourg from his father and was elected king of the Kingdom of Bohemia. On 2 September 1347, Charles was crowned King of Bohemia." - (en.wikipedia.org 27.10.2019)
