Middle Ages - John of Bohemia (Polish Opening: Czech Defence)

John the Blind (Luxembourgish: Jang de Blannen; German: Johann der Blinde von Luxemburg; Czech: Jan Lucemburský) (10 August 1296 – 26 August 1346) was the Count of Luxembourg from 1309 and King of Bohemia from 1310 and titular King of Poland. He was the eldest son of the Holy Roman Emperor Henry VII and his wife Margaret of Brabant. He is well known for having died while fighting in the Battle of Crécy at age 50, after having been blind for a decade. According to popular Czech saying, before he committed himself to combat in battle already lost, he said: "God forbid Bohemian king ever flees from fight". The sentence was pronounced in Czech: "Toho bohdá nebude, aby český král z boje utíkal".
