John I, Count of Luxemburg.
'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,
King of Bohemia, and titular
King of Poland from
1310. He was the eldest son of the
Holy Roman Emperor Henry VII and his wife
Margaret of Brabant.
John was French by education, but deeply involved in the politics of Germany. In 1310, John married
Elisabeth, heiress of
Wenceslaus III of Bohemia, and thereby became King of Bohemia and so one of the seven
prince-electors of the Holy
Roman Empire. The object of the hostility of the Czech nobility, however, he gave up the administration of Bohemia and embarked on a life of travel, spending time in Luxembourg and the French court. His travels took him to
Silesia,
Poland,
Lithuania,
Tyrol,
Northern Italy,
Papal Avignon, and
Languedoc, where he was governor from
30 November 1338 to November
1340. He lost his eyesight from
ophthalmia, while crusading in
Lithuania with the
Teutonic order.
He retained his crown even after Elisabeth's death in
1330. His second wife was Beatrice, daughter of
Louis I, Duke of Bourbon.
He was killed whilst fighting alongside the French against the
English at the
Battle of Crécy, part of the
Hundred Years' War. The chronicler Froissart left the following account of John's last actions:
...for all that he was nigh blind, when he understood the order of the battle, he said to them about him: 'Where is the lord Charles my son?' His men said: 'Sir, we cannot tell; we think he be fighting.' Then he said: 'Sirs, ye are my men, my companions and friends in this journey: I require you bring me so far forward, that I may strike one stroke with my sword.' They said they would do his commandment, and to the intent that they should not lose him in the press, they tied all their reins of their bridles each to other and set the king before to accomplish his desire, and so they went on their enemies. The lord Charles of Bohemia his son, who wrote himself king of Almaine and bare the arms, he came in good order to the battle; but when he saw that the matter went awry on their party, he departed, I cannot tell you which way. The king his father was so far forward that he strake a stroke with his sword, yea and more than four, and fought valiantly and so did his company; and they adventured themselves so forward, that they were there all slain, and the next day they were found in the place about the king, and all their horses tied each to other.
After the battle, John's personal
crest (a pair of black wings) and motto ''Ich Dien'' ("I Serve") were adopted in slightly modified form by
Edward, the Black Prince, and since then they have been part of the
badge of the
Prince of Wales.
John was succeeded as King of Bohemia by his eldest son Charles (later
Charles IV, Holy Roman Emperor). In Luxembourg, he was succeeded by his son by his second wife,
Wenceslaus.
