Henry VI (1421–1471)

King of England from 1422, son of Henry V. He assumed royal power in 1442 and sided with the party opposed to the continuation of the Hundred Years' War with France. After his marriage in 1445, he was dominated by his wife, Margaret of Anjou. He was deposed in 1461 during the Wars of the Roses, was captured in 1465, temporarily restored in 1470, but again imprisoned in 1471 and then murdered.

Henry was eight months old when he succeeded to the English throne, and shortly afterwards, by the death in 1422 of his maternal grandfather, Charles VI, he became titular king of France. Unlike his father, Henry was disinclined to warfare, and when Joan of Arc revived French patriotism the English gradually began to lose their French possessions. By 1453 only Calais remained of his father's conquests.

The unpopularity of the government, especially after the loss of the English conquests in France, encouraged Richard, Duke of York, to claim the throne, and though York was killed in 1460, his son Edward IV proclaimed himself king in 1461.

Henry VI (1165–1197)

Holy Roman Emperor 1191–97. He conquered the Norman Kingdom of Sicily in the name of his wife, Constance, aunt and heiress of William II of Sicily, and was crowned at Palermo, Sicily, on Christmas Day, 1194. As part of his plan for making the empire universal, he captured and imprisoned Richard I of England and compelled him to do homage.

King Richard (I) the Lionheart of England was handed into Henry's power after falling into the hands of Duke Leopold of Austria when returning from crusade. Richard was released for a large ransom only after agreeing that England should become a fief of the Holy Roman Empire.
