Charles Brandon, 1st Duke of Suffolk, 1st Viscount Lisle, (22 August 1545) was an English military leader and courtier. Through his third wife, Mary Tudor, he was brother-in-law to King Henry VIII. Biography Charles Brandon was the second but only surviving son of Sir William Brandon, Henry Tudor's standard-bearer at the Battle of Bosworth Field, where Richard III was slain. His mother, Elizabeth Bruyn (d. March 1494), was daughter and co-heiress of Sir Henry Bruyn (died 1461). Charles Brandon was brought up at the court of Henry VII, and became Henry VIII's closest friend. He is described by Dugdale as "a person comely of stature, high of courage and conformity of disposition to King Henry VIII, with whom he became a great favourite." Brandon held a succession of offices in the royal household, becoming Master of the Horse in 1513, and received many valuable grants of land. On 15 May 1513, he was created Viscount Lisle, having entered into a marriage contract with his ward, Elizabeth Grey, suo jure Viscountess Lisle. The contract was ended and the title was forfeited as a result of Brandon's marriage to Mary Tudor in 1515. He distinguished himself at the sieges of Thérouanne and Tournai in the French campaign of 1513. One of the agents of Margaret of Savoy, governor of the Netherlands, writing from before Thérouanne, reminded her that Lord Lisle was a "second king" and advised her to write him a kind letter. At this time, Henry VIII was secretly urging Margaret to marry Lisle, whom he created Duke of Suffolk on 4 March 1514, although he was careful to disclaim any complicity in the project to her father, Maximilian I, Holy Roman Emperor. When Brandon was made Duke of Suffolk, he became only the third duke in the kingdom. After his marriage to Mary, Suffolk lived for some years in retirement, but he was present at the Field of the Cloth of Gold in 1520. In 1523 he was sent to Calais to command the English troops there. He invaded France in company with Floris d'Egmont, Count of Buren, who was at the head of the Flemish troops, and laid waste the north of France, but disbanded his troops at the approach of winter. Brandon was appointed Earl Marshal of England in 1524, a position previously held by Thomas Howard, 2nd Duke of Norfolk. However, in 1533 he relinquished the office
