Thomas of Lancaster, 1st Duke of Clarence

1387–1421

Thomas of Lancaster, Duke of Clarence, was the second surviving son of Henry IV and a younger brother of Henry V. He served as a military commander and royal lieutenant in France, helping to maintain Lancastrian power during the later phases of the Hundred Years’ War.

In 1421 he led an impetuous attack at Baugé and was killed, a serious blow to the English war effort. Thomas of Lancaster, 1st Duke of Clarence was born in Kenilworth Castle and died in Baugé.

Georgette Heyer’s My Lord John places Thomas of Lancaster inside the royal household in which his younger brother John of Bedford is raised. As one of Henry IV’s sons, Clarence belongs to a generation expected to turn dynastic legitimacy into military service, and his presence helps the novel show how the Lancastrian princes were trained for command and drawn into the wars sustaining their father’s crown.
