John Beaufort, Marquess of Dorset and "Earl of Dorset", courtesy titles granted to the Beaufort heir-apparent or heir-presumptive. These titles were not recognized by King Edward IV, of the House of York. John had been in exile since 1461, first in Burgundy and then France. When Henry VI of Lancaster reclaimed the throne in October 1470, John returned with his brother Edmund. But a few months later, Henry was driven from the throne again, and the Lancastrians were on the run. John was killed in the Battle of Tewkesbury on 4 May 1471, while fighting beside Edmund, who was captured and beheaded two days later.
