In 1461 England was in the sixth year of the Wars of the Roses, a series of civil wars between the houses of York and Lancaster over the English throne. The Lancastrians backed the reigning King of England, Henry VI, an indecisive man who had bouts of madness. The leader of the Yorkists was initially Richard, Duke of York, who resented the dominance of a small number of aristocrats favoured by the king, principally his close relatives, the Beaufort family. Fuelled by rivalries between influential supporters of both factions, York's attempts to displace Henry's favourites from power led to war. After capturing Henry at the Battle of Northampton in 1460, the duke, who was of royal blood, issued his claim to the throne. Even York's closest supporters among the nobility were reluctant to usurp the dynasty; the nobles passed by a majority vote the Act of Accord, which ruled that the duke and his heirs would succeed to the throne upon Henry's death.
