Yorkist: 7,000-15,000; Lancastrian: 10,000-30,000 (sources vary)
The Battle of Barnet was a decisive Yorkist victory in the Wars of the Roses, a dynastic conflict of 15th-century England. The military action, along with the subsequent Battle of Tewkesbury, secured the throne for Edward IV.
On Sunday 14 April 1471, Easter Day, near Barnet, then a small Hertfordshire town north of London, Edward led the House of York in a fight against the House of Lancaster, which backed Henry VI for the throne. Leading the Lancastrian army was Richard Neville, Earl of Warwick, who played a crucial role in the fate of each king. Historians regard the battle as one of the most important clashes in the Wars of the Roses, since it brought about a decisive turn in the fortunes of the two houses. Edward's victory was followed by 14 years of Yorkist rule over England.
Formerly a key figure in the Yorkist cause, Warwick defected to the Lancastrians over disagreements about Edward's nepotism, secret marriage, and foreign policy. Leading a Lancastrian army, the earl defeated his former allies, forcing Edward to flee to Burgundy in October 1470. The Yorkist king persuaded his host, Charles the Bold, the Duke of Burgundy, to help him regain the English throne. Leading an army raised with Burgundian money, Edward launched his invasion of England, which culminated at the fields north of Barnet. Under cover of darkness, the Yorkists moved close to the Lancastrians and clashed in a thick fog at dawn. As both armies fought, the Earl of Oxford on the Lancastrian right routed the Yorkists opposite under Lord Hastings, chasing them back to Barnet. On their return to the battlefield, Oxford's men were erroneously shot at by the Lancastrian centre commanded by Lord Montagu. As cries of treason (always a possibility in that chaotic period) spread through their line, Lancastrian morale was disrupted and many abandoned the fight. While retreating, Warwick was killed by Yorkist soldiers.
Warwick had been such an influential figure in 15th-century English politics that, on his death, no one matched him in terms of power and popularity. Deprived of Warwick's support, the Lancastrians suffered their final defeat at the Battle of Tewkesbury on 4 May, which marked the end of the reign of Henry VI and the restoration of the House of York. Three centuries after the Battle of Barnet, a stone obelisk was raised on the spot where Warwick purportedly died.
The Wars of the Roses were a series of conflicts between various English lords and nobles in support of two different royal families descended from Edward III. In 1461 the conflict reached a milestone when the House of York supplanted its rival, the House of Lancaster, as the ruling royal house in England. Edward IV, leader of the Yorkists, seized the throne from the Lancastrian king, Henry VI, who was captured in 1465 and imprisoned in the Tower of London. His wife, Margaret of Anjou, and their son, Edward of Westminster, fled to Scotland and organised resistance. Edward IV crushed the uprisings and pressured the Scottish government to force Margaret out; the House of Lancaster went into exile in France. As the Yorkists tightened their hold over England, Edward rewarded his supporters, including his chief adviser, Richard Neville, 16th Earl of Warwick, elevating them to higher titles and awarding them land confiscated from their defeated foes. The Earl grew to disapprove of the King's rule, however, and their relationship later became strained.
