Richard II of England meets leaders of Peasants' Revolt on Blackheath. The Tower of London is stormed by rebels who enter without resistance.

The Peasants' Revolt, also named Wat Tyler's Rebellion or the Great Rising, was a major uprising across large parts of England in 1381. The revolt had various causes, including the socio-economic and political tensions generated by the Black Death in the 1340s, the high taxes resulting from the conflict with France during the Hundred Years' War, and instability within the local leadership of London.

The final trigger for the revolt was the intervention of a royal official, John Bampton, in Essex on 30 May 1381. His attempts to collect unpaid poll taxes in Brentwood ended in a violent confrontation, which rapidly spread across the south-east of the country. A wide spectrum of rural society, including many local artisans and village officials, rose up in protest, burning court records and opening the local gaols. The rebels sought a reduction in taxation, an end to serfdom, and the removal of King Richard II's senior officials and law courts.

Inspired by the sermons of the radical cleric John Ball and led by Wat Tyler, a contingent of Kentish rebels advanced on London. They were met at Blackheath by representatives of the royal government, who unsuccessfully attempted to persuade them to return home. King Richard, then aged 14, retreated to the safety of the Tower of London, but most of the royal forces were abroad or in northern England. On 13 June, the rebels entered London and, joined by many local townsfolk, attacked the gaols, destroyed the Savoy Palace, set fire to law books and buildings in the Temple, and killed anyone associated with the royal government. The following day, Richard met the rebels at Mile End and agreed to most of their demands, including the abolition of serfdom. Meanwhile, rebels entered the Tower of London, killing Simon Sudbury, Lord Chancellor, and Robert Hales, Lord High Treasurer, whom they found inside.

On 15 June, Richard left the city to meet Tyler and the rebels at Smithfield. Violence broke out, and Richard's party killed Tyler. Richard defused the tense situation long enough for London's mayor, William Walworth, to gather a militia from the city and disperse the rebel forces. Richard immediately began to re-establish order in London and rescinded his previous grants to the rebels. The revolt had also spread into East Anglia, where the University of Cambridge was attacked and many royal officials were killed. Unrest continued until the intervention of Henry Despenser, who defeated a rebel army at the Battle of North Walsham on 25 or 26 June. Troubles extended north to York, Beverley and Scarborough, and as far west as Bridgwater in Somerset. Richard mobilised 4,000 soldiers to restore order. Most of the rebel leaders were tracked down and executed; by November, at least 1,500 rebels had been killed.

The Peasants' Revolt has been widely studied by academics. Late 19th-century historians used a range of sources from contemporary chroniclers to assemble an account of the uprising, and these were supplemented in the 20th century by research using court records and local archives. Interpretations of the revolt have shifted over the years. It was once seen as a defining moment in English history, but modern academics are less certain of its impact on subsequent social and economic history. The revolt heavily influenced the course of the Hundred Years' War, by deterring later Parliaments from raising additional taxes to pay for military campaigns in France. The revolt has been widely used in socialist literature, including by the author William Morris, and remains a potent political symbol for the political left, informing the arguments surrounding the introduction of the Community Charge in the United Kingdom during the 1980s.

Richard II (6 January 1367 – c. 14 February 1400), also known as Richard of Bordeaux, was King of England from 1377 until he was deposed in 1399. He was the son of Edward, Prince of Wales (known to posterity as the Black Prince), and Joan, Countess of Kent. Richard's father died in 1376, leaving Richard as heir apparent to his grandfather, King Edward III. Upon the death of Edward III, the 10-year-old Richard succeeded to the throne.

During Richard's first years as king, government was in the hands of a series of regency councils, influenced by Richard's uncles John of Gaunt and Thomas of Woodstock. England then faced various problems, most notably the Hundred Years' War. A major challenge of the reign was the Peasants' Revolt in 1381, and the young king played a central part in the successful suppression of this crisis. Less warlike than either his father or grandfather, he sought to bring an end to the Hundred Years' War. A firm believer in the royal prerogative, Richard restrained the power of the aristocracy and relied on a private retinue for military protection instead. In contrast to his grandfather, Richard cultivated a refined atmosphere centred on art and culture at court, in which the king was an elevated figure.

The king's dependence on a small number of courtiers caused discontent among the influential, and in 1387 control of government was taken over by a group of aristocrats known as the Lords Appellant. By 1389 Richard had regained control, and for the next eight years governed in relative harmony with his former opponents. In 1397, he took his revenge on the Appellants, many of whom were executed or exiled. The next two years have been described by historians as Richard's "tyranny". In 1399, after John of Gaunt died, the king disinherited Gaunt's son, Henry Bolingbroke, who had previously been exiled. Henry invaded England in June 1399 with a small force that quickly grew in numbers. Meeting little resistance, he deposed Richard and had himself crowned king. Richard is thought to have been starved to death in captivity, although questions remain regarding his final fate.

Richard's posthumous reputation has been shaped to a large extent by William Shakespeare, whose play Richard II portrayed Richard's misrule and his deposition as responsible for the 15th-century Wars of the Roses. Modern historians do not accept this interpretation, while not exonerating Richard from responsibility for his own deposition. While probably not insane, as many historians of the 19th and 20th centuries believed, he may have had a personality disorder, particularly manifesting itself towards the end of his reign. Most authorities agree that his policies were not unrealistic or even entirely unprecedented, but that the way in which he carried them out was unacceptable to the political establishment, leading to his downfall.
