Coat of arms of the City of London 13th-century seal, and on two embroidered seal-bags of 1319, that depicted St Paul holding a sword. It is sometimes said that the sword in the 1381 arms represents the dagger used by Lord Mayor of London William Walworth to kill Wat Tyler, leader of the Peasants' Revolt, on 15 June 1381. This tradition dates at least as far back as the first edition of "Holinshed's Chronicles", published in 1577, but cannot be correct, as the arms were in use some months before Tyler's death. The crest and supporters came into use in the 17th century, but were used without authority
Peasants' Revolt until the intervention of Henry le 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
