and Robert de Vere, 9th Earl of Oxford, increasingly gained control of royal affairs. In a matter of three years, these councillors earned the mistrust of the Commons to the point that the councils were discontinued in 1380. Contributing to discontent was an increasingly heavy burden of taxation levied through three poll taxes between 1377 and 1381 that were spent on unsuccessful military expeditions on the continent. By 1381, there was a deep-felt resentment against the governing classes in the lower levels of English society. Early reign Peasants' Revolt Whereas the poll tax of 1381 was the spark of the Peasants' Revolt, the root of the conflict lay in tensions between peasants and landowners precipitated by the economic and demographic consequences of the Black Death and subsequent outbreaks of the plague. The rebellion started in Kent and Essex in late May, and on 12 June, bands of peasants gathered at Blackheath near London under the leaders Wat Tyler, John Ball, and Jack Straw. John of Gaunt's Savoy Palace was burnt down.

It is unclear how much Richard, who was still only fourteen years old, was involved in these deliberations, although historians have suggested that he was among the proponents of negotiations. The king set out by the River Thames on 13 June, but the large number of people thronging the banks at Greenwich made it impossible for him to land, forcing him to return to the Tower. The next day, Friday, 14 June, he set out by horse and met the rebels at Mile End. He agreed to the rebels' demands, but this move only emboldened them; they continued their looting and killings. Richard met Wat Tyler again the next day at Smithfield and reiterated that the demands would be met, but the rebel leader was not convinced of the king's sincerity. The king's men grew restive, an altercation broke out, and William Walworth, the Lord Mayor of London, pulled Tyler down from his horse and killed him. The situation became tense once the rebels realised
