The Wonderful Parliament met at Westminster Abbey to address King Richard II's need for money, but soon changed focus to the reform of his administration.

The Wonderful Parliament was a session of the English parliament held from October to November 1386 in Westminster Abbey. Originally called to address King Richard II's need for money, it quickly refocused on pressing for the reform of his administration. The King had become increasingly unpopular because of excessive patronage towards his political favourites combined with the unsuccessful prosecution of war in France. Further, there was a popular fear that England was soon to be invaded, as a French fleet had been gathering in Flanders for much of the year. Discontent with Richard peaked when he requested an unprecedented sum to raise an army with which to invade France. Instead of granting the King's request, the houses of the Lords and the Commons effectively united against him and his unpopular chancellor, Michael de la Pole, 1st Earl of Suffolk. Seeing de la Pole as both a favourite who had unfairly benefited from the King's largesse, and the minister responsible for the King's failures, parliament demanded the earl's impeachment.

Westminster Abbey, formally titled the Collegiate Church of Saint Peter at Westminster, is an Anglican church in the City of Westminster, London, England. Since 1066, it has been the location of the coronations of 40 English and British monarchs and a burial site for 18 English, Scottish, and British monarchs. At least 16 royal weddings have taken place at the abbey since 1100.

Richard II, 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, and Joan, Countess of Kent. Richard's father died in 1376, leaving Richard as heir apparent to his grandfather, King Edward III; upon the latter's death, the 10-year-old Richard succeeded to the throne.
