Question: What were the differences between the Good Parliament and the Bad Parliament? Passage:Owing to Gaunt's influence, he was chosen in January 1376/7, in the last of Edward III's parliaments (the Bad Parliament), to act as Speaker of the House of Commons. According to the Rolls of Parliament (ii. 374) Hungerford "avait les paroles pur les communes d'Angleterre en cet parliament" ('[he] spoke for the commons of England in said Parliament'). He is thus the first person formally mentioned in the Rolls of Parliament as holding the office of speaker. Sir Peter de la Mare preceded him in the post, without the title, in the Good Parliament of 1376. In 1380 Hungerford was appointed Forester of Selwood. In 1369 he purchased from Walter Pavely, de jure Baron Burghersh, the manor of Farleigh Montfort, now called Farleigh Hungerford, which served as the chief residence of his descendants, and in 1383 obtained licence to crenellate his manor house there, which thus became Farleigh Castle. In about 1384 he aroused the suspicion of King Richard II, who attached him, but he obtained a pardon and also a confirmation of his free warren at Farleigh.
