The Good Parliament is the name traditionally given to the English Parliament of 1376. Sitting in London from April 28 to July 10, it was the longest Parliament up until that time. It took place during a time when the English court was perceived by much of the English population to be corrupt, and its traditional name was due to the sincere efforts by its members to reform the government. It had a formidable enemy, however, in John of Gaunt, fourth son of Edward III and the effective ruler of England at the time.
