The Parliament of 1327, which was instrumental in the transfer of the English Crown from King Edward II to his son, Edward III, began at the Palace of Westminster.

The Parliament of 1327, which sat at the Palace of Westminster between 7 January and 9 March 1327, was instrumental in the transfer of the English Crown from King Edward II to his son, Edward III. Edward II had become increasingly unpopular with the English nobility due to the excessive influence of unpopular court favourites, the patronage he accorded them, and his perceived ill-treatment of the nobility. By 1325, even his wife, Queen Isabella, despised him. Towards the end of the year, she took the young Edward to her native France, where she entered into an alliance with the powerful and wealthy nobleman Roger Mortimer, who her husband previously had exiled. The following year, they invaded England to depose Edward II. Almost immediately, the King's resistance was beset by betrayal, and he eventually abandoned London and fled west, probably to raise an army in Wales or Ireland. He was soon captured and imprisoned.

The Crown is a political concept used in Commonwealth realms, analogous to the concept of the state in legal systems influenced by Roman civil law.

Edward II, also known as Edward of Caernarfon or Caernarvon, was King of England from 1307 until he was deposed in January 1327. The fourth son of Edward I, Edward became the heir to the throne following the death of his older brother Alphonso. Beginning in 1300, Edward accompanied his father on campaigns in Scotland, and in 1306 he was knighted in a grand ceremony at Westminster Abbey. Edward succeeded to the throne the next year, following his father's death. In 1308, he married Isabella, daughter of the powerful King Philip IV of France, as part of a long-running effort to resolve the tensions between the English and French crowns.

Edward III, also known as Edward of Windsor before his accession, was King of England from January 1327 until his death in 1377. He is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign is one of the longest in English history, and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death. He outlived his eldest son, Edward the Black Prince, and was succeeded by his grandson, Richard II.
