By the middle of the 14th Century, a significant change
had come about in the loose arrangement of
representatives called to Parliament by the monarch.
Because they shared interests, the greater barons,
bishops, and abbots tended to draw together in a group -
while the knights tended to meet with citizens and
burgesses. From about 1330, the minor clergy, preferring
to meet in the ecclesiastical convocations of Canterbury and
York, dropped out altogether.
The remaining groups eventually divided into two assemblies - the House of Lords, consisting of people who were summoned to parliament as individuals; and the House of Commons, consisting of elected representatives.
