In England Edward shaped the Constitution and settled for future times the lines of Parliamentary representative government.
EDWARD I.'S MODEL PARLIAMENT, 1295 For the first twenty years Edward's Parliaments were great assemblies of barons and knights, and it was not till 1295 that the famous Model Parliament was summoned.

"It is very evident that common dangers must be met by measures concerted in common," ran the writ to the bishops.

Every sheriff was to cause two knights to be elected from each shire, two citizens from each city, two burgesses from each borough.

The clergy were to be fully represented from each cathedral and each diocese.
Hitherto Parliament, save in 1265, had been little else than a feudal court, a council of the King's tenants; it became, after 1295, a national assembly.

Edward's plan was that the three estates--clergy, barons, and commons: those who pray, those who fight, and those who work--should be represented.
