a.k.a States–General a.k.a. French Parliament
King Philip IV of France convenes first Estates–General – as a consequence of his (Philip the Fair’s) dispute with the (somewhat overbearing) Pope Boniface VII (just noted above).
All three “estates” are present for the first time –
“First Estate” – the Clergy
“Second Estate” – the Nobility
“Third Estate” – commoners*
* Initially these “commoners” were only from bonnes villes – privileged towns, and in any event, had miniscule power at the Estates–General.
