Where and by whom might french royal power be challenged after 1328?

The French royal power could be questioned because: after the death of Charles IV of France in 1328 there was no male heirs and that ended the main Capetian line. Under Salic law the crown could not pass through a woman (Philip IV's daughter was Isabella, whose son was Edward III of England), so the throne passed to Philip VI, son of Charles of Valois. This, in addition to a long-standing dispute over the rights to Gascony in the south of France, and the relationship between England and the Flemish cloth towns, led to the Hundred Years' War of 1337–1453. The following century was to see devastating warfare, peasant revolts (the English peasants' revolt of 1381 and the Jacquerie of 1358 in France) and the growth of nationalism in both countries.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.  

because it’s really sad that’s why it’s in history native americans getting kicked out of their homeland.
