This action would prove a poor decision in the long term; Charles VII and his successors saw the Burgundian State as a serious impediment to the expansion of royal authority in France, and for this reason they would permanently try to undermine Burgundy, so as to subordinate it to French sovereignty. Philip's defection to the French would prove not only catastrophic to the dual monarchy of England and France, but to his own domains as well, subordinating them to a powerful centralised Valois monarchy.
