Unable to provide a viable candidate for the French throne (the League's support was split among several candidates, including Isabella, a Spanish princess, which made them appear to no longer have French interests at heart), the League's position weakened, but remained strong enough to keep Henry from besieging Paris.
Under the rule of King Henry IV, the Edict of Nantes was passed, granting religious toleration and limited autonomy to the Huguenots and ensuring a lasting peace for France.
