Union of Aquitaine and Brittany
In 1623, Navarre became independent. The Navarrese nobles wished to elect one of themselves but, after rough persuasion, accepted Henry II as their king; a younger cousin of Duke Geoffrey III, forcing Henry to renounce his claim on the Aquitanian throne on behalf of himself and his descendants.
Fall in Aquitaine
After the dissolution of the Aquitanian realm, brought about by Castille and the HRE, the House of Foix maintained rule over Birttany, Anjou, Bordeaux, Navarre and Aquitaine. Intending to rebuild their former glory, the annexed their former territories, creating a French Union.
However, the death of Duchess Mary II prompted her husband, about to be deprived of rule according to the will of the late Duchess, who named her sister Elisabeth as her successor, dissolved the French Union and created a French Republic, centered around Paris.
The new republic was ruled by the Vienne family, headed by Charles de Vienne, former husband of Mary II and named Chancellor of France. The Vienne family ruled until their deposition and the Bourbonnais family, descendants of Elisabeth, were put on the throne.
