In 1159, King Henry II of England tried to depose Count Raymond V of Toulouse (who supposedly had a weak claim to the county) by right of his wife, Eleanor, who had a claim to Toulouse via her grandmother, Philippa, the daughter and only legitimate child of Count William IV of Toulouse, the eldest son of Count Pons. In addition, the County of Toulouse was, at the time, nominally part of the Duchy of Aquitaine.
IOTL, Henry besieged the city but ultimately withdrew because his feudal lord, King Louis VII of France, was in the city at the time visiting Raymond, his brother-in-law. But what if Louis hadn't been in the Toulouse at the time? How long could Henry have held onto the County Toulouse, or even the city itself?
Any thoughts?
