To clarify the Isabella Capet being refered to is the daughter of Phillip "The Fair" IV Capet, Wife to Edward II Plantagenet, and mother to Edward III Plantagenet.

Isabella was central to the uncovering of the Nesle Affair, Led a successful rebellion against her husband, reigned alongside her lover Roger Mortimer as regent for her son, and was all in all considered one of the most formidable female leaders of the time.

It is by claiming descent through Isabella that Edward III of England laid claim to France and to a large degree through her actions that the groundwork for the Hundred Years' War was laid.

So my question is this: What If Isabella Capet was born as the fourth son of Phillip IV rather than as his daughter?

Building on the assumption that Isabella has many of the same attributes that the female version had, how would she have acted?

Who would Edward II marry? Who would male-Isabella marry? What ramifications might these alternate marriages have?

Would something equivolent to the Nesle Affair happen?

How great of a possibility would there be for male-Isabella to become king?
