Edward I's succession remained fragile despite his forceful kingship. Edward and Eleanor of Castile had at least fourteen children, yet only the future Edward II among their sons survived his father. The discussion pauses over John, Henry, and Alfonso because each would have inherited in his thirties or forties had he lived to 1307. In this interpretation, those older heirs would also have gained reputations and military experience during Edward I's wars. Edward II instead succeeds at twenty-three, much younger than the brothers who might have preceded him. The family list demonstrates that prolific marriage could produce alliances and heirs without guaranteeing the mature successor on whom a political system depended.

Edward I's succession luck runs out
Edward and Eleanor of Castile had many children, yet the deaths of John, Henry, and Alfonso left the much younger Edward II as the only son to outlive his father.
