IOTL, King Denis of Portugal, over his 45 year reign, had only two legitimate children by his wife, Elizabeth of Aragon, a son, the future Alfonso IV, and a daughter, Constance, who married King Ferdinand IV of Castile.
When Denis died in 1325, Alfonso IV succeeded him and had issue. However, what if Alfonso had died sometime between his birth in 1291 and his marriage to Beatrice of Castile in 1309? Denis' legitimate heir would be his daughter, Constance. Depending on when Alfonso dies, how much resistance would there be to a union with the Kingdom of Castile? Would the Portuguese nobles accept Constance as Queen or would they support one of Denis' bastards?
Any thoughts?
