I want to know the answer to the following question:
Which two royals were part of the dynastic conflict of the 15th century?
All the background I'm provided with is that "Soon after, in the late 15th century, in the dynastic conflict between Isabella I of Castile and Joanna La Beltraneja, part of the Galician aristocracy supported Joanna.". Is that enough to answer the question?
Answer: yes
