Step-by-step explanation:
The main reason for Henry's initial difficulties as king can be attributed to his conflicts with religious and political factions in England. He faced opposition from nonconformists and was unable to work with Parliament, resulting in fiscal chaos and a weak position for England both domestically and internationally. Additionally, Charles's successor, James, being an avowed Catholic, inherited this divided and troubled country after Charles's death.
