King Charles I faces the escalating political and religious tensions of 17th-century England that threaten to dismantle his monarchy. Caught between the rigid demands of Parliament and his own belief in the divine right of kings, Charles struggles to maintain control over a fracturing nation. The narrative follows his personal and political decline as he navigates shifting loyalties, military conflict, and the eventual collapse of his authority.
