Charles I

Charles I is one of the most instantly recognizable of the English monarchs. During his reign the relationship between king and Parliament changed radically, with revolutionary results. A man of deeply held convictions whose refusal to compromise brought about conflict and civil war, King Charles I almost destroyed the English monarchy forever.
When considering the 24-year reign of Charles I, it is difficult not to come to the conclusion that he may have made a much better Duke of York (the title historically given to the second son of the royal family) than King of England. And perhaps Charles, too, would have been much happier had his older brother taken the throne instead.
