The Three Musketeers
Also known as King Louis XIII. Although an important political figure in France, we don’t see much of the King in the novel. While Cardinal Richelieu oversees the Kingdom, the King pays attention to petty issues, like whether or not the Musketeers beat up the Cardinal’s Guards. During the siege of La Rochelle, he gets bored and requests permission from the Cardinal to take a vacation.
Historically, the King was known for being a very weak ruler. He was forced to marry Anne at the age of 14, which probably explains why their marriage wasn’t that great.
