Louis XIII of France
Louis XIII (sometimes called the Just; 27 September 1601 – 14 May 1643) was King of France from 1610 to 1643 and King of Navarre (as Louis II) from 1610 to 1620, when the crown of Navarre was merged with the French crown.
Shortly before his ninth birthday, Louis became king of France and Navarre after his father Henry IV was assassinated.
His mother, Marie de' Medici, acted as regent during his minority.
Mismanagement of the kingdom and ceaseless political intrigues by Marie and her Italian favourites led the young king to take power in 1617 by exiling his mother and executing her followers, including Concino Concini, the most influential Italian at the French court.
Louis XIII, taciturn and suspicious, relied heavily on his chief ministers, first Charles d'Albert, duc de Luynes and then Cardinal Richelieu, to govern the Kingdom of France.
King and cardinal are remembered for establishing the "Académie française", and ending the revolt of the French nobility.
They systematically destroyed the castles of defiant lords, and denounced the use of private violence (dueling, carrying weapons, and maintaining private armies).
By the end of the 1620s, Richelieu had established "the royal monopoly of force" as the ruling doctrine.
His reign was also marked by the struggles against the Huguenots and Habsburg Spain.

During the reign of his brother he was known simply as "Monsieur", the traditional style at the court of France for the younger brother of the king.
Although he was open about his homosexual behaviour and freely acted effeminately, he married twice and fathered several children.
He was the founder of the House of Orléans, a cadet branch of the ruling House of Bourbon, and thus the direct ancestor of Louis Philippe I, who ruled France from 1830 until 1848 in the July Monarchy.
Through the children of his two marriages, Philippe became an ancestor of most modern-day Roman Catholic royalty, giving him the nickname of "the grandfather of Europe".
