Marie de Médicis was born on April 26, 1573 in Florence and died in July 3, 1642 in Cologne. Queen consort of King Henry IV of France (ruled 1589-1610) and from 1610 to1614, regent for her son, King Louis XIII (ruled 1610-43). She was the daughter of Francesco de’ Medici, grand duke of Tuscany, and Joanna of Austria. Shortly after Henry IV divorced his wife, Margaret, he married Mari (October 1600) in order to obtain a large dowry that would help him pay his debts. In 1601 Marie gave birth to the dauphin Louis (the future Louis XIII), and during the following eight years she bore the King five more children. Nevertheless, their relationship was strained. Marie resented Henry’s endless infidelities, and the King despised her unscrupulous Florentine favorites, Concino Concini and his wife Leonara. Upon the assassination of Henry IV (May 14, 1610) the Parliament of Paris proclaimed Marie regent for young King Louis XIII.
Guided by Concino (now the marquis d’ Ancre), Marie reversed Henry’s anti-Spanish policy. She squandered the state’s revenues and made humiliating concessions to the rebellious nobles. Although Louis XIII came of age to rule in September 1614, Marie and Ancre ignored him and continued to govern in his name. on April 24, 1617, Louis’s favorite, Charles d’ Albert de Luynes, had Ancre assassinated. Marie was then exiled to Blois, but in February 1619 she escaped and raised a revolt. Her principal adviser, the future Cardinal de Richelieu, negotiated the peace by which she was allowed to set up her court at Angers. Richelieu again won favorable terms for her after the defeat of her second rebellion (August 1620). Readmitted to the King’s council in 1622, Marie obtained a cardinal’s hat for Richelieu, and in August 1624 she persuaded Louis to make him chief minister. Richelieu, however, did not intend to be dominated by Marie. He enraged her by rejecting the Franco-Spanish alliance and allying France with Protestant powers. By 1628 Marie was the Cardinal’s worst enemy. In the crisis known as the Day of the Dupes (Nov. 10, 1630), she demanded that Louis dismiss the minister. Louis stood by Richelieu and in February 1631 banished Marie to Compiègne. She fled to Brussels in the Spanish Netherlands in July 1631 and never returned to France. Eleven years later she died destitute.
Marie de Médicis build the Luxembourg Palace in Paris, and in 1622-24 the Flemish artist Peter Paul Rubens decorated its galleries with 21 paintings, portraying the events of her life, that rank among his finest work. – The New Encyclopedia Britannica
