Mazarinettes
The Mazarinettes were the seven nieces of Cardinal Jules Mazarin, the Chief Minister of France during the youth of King Louis XIV. He brought them, together with three of his nephews, from Italy to France in the years 1647 and 1653. Afterwards, he arranged advantageous marriages for them to powerful and influential French and Italian princes. To overcome aristocratic resistance to the matches, the cardinal generously granted huge dowries to the fiancés.
The girls were daughters of Mazarin's sisters, Laura Margherita and Geronima:
Laura Martinozzi (1635–1687), by marriage with Alfonso IV d'Este, Duchess of Modena and Reggio since 1658
Laura Mancini (1636–1657), by marriage with Louis de Bourbon, Duchess of Mercœur since 1651
Anne Marie Martinozzi (1637–1672), by marriage with Armand de Bourbon, Princess of Conti since 1654
Marie Mancini (1639–1715), by marriage with Lorenzo Onofrio Colonna, Princess Colonna since 1661
Olympia Mancini (1640–1708), by marriage with Eugène Maurice of Savoy, Countess of Soissons since 1657
