ใครแต่งงานกับFerdinando de' Medici, Grand Prince of Tuscany?

Ferdinando de' Medici (9 August 1663 – 31 October 1713) was the eldest son of Cosimo III de' Medici, Grand Duke of Tuscany, and Marguerite Louise d'Orléans. Ferdinando was heir to the Grand Duchy of Tuscany, with the title Grand Prince, from his father's accession in 1670 until his death in 1713. He is remembered today primarily as a patron of music. An excellent musician himself (sometimes called "the Orpheus of princes"), he attracted top musicians to Florence and thus made it an important musical center. Through his patronage of Bartolomeo Cristofori, Ferdinando made possible the invention of the piano.

Violante Beatrice of Bavaria (Violante Beatrix; 23 January 1673 – 30 May 1731) was Grand Princess of Tuscany as the wife of Ferdinando de' Medici, Grand Prince of Tuscany and Governor of Siena from 1717 until her death. Born a Duchess of Bavaria, the youngest child of Elector Ferdinand Maria, she married the heir to the Tuscan throne, Ferdinando de' Medici, in 1689. Violante Beatrice loved him but Ferdinando did not return her affection, declaring her too ugly and too dull. Her brother-in-law, Prince Gian Gastone, befriended her out of sympathy, a friendship that lasted until Violante Beatrice's demise.

Grand Prince Ferdinando died from syphilis in 1713, leaving his childless widow without purpose at the Tuscan court. Upon the return of the Electress Anna Maria Luisa de' Medici, daughter of the then reigning, Cosimo III, thus Violante Beatrice's sister-in-law, the Dowager Grand Princess contemplated retiring to her brother's court at Munich; however, Gian Gastone convinced her to stay, and Cosimo III appointed her Governor of Siena, where she then resided. As Governor, she formally defined the boundaries, names and number of Sienese Contrade — akin to administrative divisions — in 1729.

During Grand Duke Gian Gastone's rule, the Governor was responsible for formal court audiences. Violante Beatrice, in collaboration with the Electress Anna Maria Luisa, attempted to withdraw Gian Gastone from the Ruspanti, his salacious entourage, by arranging banquets and public appearances. Gian Gastone, however, was immune to these approaches and spent the last eight years of his reign confined to bed, entertained by the myriad Ruspanti.
