Charles III (; 14 January 1823 – 27 March 1854) was the duke of Parma from 1849 to 1854.

He was the son of Duke Charles II of Parma and was educated in Saxony and Vienna. He grew up as a restless young man and traveled extensively while he was the hereditary prince of Lucca. For a time he served in the Piedmontese army with the rank of captain. In 1845, his father arranged his marriage with Princess Louise d'Artois, a wealthy heiress who gave him four children. In December 1847, at the death of Empress Marie Louise, his father became the reigning duke of Parma, but abdicated on 24 March 1849. Charles III became the duke of Parma, Piacenza and the Annexed States.

Charles III owed his throne to the support of Austrian troops. He placed Parma under martial law, inflicted heavy penalties on the members of the late provisional government, closed the university, and instituted a regular policy of persecution. His authoritarian policies made him unpopular. After reigning only five years, he was assassinated in March 1854.

Early life

Charles III was born at the Villa delle Pianore near Lucca on 14 January 1823, the son of Charles Louis, Prince of Lucca, (later Duke of Lucca, and Duke of Parma) and his wife Princess Maria Teresa of Savoy (daughter of King Victor Emmanuel I of Sardinia). He was given the baptismal names Ferdinando Carlo Vittorio Giuseppe Maria Baldassarre.

Marriage and issue

In 1845, as the duchy of Lucca was in great financial need, Ferdinando's father decided to marry him to a princess with a large dowry. The bride chosen was Princess Louise d'Artois (1819–1864), the only sister of the Legitimist pretender to the throne of France, the Comte de Chambord. She was the daughter of Charles Ferdinand, Duke of Berry and the granddaughter of King Charles X of France. Ferdinando Carlo, who was 22 years old at the time, was initially reluctant to marry her. She was four years older than him; she was his close relative; and he disliked the ideology of her entourage, the legitimist party. He would have rather waited three more years to marry, finding then a bride more of his liking. However, as his father threatened to cut his privy purse, leaving him completely destitute, Ferdinando ended up agreeing with the idea.

Ferdinando Carlo and Louise were cousins and they had known each other since they were children in Vienna. Their wedding took place on 10 November 1845 at Schloss Frohsdorff, Chambords's home in exile, near Lanzenkirchen in Austria, some 30 miles outside of Vienna. Their honeymoon took them to castle Urschendorff in Austria, and afterwards to England, a country where Ferdinand Carlo felt most at ease. The couple's married life was happy for some years. Their first child was born thirteen months after the wedding and three more children followed in quick succession: At this time he was described by a contemporary as "Tall and slim with an open and merry countenance, a light-hearted, light-headed, careless young man". a sister-in-law of the Austrian general governor of Trento. They met in Florence in February 1852, while Charles III was a guest of Leopold II, Grand Duke of Tuscany. In a semi-official visit to Queen Isabella II of Spain in December 1853, Charles III took his mistress with him, bringing about the final breakdown of his marriage.
