Through Holy Roman Empire

Francis was the oldest surviving son of Leopold, Duke of Lorraine, and the French princess Élisabeth Charlotte d'Orléans. Duke Leopold died in 1729 and was succeeded by his son. In 1736, Francis married Maria Theresa. In 1738, he left the Duchy of Lorraine and Bar for the deposed Polish king Stanisław Leszczyński in exchange for the Grand Duchy of Tuscany, as one of the terms ending the War of the Polish Succession. Following the death of his father-in-law, Charles VI, in 1740, Francis and Maria Theresa became the rulers of the Habsburg domains. Maria Theresa gave her husband responsibility for the empire's financial affairs, which he handled well. Francis died in 1765 and was succeeded by their son, Joseph II, who co-ruled Austria alongside Maria Theresa.

Early life

Francis was born in Lunéville, Lorraine (now in France), the fourth and oldest surviving son of Leopold, Duke of Lorraine, and his wife Princess Élisabeth Charlotte d'Orléans. He was connected with the Habsburgs through his grandmother Eleonore, daughter of Emperor Ferdinand III. He was very close to his brother Prince Charles Alexander of Lorraine and sister Princess Anne Charlotte of Lorraine.

Emperor Charles VI favoured the family, who, besides being his cousins, had served the house of Habsburg with distinction. He had designed to marry his daughter Maria Theresa to Francis' older brother Léopold Clément, Hereditary Prince of Lorraine. On Leopold Clement's death, Charles adopted the younger brother as his future son-in-law. Francis was brought up in Vienna with Maria Theresa with the understanding that they were to be married, and a real affection arose between them.

At the age of 15, when he was brought to Vienna, he was established in the Silesian Duchy of Teschen, which had been mediatised and granted to his father by the Emperor in 1722. Francis succeeded his father as Duke of Lorraine in 1729. In 1731 he was initiated into freemasonry (Grand Lodge of England) by John Theophilus Desaguliers at a specially convened lodge in The Hague at the house of the British Ambassador, Philip Stanhope, 4th Earl of Chesterfield. During a subsequent visit to England, Francis was made a Master Mason at another specially convened lodge at Houghton Hall, the Norfolk estate of British Prime Minister Robert Walpole.

Maria Theresa arranged for Francis to become "Lord Lieutenant" (locum tenens) of Hungary in 1732. He was not excited about this position, but Maria Theresa wanted him closer to her. In June 1732, he agreed to go to the Hungarian capital, Pressburg (today's Bratislava).

When the War of the Polish Succession broke out in 1733, France used it as an opportunity to seize Lorraine, since France's chief minister, Cardinal Fleury, was concerned that, as a Habsburg possession, it would bring Austrian power too close to France.

A preliminary peace was concluded in October 1735 and ratified in the Treaty of Vienna in November 1738. Under its terms, Stanisław I, the father-in-law of King Louis XV and the losing claimant to the Polish throne, received Lorraine, while Francis, in compensation for his loss, was made heir to the Grand Duchy of Tuscany, which he would inherit in 1737.

In March 1736, the Emperor persuaded Francis, his future son-in-law, to secretly exchange Lorraine for the Grand Duchy of Tuscany. France had demanded that Maria Theresa's fiancé surrender his ancestral Duchy of Lorraine to accommodate the deposed King of Poland. The Emperor considered other possibilities (such as marrying her to the future Charles III of Spain) before announcing the engagement of the couple. If something were to go wrong, Francis would become governor of the Austrian Netherlands.

Elisabeth of Parma had also wanted the Grand Duchy of Tuscany for her son Charles III of Spain; Gian Gastone de' Medici was childless and was related to Elisabeth via her great-grandmother Margherita de' Medici. As a result, Elisabeth's sons could claim by right of being a descendant of Margherita.

Although fighting stopped after the preliminary peace, the final peace settlement had to wait until the death of Gian Gastone in 1737 to allow the territorial exchanges provided for by the peace settlement to go into effect.

On 31 January 1736, Francis agreed to marry Maria Theresa. He hesitated three times (and laid down the feather before signing). Especially his mother Élisabeth Charlotte d'Orléans and his brother Prince Charles Alexander of Lorraine were against the loss of Lorraine. On 1 February, Maria Theresa sent Francis a letter: she would withdraw from her future reign when a male successor to her father appeared.
