Archduchess Maria Anna Eleonore Wilhelmine Josepha of Austria (18 September 1718 – 16 December 1744) was a member of the House of Habsburg who governed the Austrian Netherlands in the name of her elder sister, Empress Maria Theresa.
In 1725, negotiations with the Queen of Spain, Elisabeth Farnese had Maria Anna as a possible wife of Philip, Duke of Parma, who was just five. This match was supposed to smooth over relations with Spain. An alliance of Spain and Austria was signed on 30 April 1725 and thus guaranteed the Pragmatic Sanction of 1713, allowing Maria Theresa right of her father's lands being his eldest daughter. Based on the terms of the treaty, the Habsburg monarchy relinquished all claims to the Spanish throne. It also agreed that Spain would invade Gibraltar with the help of the Austrians. Despite this, the Anglo-Spanish War stopped the ambitions of Elisabeth of Parma and with the signing of the Treaty of Seville (9 November 1729) saw the abandonment of the Austro-Spanish marriage plans.
She fell in love with Charles Alexander of Lorraine, the younger brother of Maria Theresa's husband, Francis Stephen. There was considerable resistance to their marriage, not least the wish of her father for a politically more important son-in-law.
It was only after their father's death that Empress Elisabeth Christine gave the approval for the marriage, which was concluded in the Augustinian Church, Vienna on 7 January 1744. The marriage was recognised by letters patent signed on 8 January.
Weeks after the marriage, the couple was appointed governors of the Austrian Netherlands in succession of their aunt Archduchess Maria Elisabeth of Austria, who had died in 1741. The couple left Vienna on 3 February and arrived in Wuustwezel, a town in the Austrian Netherlands, on 24 March where they were met by Count Karl Ferdinand von Königsegg-Erps. Karl Ferdinand was a member of the Supreme council of the Netherlands and had to receive Prince Charles and Maria Anna due to etiquette. Their arrival was greeted with much celebration. A ceremony had been organised for their arrival; this included a Te Deum and a collection of balls and banquets.
The couple only had two months of time together in the Netherlands, as Charles had to leave to participate in the war against Prussia, while Maria Anna, pregnant with their first child, remained in Brussels. Charles left officially on 4 May.
On 9 October 1744 Maria Anna went into labour and gave birth to a stillborn daughter; she never recovered and died 16 December 1744 as after-effect to the difficult childbirth. She and her daughter were buried in the Imperial Crypt in Vienna. Charles Alexander never remarried, and would remain the governor until his death in 1780. He was a very popular governor and died in Brussels like his wife.
Generations are numbered by male-line descent from Frederick III, Holy Roman Emperor. Later generations are included although Austrian titles of nobility were abolished and outlawed in 1919.
