With no living male heirs, Charles VI, Holy Roman Emperor, issues the Pragmatic Sanction of 1713 to ensure that Habsburg lands and the Austrian throne would be inherited by his daughter, Maria Theresa (not actually born until 1717).
The Pragmatic Sanction (Latin: Sanctio Pragmatica, German: Pragmatische Sanktion) was an edict issued by Charles VI, Holy Roman Emperor, on 19 April 1713 to ensure that the Habsburg hereditary possessions, which included the Archduchy of Austria, the Kingdom of Hungary, the Kingdom of Croatia, the Kingdom of Bohemia, the Duchy of Milan, the Kingdom of Naples, the Kingdom of Sardinia and the Austrian Netherlands, could be inherited by a daughter.
Charles and his wife Elizabeth Christine had not had children, and since 1711, Charles had been the sole surviving male member of the House of Habsburg. Charles's elder brother, Joseph I, had died without male issue, leaving Joseph's daughter Maria Josepha as the heir presumptive. That presented two problems. First, a prior agreement with his brother, known as the Mutual Pact of Succession (1703), had agreed that in the absence of male heirs, Joseph's daughters would take precedence over Charles's daughters in all Habsburg lands. Though Charles had no children, if he were to be survived by daughters alone, they would be cut out of the inheritance. Secondly, because Salic law precluded female inheritance, Charles VI needed to take extraordinary measures to avoid a protracted succession dispute, as other claimants would have surely contested a female inheritance.Charles VI was indeed ultimately succeeded by his own elder daughter, Maria Theresa (born 1717). However, despite the promulgation of the Pragmatic Sanction, her accession in 1740 resulted in the outbreak of the War of the Austrian Succession as Charles-Albert of Bavaria, backed by France, contested her inheritance. After the war, Maria Theresa's inheritance of the Habsburg lands was confirmed by the Treaty of Aix-la-Chapelle, and the election of her husband, Francis I, as Holy Roman Emperor was secured by the Treaty of Fssen.
Charles VI (German: Karl; Latin: Carolus; 1 October 1685 – 20 October 1740) was Holy Roman Emperor and ruler of the Austrian Habsburg Monarchy from 1711 until his death, succeeding his elder brother, Joseph I. He unsuccessfully claimed the throne of Spain following the death of his relative, Charles II. In 1708, he married Elisabeth Christine of Brunswick-Wolfenbüttel, by whom he had his four children: Leopold Johann (who died in infancy), Maria Theresa (the last direct Habsburg sovereign), Maria Anna (Governess of the Austrian Netherlands), and Maria Amalia (who also died in infancy).
Four years before the birth of Maria Theresa, faced with his lack of male heirs, Charles provided for a male-line succession failure with the Pragmatic Sanction of 1713. The Emperor favoured his own daughters over those of his elder brother and predecessor, Joseph I, in the succession, ignoring the decree he had signed during the reign of his father, Leopold I. Charles sought the other European powers' approval. They demanded significant terms, among which were that Austria close the Ostend Company. In total, Great Britain, France, Saxony-Poland, the Dutch Republic, Spain, Venice, States of the Church, Prussia, Russia, Denmark, Savoy-Sardinia, Bavaria, and the Diet of the Holy Roman Empire recognised the sanction. France, Spain, Saxony-Poland, Bavaria and Prussia later reneged. Charles died in 1740, sparking the War of the Austrian Succession, which plagued his successor, Maria Theresa, for eight years.
