Charles VI was the Holy Roman Emperor from 1711 until his death in 1740. He was a member of the Habsburg dynasty and is best known for his efforts to secure the succession of his daughter, Maria Theresa, to the throne. To ensure her claim, he issued the Pragmatic Sanction in 1713, which aimed to unify the Habsburg lands under her rule. During his reign, Charles VI faced various challenges, including military conflicts and political rivalries. His death in 1740 led to the War of the Austrian Succession, as many European powers contested Maria Theresa's right to inherit the Habsburg territories.
