Grand Duchess Anna Leopoldovna, née Elisabeth Katharina Christine (1718–1746), was the daughter of Duke Karl Leopold of Mecklenburg-Schwerin and Tsarevna Catherine Ivanovna, who was the daughter of Tsar Ivan V Alexeyevich. Anna was the niece of Empress Anna Ioannovna. She married Duke Anthony Ulrich of Brunswick-Luneburg in 1739 and gave birth to Ivan Antonovich, the heir to the throne, in 1740. After the death of Anna Ioannovna and the dismissal of Biron, who had been appointed regent, she herself became regent for the infant Emperor Ivan VI on 9 November 1740. Following a palace coup on 25 November 1741 she and her son were overthrown and sent into exile, where she died in 1746.
Ioann Antonovich spent the rest of his life in confinement (in the fortress of Shlisselburg from 1756). He was killed by guards on 5 July 1764 during an attempt to liberate him organised by Vasily Mirovich, an officer of the guard.
