Anna Ioannovna (Анна Иоанновна; - ), also russified as Anna Ivanovna and sometimes anglicized as Anne, served as regent of the duchy of Courland from 1711 until 1730 and then ruled as Empress of Russia from 1730 to 1740. Much of her administration was defined or heavily influenced by actions set in motion by her uncle, Peter the Great ( 1682 - 1725), such as the lavish building projects in St. Petersburg, funding the Russian Academy of Science, and measures which generally favored the nobility, such as the repeal of a primogeniture law in 1730. In the West, Anna's reign was traditionally viewed as a continuation of the transition from the old Muscovy ways to the European court envisioned by Peter the Great. Within Russia, Anna's reign is often referred to as a "dark era". Anna was born in Moscow as the daughter of Tsar Ivan V by his wife Praskovia Saltykova. Ivan V was co-ruler of Russia along with his younger half-brother Peter the Great, but he was mentally disabled and reportedly had limited capacity of administering the country effectively, and Peter effectively ruled alone. Ivan V died in February 1696, when Anna was only three years old, and her half-uncle became the sole ruler of Russia. Although Anna was the fourth child of her parents, she had only one surviving elder sister, Catherine, and one younger sister, Praskovia. The three girls were raised in a disciplined and austere manner by their widowed mother, a stern lady of sterling character. Born into a family of relatively modest means, Praskovia Saltykova had been an exemplary wife to a mentally disabled man, and expected her daughters to live up to her own high standards of morality and virtue. Anna grew up within a milieu which cherished womanly virtue and domesticity above all else, and placed strong emphasis on thrift, charity and religious observances. Her education consisted of French, German, religious texts and folklore, leavened with some music and dancing. As she grew older, she developed into an obstinate girl, with a mean streak, earning her the nickname "Iv-anna the Terrible".
