Elena Glinskaya
Elena Vasilyevna Glinskaya (Russian: Елена Васильевна Глинская ; c. 1510 – 4 (13) April 1538, Moscow) was the second wife of Grand Prince Vasili III and regent of Russia for 5 years (1533–38).
Background
Elena was a daughter of Prince Vasili Lvovich Glinsky and Serb Princess Ana Jakšić. It is to her powerful uncle, Prince Mikhail Glinsky, that the family owed its distinction. In 1525, Vasili III resolved to divorce his barren wife, Solomoniya Saburova, and marry Elena. According to the chronicles, he chose Elena "because of the beauty of her face and her young age."
Grand Princess
Despite strong opposition from the Russian Orthodox Church, the divorce was effected, and Elena gave birth to Ivan (future Ivan IV the Terrible) in 1530 and Yuri (future prince of Uglich) in 1532. It was later rumoured, that Elena brought witches from Finland and people of the Sami to help her conceive by the help of magic On his deathbed, Vasili III transferred his powers to Elena Glinskaya until his oldest son Ivan was mature enough to rule the country. The chronicles of those times do not provide any more or less precise information on Elena's legal status after Vasili's death. All that is known is that it could be defined as regency and that the boyars had to report to her. That is why the time between Vasili's death on 3 December 1533 and her own demise in 1538 is called the reign of Elena.
