Michael Glinski

Michael Lvovich Glinski or Glinsky (; ; ; 1460s – 24 September 1534) was a noble from the Grand Duchy of Lithuania of distant Tatar extraction, who was also a tutor of his grand-nephew, Ivan the Terrible.

Glinski was born in Turov. He was a son of prince Lev Borisovich Glinski , and paternal uncle of Elena Glinskaya. As a young man, Glinski served in the court of Emperor Maximilian I and earned distinction for his military service. Around 1498 he returned to Lithuania and quickly rose in power and wealth, angering local nobles. Just after commanding the victorious Battle of Kletsk against the Crimean Khanate in August 1506, he was accused of conspiracy against the deceased Grand Duke Alexander Jagiellon and lost all his wealth. Glinski began an armed rebellion against Sigismund I, the new Grand Duke. The rebellion was unsuccessful and Glinsky retreated to the Grand Duchy of Moscow, where he served Vasili III of Russia. When the Muscovite–Lithuanian Wars renewed in 1512, Glinski was instrumental in helping Moscow to capture Smolensk, a major trading centre. However, he was not rewarded with the regency of the city. Angered, he planned to betray Vasili III, but the plot was discovered and he was imprisoned for 12 years. He was freed after his niece Elena Glinskaya, daughter of his brother Vasili Lvovich Glinski and Ana Jakšić, married Vasili III in 1526. Before his death in 1533, Vasili appointed Elena as regent for his underage sons Ivan and Yuri. Elena disapproved of Glinski's influence in state affairs and had him sent to prison, where he soon died of starvation.
