Poland during the Jagiellonian dynasty
Third Muscovite–Lithuanian WarLithuania
The Glinski rebellion was a revolt in 1508 in the Grand Duchy of Lithuania by a group of aristocrats led by Prince Mikhail Glinski in 1508. It grew out of a rivalry between two factions of the nobility during the final years of Grand Duke Alexander Jagiellon. The revolt began when Sigismund I, the new Grand Duke, decided to strip Glinski of his posts based on rumors spread by Jan Zabrzeziński, Glinski's personal enemy. After failing to settle the dispute at the royal court, Glinski and his supporters (mostly relatives) rose up in arms. The rebels swore allegiance to Vasili III of Russia, who was waging war against Lithuania.
The rebels and their Russian supporters failed to achieve military victory. They were allowed to go into exile in Moscow and take their movable property, but their vast land possessions were confiscated.
