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 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.
Origin and progress
Historical background
In the early 16th century, the Grand Duchy of Lithuania lost about one-third of its territory as a result of the second war with Muscovy from 1500 to 1503.
In addition, there were internal disagreements over a new union with the Kingdom of Poland (1501). To take effect, the Union of Mielnik needed to be ratified by the Lithuanian Seimas. Opponents of the union, among them Mikhail Glinski and the Grand Duke Alexander, refused to approve the union during the 1505 Seimas in Brest. Supporters of the union wanted to expand their political rights; the union greatly limited the power of the monarchy and in Poland led to the elective monarchy.
In February 1507, the Seimas in Vilnius decided to demand the return of the territory it had lost in the previous war with Muscovy, and dispatched an ambassador to Moscow with an ultimatum. The ambassador's failure was regarded as casus belli. Moscow acted first but, despite a delay in mustering the Lithuanian troops, did not achieve any significant results. Military actions in the first phase of the war (prior to the entry of the rebels into the conflict) were rather passive and did not bring about a desired result for either of the parties.
Causes
During the last years of Grand Duke Alexander's reign, Mikhail Glinski wielded considerable influence at court, and held the important post of Court Marshal from 1500 to 1506. The rapid growth of Glinski's influence troubled the old Lithuanian aristocracy, such as the Radziwiłł family, the Kęsgailos, and especially Jan Zabrzeziński, who became Glinski's personal enemy. As a trustee of the Grand Duke, Glinski facilitated the rise of his relatives and of others, which strengthened his position.
The ambassador of the German emperor, Sigismund von Herberstein, set out the essence of the rebellion in his Notes on Muscovite Affairs. The cause of the quarrel between Glinski and Zabrzeziński, he thought, was that Trakai voivode Zabrzeziński had ordered to beat Glinski's servant because the servant was sent for a second time to get oats for the royal horses in Trakai. Glinski, who had great influence on the Grand Duke, contrived to have Zabrzeziński deprived of two posts including the Voivodeship, even though such posts, once awarded, were rarely taken away. Herberstein reports that although they subsequently reconciled, and Zabrzeziński retained a third post, Zabrzeziński still held a grudge against Glinski.
According to 16th century Polish historian Maciej Stryjkowski and Bychowiec Chronicle, the conflict between Glinski and Zabrzeziński began after Glinski achieved the dismissal of Lida vicegerent Yuri Ilyinich and the appointment of Andrei Drozhdzh, Glinski's cousin, in his place. Yuri Ilyinich complained to the Council of Lords that his rights had been violated. The Council, including Zabrzeziński, who was a member, supported Ilyinich and declined to confirm the appointment, calling Drozhdzh a "commoner". They also drew attention to the enthronement privilege of Alexander, which said that only the deprivation of the coat of arms warranted dismissal. Alexander, angered by the disobedience, urged lords to the Brest Seimas, where he ordered them to imprison Ilyinich and demanded lords "not appear in his eyes". Despite the chronicles' description and chronology, historians note that Zabrzeziński fell out of favor due to the fact he was an active supporter of the ratification of the Union of Mielnik, which was thwarted in the Brest Seimas. Krzysztof Pietkiewicz states that in 1503 Glinski had already accused Zabrzeziński of plotting an assassination.
On August 6, 1506, Glinski triumphed over the army of the Crimean Khan near Kletsk. On August 19, Grand Duke Alexander died. In the elections Glinski supported Sigismund, Alexander's younger brother. However, under the influence of rumors spread by Zabrzeziński, Sigismund deprived Glinski and his brothers Ivan and Vasily of their posts. According to Herberstein, who called Glinski and Konstanty Ostrogski two especially famous people of the Grand Duchy,
After the king's death, the hatred which had been buried in the mind of Ivan [Jan], on account of having been deprived of his palatinate through his antagonist's influence, again awoke. The consequence was, that the latter, with his accomplices and friends, was charged with treason to King Sigismund, who had succeeded Alexander, was slandered by certain of his rivals, and declared to be a traitor to his country. The Knes Michael [Prince Mikhail], smarting under such an injury, often appealed to the king, and demanded that the cause should be equitably judged between himself and Saversinski [Zabrzeziński], declaring that he would then be able to clear himself from so heavy a charge; but finding that the king would not listen to his petition, he went over to Hungary to Vladislav, the king's brother. Thence he sent both letters and messengers to the king, imploring him to recognize his plea; but when he found that all his efforts were of no avail…

Glinski appealed for assistance to the Czech and Hungarian king Vladislav II and to the Crimean khan Mengli Giray. Vladislav II sent to the Grand Duke Sigismund ambassadors asking for Glinski's "complete satisfaction". Mengli Giray sent Sigismund a message demanding the restoration of Glinski as the Court Marshal and, in the case of non-fulfilment, threatened to break the "brotherhood" (military alliance).
In 1507 the Polish Chancellor Jan Laski warned Glinski that he would never be safe because of the threat from the Lithuanian nobility. At the same time, Vice-Chancellor Maciej Drzewicki argued that Laski intentionally incited Glinski to revolt. But, according to the American historian Stephen Christopher Rowell, Drzewicki always considered Laski as the cause of all unrest under Sigismund's reign, believing him to be a kind of "evil genius". According to Herberstein, Glinski "incensed at the indignity offered to him, he told the king that he should resent such infamous conduct, and that he himself would one day live to repent it".
Beginning
Glinski began to spread rumors that authorities intended to proselytize all Orthodox Christians to Catholicism and that those who refused to convert would be executed, even though he himself was a Catholic. As proof he relied on the statement of Fyodor Kolontaev, who allegedly had received information from the Ivan Sapieha. Later, under oath, Kolontaev denied that he said anything like this to Glinski. According to Russian historian Mikhail Krom, Prince Glinski wasn't sincere in his statements. Thus in 1509, while remaining a Catholic, Glinski reported in a letter to Emperor Maximilian that he preferred not to declare his true faith until achieving the return of his former position and therefore he asked the emperor, the Roman Church, and every Catholic for forgiveness.
Taking advantage of Sigismund's departure to the Sejm in Kraków, Glinski gathered his "brothers and friends" and told them about his intentions. From his spies he knew that his enemy Jan Zabrzeziński was in his manor near Grodno. On February 2, 1508, Glinski and a cohort of 700 riders crossed the Neman River and surrounded the manor. Then Glinski's friend German Shlyaynits broke with the people into the manor. Zabrzeziński was caught getting out of his bed and beheaded on the orders of Glinski by an unnamed Muslim. It was the beginning of the rebellion.
Having dealt with his main enemy, Glinski, who according to Polish historian Maciej Stryjkowski had 2,000 soldiers, sent units throughout Lithuania and made an attempt to take the Kaunas Castle. On February 21, Grand Duke Sigismund sent a letter to the Crimean khan with an eye to embroiling Glinski with him. Mengli Giray's greatest enemy Great Horde Khan Sheikh Ahmed was imprisoned in the Kaunas Castle and Sigismund alleged that Glinski intended to release him. After failing to take Kaunas Castle, Glinski moved his forces to Navahrudak and then to Vilnius. But, after learning that the city was already prepared for defense, he moved back to his main estate — Turov.
In Turov, Glinski negotiated with Grand Duke Sigismund, who at that time was in Kraków, and with the Council of Lords in Vilnius. Sigismund sent to Turov his man Jan Kostevich. Kostevich handed to Glinski the grand duke's promise to resolve his conflict with the Lords. But the Glinski family didn't trust the grand duke's envoy, insisting that one of the most influential Lithuanian nobles, Albertas Goštautas, was sent in his place and stating that they would wait for his arrival until March 12.
It is not entirely clear when the Glinski family began negotiations with Moscow. According to Herberstein, Wapowski, Stryjkovsky, and the Lithuanian and Samogitian Chronicle, an initiative to start negotiations with Moscow came from the Glinski family, who even before the murder of Zabrzeziński sent a messenger with a letter to the Grand Duke. Justus Ludwik Decjusz Chronicle dates this to the time after the murder. This version is supported by the fact that Glinski's negotiations with Moscow are not mentioned in Sigismund's letter to Mengli Giray dated February 21, 1508. In a letter to Vasily III, Mikhail Glinski wrote that he would take the oath to Moscow if Vasily issued a charter granting protection for his estates and property. Glinski agreed to serve with all the fortresses that he already owned and those he would be able to take by force or persuasion. Vasily III, who'd heard a lot about the abilities of the Prince, accepted the offer and sent a "made up the best way possible" agreement charter to Glinski. Russian historian Mikhail Krom, taking into account the discrepancy between sources, dates the arrival of Mikhail's envoy to Moscow to March 1508.
Russian Vremennik, a highly detailed source on the progress of the rebellion, with a protograph created in the middle of the 16th century, contains a different version of the events. The unknown author points to the fact that negotiations were initiated not by Mikhail, but by Vasily III himself. This source reports about the Moscow envoy Mitya Gouba Moklokov's arrival to the Glinski family with a charter of invitation to the service of Vasily III with their ancestral lands. The Glinski brothers didn't wait for a response from Grand Duke Sigismund and sent their man Ivan Priezhzhy to Moscow with charters asking to take them into Moscow service and to defend them and their estates.
On the Moscow service
After sending the envoy, Glinski moved to Mazyr, where his cousin Jakub Ivashintsov served as vicegerent. Probably for this reason the city was surrendered by Ivashintsov without any resistance. According to Bernard Wapowski, in Mazyr Mikhail Glinski was solemnly greeted by the Orthodox clergy.
