Andrey Bolshoy was born in
Uglich. After the death of his father in 1462, Andrey Bolshoy inherited the cities of Uglich,
Zvenigorod, and
Bezhetsk. His relations with his older brother,
Ivan III of Moscow, were cordial at first. It was ten years later that the death of their brother, the childless
Yury of Dmitrov, led to bad blood between the two. Ivan III appropriated Yury's
appanage for himself, rather than sharing it with his brothers. At last he granted some of Yury's lands to his other brothers, except Andrei Bolshoy, who had been coveting them more than others. Another conflict between the two brothers was triggered by the right of
boyars to leave their own prince for the courts of other princes. Ivan III would only allow such practice if a boyar were to move to Moscow. In 1479, one displeased boyar, Prince Lyko-
Obolensky, left the
Moscow Kremlin and settled at the court of his brother Boris, ruler of
Volokolamsk. When the latter refused to extradite the boyar, Ivan III ordered to capture Lyko-Obolensky and deliver him to Moscow in chains. Andrei Bolshoy took the side of the offended prince of Volokolamsk. The two brothers joined their armies and marched towards
Novgorod and then to the
Lithuanian border. There, they began to negotiate with the
Polish king
Kazimierz IV, who decided not to interfere in the conflict. Boris and Andrey then sought support in
Pskov, but to no avail. In order to settle the conflict, Ivan III offered Andrei Bolshoy the cities of
Kaluga and
Aleksin, but he refused. The invasion of
Khan Akhmat in 1480 reconciled the grand prince with his brothers. Ivan III became more tractable and promised to fulfill all their demands. Andrei and Boris moved their armies to the
Ugra River and joined Ivan III in his
stand-off with the Mongols. Their reconciliation was mediated by their mother,
metropolitan and a number of
bishops. As a token of their reconciliation, the grand prince granted Andrei the city of
Mozhaisk, the most coveted part of Yury's appanage. After the death of their mother
Maria of Borovsk in 1484, Andrei's situation became perilous because his defiant stance and groundless claims filled Ivan III with misgivings. He was afraid that, in line with the ancient system of Rurikid succession, Andrey would attempt to usurp the throne of Muscovy after his own death. In 1488, Andrey was informed about Ivan's plans to dethrone and imprison him. Upon his epistolary complaint to the grand prince, the latter protested his innocence. In 1491, Ivan III ordered Andrei and Boris to send their armies to help out his ally
Meñli I Giray. For reasons unknown, Andrei disobeyed the grand prince. When he came to Moscow in 1492, he was arrested and put in prison in
Moscow, where he died in 1493. Thereupon Andrey's sons – Ivan and Dmitry – were imprisoned in
Vologda, while their appanage – Uglich – was annexed into Muscovy. ==References==
