Roman A. Bespalov, Sergey V. Polekhov.The history of the treaties between the Grand Duchy of Lithuania and the principality of Vorotynsk (1427–1491) and the Lithuanian-Vorotynsk documents of 1483 and 1488
The article includes an edition of two documents concerning the relations of Vorotynsk princes with Casimir Jagiellon (Kazimierz IV Jagiellończyk), grand duke of Lithuania (1440–1492) and king of Poland (1447–1492). The edition is accompanied with a study on the history of the Lithuanian-Vorotynsk treaties in the 15th century and the archival history of the published documents. The first of them, the treaty with the princes Dmitry Fedorovich, Ivan Fedorovich and Ivan Mikhailovich of Novosil, Odoyev and Vorotynsk issued by Casimir in 1483, originates from the archive of the Vorotynsk princes who entered the service of grand duke Ivan III of Moscow and was thereafter taken to his archive (nowadays preserved in the Russian State Archive of Ancient Acts in Moscow). Reading the document in ultraviolet rays allowed to reconstruct its text more precisely than in the mid-19th century first edition. The second document, concering prince Dmitry Fedorovich Vorotynsky’s oath to serve Casimir with the town of Kozelsk in 1488, was kept at first in the state archive of the Grand Duchy of Lithuania, in the 17th century it was taken with other documents by the Radziwiłł family, and in the 19th century acquired by the Russian official and historian Pavel Mukhanov who granted it to the Moscow Public and Rumyantsev Museum (nowadays in his collection in the manuscript department of the Russian State Library in Moscow). It was hitherto known to historians only from the short mentions in the Radziwiłłs’ archival inventories. Both documents are edited according to modern principles elaborated by the Belarusian historian Aliaksandr Hruša.
