The principalities at the turn of the 15th century
In Russian historiography, the Upper Oka Principalities, also known as the Upper Principalities or the Principalities of the Upper Reaches, were a number of small Russian principalities situated along the upper reaches of the Oka River around the turn of the 14th and 15th centuries.
History
Estate of a petty medieval prince
They were formed between the 13th and 15th centuries as a result of the fragmentation of the Principality of Chernigov. They were ruled by the "upper princes", each descended from Mikhail Vsevolodovich. His eldest son, Roman, received Bryansk, and his line was considered senior. The Bryansk princes were crushed by the Golden Horde due to their aspirations for unification, leading to the emergence of independent appanage principalities in the mid-14th century.
The princes of Novosil and Tarusa participated in the all-Russian congress[ru] of princes in Pereslavl-Zalessky in 1374. The following year, the princes of Novosil, Tarusa, and Obolensk were mentioned as participating in the all-Russian campaign against Tver. Many of the "upper princes" also took part in the Battle of Kulikovo in 1380. However, around the turn of the 15th century, Lithuania renewed its campaign to increase its control over the region.
In the early 15th century, the princes became dependent on Lithuania and were required to pay an annual tribute. In 1395–1396 or 1406–1408, the Lithuanians were able to capture Obolensk, Tarusa, Mtsensk, Mosalsk, Vorotynsk, Mezetsk, Karachev, and Kozelsk. In 1408, the princes of Belyov and Peremyshl fled to Moscow, along with Švitrigaila and other princes. At the same time, the princes quarrelled with each other over the boundaries of their holdings. Increased Lithuanian oppression in the territories bordering Muscovite lands led to discontent among Russian princes and nobles. The principalities of Karachev, Kozelsk, and Tarusa were abolished; the descendants of those princes were reduced to the status of minor service princes.
In the second half of the 15th century, as religious oppression intensified, Grand Prince IvanIII took advantage of the situation and began to interfere in the relations of the princes who were in Lithuanian service. As a result, these princes began to "depart" to Moscow. A border conflict between Lithuania and Russia took place in 1487–1494, consisting of minor clashes and generally waged by the forces of the border principalities. According to a 1494 treaty, Lithuania was compelled to recognize these principalities as belonging to the Russian state. The incorporation of these principalities strengthened Moscow's southwestern border, and some of them continued to exist as appanages until 1573, including Vorotynsk, Novosil, and Odoyev.
