Vasili I Dmitriyevich
- Born: 1371
- Marriage: Sophia of Lithuania
- Died: Feb 1425 at age 54
Vasiliy I Dmitriyevich, Grand Prince of Moscow since 1389, oldest son of Dmitri Donskoi and Grand Princess Eudoxia - daughter of the Grand Prince Dmitry Konstantinovich of Nizhny Novgorod.
Vasili I continued the process of unification of the Russian lands: in 1392, he annexed the principalities of Nizhny Novgorod and Murom; in 1397-1398 - Kaluga, Vologda, Veliki Ustyug and Komi people's lands.
During the reign of Vasiliy I, feudal landownership kept growing. With the growth of princely authority in Moscow, feudals' judicial powers were partially diminished and transferred to Vasili's deputies and heads of volosts.
To prevent Russia from being attacked by the Golden Horde, Vasiliy I entered into alliance with Lithuania in 1392 and married Sophia of Lithuania, the only daughter of Vytautas the Great. The alliance turned out to be fragile, since Vytautas would later capture Vyazma and Smolensk in 1403\endash 1404.
In Vasiliy's reign occurred the invasion of Timur (1395), who ruined the Volgan regions but did not penetrate so far as Moscow. Indeed Timur's raid was of service to the Russian prince as it damaged the Golden Horde, which for the next twelve years was in a state of anarchy. During the whole of this time no tribute was paid to the khan, Olug Moxammat, though vast sums of money were collected in the Moscow treasury for military purposes. In 1408 Edigu ravaged Muscovite territory, but was unable to take Moscow. In 1412, however, Vasiliy found it necessary to pay the long-deferred visit of submission to the Horde.
The growing influence of Muscovy abroad was underlined by the fact that Vasiliy married his daughter Anna to Emperor Ioannes VIII of Byzantium.
Vasili married Sophia of Lithuania, daughter of Vytautas 'the Great' and Unknown.
