Vasily I of Moscow
Grand Prince of Moscow (1372-1425)

Vasily I Dmitriyevich (Russian: Василий I Дмитриевич; 30 December 1371 – 27 February 1425) was Grand Prince of Vladimir and Moscow from 1389. He was the heir of Dmitry Donskoy, who reigned from 1359 to 1389.
He entered an alliance with the Grand Duchy of Lithuania in 1392 and married Sophia, the only daughter of Vytautas, though the alliance turned out to be fragile, and they waged war against each other in 1406–1408.
The raid on the Volga region in 1395 by the Turco-Mongol emir Timur resulted in a state of anarchy for the Golden Horde and the independence of Moscow. In 1412, Vasily resumed submission to the Horde.
Family and early life
Vasily was the oldest son of Dmitry Donskoy and Grand Princess Eudoxia, daughter of Grand Prince Dmitry Konstantinovich of Nizhny Novgorod.
Reign
While still a young man, Vasily, who was the eldest son of Grand Prince Dmitry Donskoy (ruled Moscow 1359–1389), travelled to the Tatar khan Tokhtamysh (1383) to obtain the Khan's yarlik (patent) for his father for the title of grand prince of Vladimir. Diplomatically overcoming the challenge of the prince of Tver, who also sought the patent, Vasily succeeded in his mission. But he was subsequently kept at Tokhtamysh's court as a hostage until 1386 when, taking advantage of Tokhtamysh's conflict with his suzerain Timur Lenk (Tamerlane), he escaped and returned to Moscow.
With Tokhtamysh's permission, Vasily I took over Nizhny Novgorod-Suzdal in 1393.

Why this record matters
The phrase “grand Prince of Moscow (1372-1425)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
