Siege of Moscow: The Golden Horde led by Tokhtamysh lays siege to the capital of the Principality of Moscow.

The siege of Moscow in 1382 was a battle between the Principality of Moscow and Tokhtamysh, khan of the Golden Horde.

The Golden Horde, self-designated as Ulug Ulus, was originally a Mongol and later Turkicized khanate established in the 13th century and originating as the northwestern sector of the Mongol Empire. With the division of the Mongol Empire after 1259, it became a functionally separate khanate. It is also known as the Kipchak Khanate or the Ulus of Jochi, and replaced the earlier, less organized Cuman–Kipchak confederation.

Tokhtamysh was Khan of the Golden Horde from 1380 to 1395. He briefly succeeded in consolidating the Blue and White Hordes into a single polity.

The Grand Principality of Moscow, or Muscovy, known as the Principality of Moscow until 1389, was a late medieval Russian monarchy. Its capital was the city of Moscow. Originally established as a minor principality in the 13th century, the grand principality was transformed into a centralized Russian state in the late 15th century.
