The siege of Moscow in January 1238 was part of the Mongol invasion of Kievan Rus'.
== Prelude == Following the destruction of Ryazan on 21 December 1237, Grand Prince Yuri II dispatched his sons Vsevolod and Vladimir with most of the Vladimir-Suzdal army to confront the Mongol forces at the Battle of Kolomna. The Suzdalian army suffered a decisive defeat, and the remaining troops retreated north toward Vladimir and Moscow.
== Siege == After the destruction of Kolomna in January 1238, Prince Vladimir, the younger son of Yuri II of Vladimir, retreated to Moscow with a small contingent of survivors. According to the Chronicle of Novgorod, “And the men of Moscow ran away having seen nothing”. At the time, Moscow was a small fortified settlement and trading post located “on a crossroads of four rivers”. The wooden fortification was captured after a five-day siege.
== Aftermath == Prince Vladimir was captured by the Mongol forces and executed two weeks later in front of the defenders of Vladimir, serving as a warning to the besieged.
