Source-derived summary

Year 1238 (MCCXXXVIII) was a common year starting on Friday of the Julian calendar.

Events

By place

Mongol Empire

January 15–20 – Siege of Moscow: The Mongols under Batu Khan and Subutai campaign across the northern heartland of the Kievan Rus', committing numerous atrocities across multiple settlements, including the sacking of an insignificant town known as Moscow. According to the Chronicle of Novgorod, Moscow is a fortified village, a trading post "on a crossroads of four rivers". The village is taken by the Mongols after 5 days of siege.

March 4 – Battle of the Sit River: The Mongols defeat a Kievan Rus' army (some 4,000 men) under Grand Prince Yuri II of Vladimir in an engagement at the Sit River (located in the Sonkovsky District). With Yuri's death, so too dies the hope of any united Rus' resistance against the Mongols. Batu Khan splits his forces up into several contingents – ordering each to wreak havoc across the Rus' territories (modern-day Russia and Ukraine).

March – Siege of Kozelsk: The 12-year-old Prince Vasily of Chernigov (grandson of Mstislav II Svyatoslavich), manages against all the odds, to hold out in his capital of Kozelsk for nearly two months with only citizen militia. He leads a successful sortie outside of the walls – where the garrison slaughters thousands of Mongols and destroys siege equipment. Finally, Kozelsk is conquered and Vasily is slaughtered alongside the inhabitants.

Editorial analysis

Why this record matters

The phrase “year” 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.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 7, 2026. The linked authority identifier is Q5433. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1238.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
