which dynasty controlled the most territory

The dynasty that controlled the most territory in history is generally considered to be the Mongol Empire under the Mongol ruling house (the Borjigin clan), which at its peak in the 13th–14th centuries ruled about 9.2–9.3 million square miles of land.

Biggest dynasties by land area

• Mongol Empire (Borjigin dynasty) :
  • Peak land area around 9.2–9.3 million square miles, making it the largest contiguous land empire ever.

* Stretched from Eastern Europe to the Sea of Japan, including large parts of the Middle East, Central Asia, and the Indian subcontinent.

• British Empire (Hanover/Windsor monarchs, not called a “dynasty” in the Chinese sense) :
  • Often listed as the largest empire of any kind, with about 13.7 million square miles at its peak, but it was a maritime colonial empire rather than a single contiguous land dynasty.

• Qing dynasty (China) :
  • The largest Chinese dynasty by territory, reaching about 5.68 million square miles in the 18th century, including Tibet, Mongolia, Xinjiang, Taiwan and more.

• Russian Empire (Romanov dynasty) :
  • At its height, controlled about 8.8 million square miles of mainly contiguous territory across Eurasia, second only to the Mongols in contiguous extent.

Direct answer to “which dynasty controlled the most territory?”

If “dynasty” is taken strictly as a ruling house over a largely contiguous land empire, the Mongol Empire under the Mongol (Borjigin) dynasty is the top answer, due to its unparalleled territorial reach across Eurasia.

If the term is broadened to include overseas colonial empires under a royal line, then the British Empire under its monarchs oversaw the largest overall imperial area, though this was not usually described as a single “dynasty” in the same way as Chinese or Mongol dynasties.
