The Mongol Empire was the largest contiguous land empire ever
In a single lifetime it grew from feuding nomad clans into an unbroken realm stretching from the Pacific almost to Europe.
The British Empire was bigger overall, but it was scattered across oceans. The Mongol Empire holds a different record: the largest contiguous land empire in history — one unbroken stretch of territory you could, in principle, ride across.
It grew with startling speed. After a council proclaimed Temujin as Genghis Khan, ruler of all Mongols, in 1206, the empire expanded until it covered some 9 million square miles (23 million km2) of Eurasia, reaching from the Sea of Japan toward Eastern Europe.
By the time Genghis Khan died in 1227, the empire was already roughly twice the size of the Roman Empire at its height.
Much of the conquest was the work of mounted archers and a brutal, highly mobile cavalry, but holding it together relied on organisation — a relay messenger network, the yam, let orders and intelligence travel across the continent far faster than any rival state could manage.
