What happened
Kublai Khan sent a fleet of some 800 to 900 ships and 16,600 to 40,000 Mongol, Chinese, and Korean troops against Japan in November 1274, but after initial victories the invaders withdrew to their ships rather than push inland, possibly due to supply problems, and the fleet later withdrew entirely. After Japanese forces beheaded a follow-up embassy demanding tribute, Kublai launched a far larger invasion in June 1281: 4,400 ships and roughly 100,000 troops, reinforced later by another 40,000. Japanese fortifications built in the interim held at Hakata, and the combined Mongol fleets moved toward Takashima. On 14 August a typhoon destroyed most of the Mongol fleet, wrecking ships that had been chained together for defense against Japanese raiding boats; the World History Encyclopedia estimates half to two-thirds of the Mongol force was killed. The storm winds became known in Japan as kamikaze, or 'divine winds,' credited to the war god Hachiman answering Japanese prayers.
Why it matters
The 1281 disaster ended any realistic Mongol hope of conquering Japan and gave rise to the kamikaze legend that would echo through Japanese culture for the next 660 years. It also marked one of the clearest limits of Mongol military dominance: naval warfare and unfamiliar weather defeated an army that had beaten every major land power it faced from Korea to Hungary.
How we know
The invasion fleet sizes, the fortifications at Hakata, and the typhoon's timing and destructive scale are detailed in the World History Encyclopedia's biography of Kublai Khan.
