Cause

Following the failed first invasion at the Battle of Bun'ei in 1274, the Mongol-led Yuan dynasty of China launched a second, larger invasion of Japan in 1281, sending two substantial armies across the sea to subjugate the Japanese islands.

Event

In summer 1281, the Yuan fleets converged on Hakata Bay. By August 12 both armies were poised to attack, but on August 15 a powerful typhoon struck the Tsushima Straits for two full days, destroying the majority of the Yuan fleet and killing or drowning an estimated 80% of the invading soldiers.

Consequence

The catastrophic loss of ships and men forced the Yuan forces to abandon the invasion. The Japanese attributed their salvation to the storm, calling it kamikaze, meaning 'divine wind.' This term was later repurposed in the Second World War to describe Japanese pilots conducting aerial suicide attacks.
