Murakami sea lords
Noshima, Geiyo Islands, Seto Inland Sea, Japan
What happened
From the 1300s, the Murakami clan controlled the narrow sea routes through the islands of Japan's Seto Inland Sea. Ships paid them tolls for safe passage, and they also escorted travellers and fought as navies for powerful lords. Japanese sources often call them 'kaizoku', meaning pirates, but they acted more like sea lords who kept order on the water.
Why it matters
For about 200 years, the Murakami controlled one of Japan's busiest sea routes. Their fleets helped decide important battles in a time of war between Japanese lords.
What came next
In the late 1500s, the ruler Toyotomi Hideyoshi banned piracy, and the Murakami lost their independence. Their island fortress at Noshima was abandoned in 1588, and the Murakami Kaizoku Museum on Ōshima, in Imabari, tells their story today.
Did you know?
The whole tiny island of Noshima was turned into a fortress, with its hills cut into flat terraces.
