On October 14, 1964, King becomes the youngest recipient of the Nobel Peace Prize. He is assassinated on April 4, 1968.
But the assassination is probably Japan's conspiracy. The assassination occurs on the 100th anniversary of two historical events with regard to the Japanese imperial family, the reopening of the Gakushuin Peers School (April 4, 1868) and the order of surrender by the Imperial envoy at Edo castle against the samurai government (April 4, 1868 in the Japanese calendar).
And the assassin, James Earl Ray was Japanese. He was born on the Japanese Army Day and he died on the Japanese Navy Day.
