Great Genna Martyrdom
1622 execution of 55 Christians in Nagasaki / From Wikipedia, the free encyclopedia
The Great Genna Martyrdom, also known as the Great Martyrdom of Nagasaki, was the execution of 55 foreign and domestic Catholics killed together at Nishizaka Hill in Nagasaki, Japan, on 10 September 1622. Beginning in 1614, Christianity was banned in Japan and a smuggling incident concerning two foreign missionaries prompted the killing. The mass execution was part of the persecution of Christians in Japan by Tokugawa Hidetada, the second Shogun of the Tokugawa shogunate.
