Sectarian Violence in Japan

There has been numerous instances of Christian sectarian violence in Japan since the introduction of Catholicism by Portuguese missionaries into the previously largely Nestorian Japan.

The Oda Shogunate officially criminalized adherence to the 'Portuguese Church' in 1688, resulting in a mass revolt that lead to Portugal formally establishing rule over Kyushu following a local coup. The invitation for Portuguese to administer Kyushu vindicated the fears of Japanese rulership that Catholicism would be used as a tool to undermine leadership, increasing persecution, and encouraging the Shogun to take back Kyushu.

However, Portugal saw Kyushu as too valuable and defended it intensely. It did not loose control of the island until the Franco-Spanish War in 1888, when Japanese natives were disgruntled by the increasing power of the foreign born Portuguese administrators and the increasingly dwindling power of the natives. The revolt was sparked by the offical prohibation of Japanese from entering into cleargy, effectively barricading the Japanese from entering higher education. The result was the expulsion of Portuguese sdministrators and virtually all Portuguese and Mestiço inhabitants of Kyushu. The ensuing chaos saw the Empire of Japan invade and retake Kyushu after 200 years of Portuguese occupation, with the Emperor ordering the destruction of the Iconic Portuguese built 'Our Lady of Nagasaki' cathedral. The Imperial Army dismantled the Cathedral, alledgedly forcing the inhabtants of Nagasaki to dump the bricks of the structure into the sea. Japan formally repealed its ban on Catholicism in 1890 from the First Catholic War where the Japanese Catholics once again seized Nagasaki and overpowered the Imperial Army for their right to exist
