Tongzhou mutiny

The Tongzhou mutiny (Chinese and Japanese: 通州事件; pinyin: Tōngzhōu Shìjiàn; Wade–Giles: Tungchow Shihchien; rōmaji: Tsūshū jiken), sometimes referred to as the Tongzhou Massacre, was an assault on Japanese civilians and troops by the security forces of East Hebei Autonomous Government in Tongzhou, China, on 29 July 1937, shortly after the Marco Polo Bridge Incident, which triggered the outbreak of the Second Sino-Japanese War. Approximately 260 Japanese and Korean residents were killed in the assault. This event escalated tensions between China and Japan, contributing to the further deterioration of relations following the Marco Polo Bridge Incident.
