The Inner Mongolia incident, or the Inner Mongolia People's Revolutionary Party purge incident, (Chinese: 内人党事件; pinyin: Nèi rén dǎng shìjiàn) was a massive political purge which occurred during the Cultural Revolution in Inner Mongolia. The purge was supported by the Central Committee of the Chinese Communist Party and was led by Teng Haiqing, a lieutenant general (zhong jiang) of the People's Liberation Army. It took place from 1967 to 1969 during which over a million people were categorized as members of the already-dissolved Inner Mongolian People's Revolutionary Party (PRP), while lynching and direct massacre resulted in the deaths of tens of thousands, most of whom were Mongols.
