A viral theory claiming the Tang dynasty, imperial China's celebrated golden age of arts and poetry spanning 618 to 907, was entirely fabricated by historians took hold on Weibo and Bilibili starting in late April. The claim originated with a vlogger who cited his own study of astronomy and calendars, offered no motive, and has since been banned.
State media, cyber censors, and university academics mobilized through the summer to purge the theory and publish rebuttals, with the Communist Party's People's Daily asking in August why 'absurd arguments' capture young people. The conspiracy drew energy from Han nationalist resentment of the Tang rulers' mixed ancestry, an inconvenient detail given China's long history of non-Han dynasties.
The Party has warned for decades against 'historical nihilism,' any interpretation of the past that questions its Marxist-Leninist legacy, and Xi Jinping flagged the risk soon after taking power in 2012. The scrubbing was thorough enough that, online, only the debunkings now remain.
