Mao Zedong attended as a Hunan delegate. The meeting founded the Chinese Communist Party as a section of the Comintern world. It did not found a state, an army, or a literacy system.

What the sources establish

Britannica’s CCP article dates the First Congress to July 1921 and names the Shanghai–Jiaxing sequence. Mao’s later Selected Works reprint early essays; they are not the congress minutes. No Factrail original membership census is supplied.

Established: Mao attended the 1921 founding congress as a Hunan delegate. Not established: that he drafted the party programme, that 1921 already implied 1958, or that attendance equals chairmanship.

Shared responsibility is part of Mao attends the First National Congress of the Chinese Communist Party in Shanghai. Naming Mao Zedong does not delete co-authors, institutions, or later transmitters. The lag from 1921-07-23 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

If a number is not in the two records named above, it is not supplied here.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
