# The Lushan plenum denounces Peng Dehuai and criminalizes Leap criticism

Date: 1959

## The fact

At the Lushan work conference and the Eighth Plenum in July–August 1959, [Mao Zedong](/people/mao-zedong) denounced Defence Minister Peng Dehuai after Peng’s 14 July letter described Leap disasters. The plenum adopted a resolution on the ‘anti-party clique’ of Peng, Huang Kecheng, Zhang Wentian, and Zhou Xiaozhou. Intra-party criticism of the Leap became a crime. Famine continued. Later museums, competitions, UNESCO lists, and translations are not this Fact. The CCP, State Council, PLA, and local cadres may share the file; they do not erase a documented decision, and they are not a licence to treat every local killing as his handwriting.

## Context

Peng was a marshal, not an outsider. His letter was initially an internal opinion. Mao recoded it as a line struggle linked to Khrushchev. Lin Biao replaced Peng at defence. The 7000 Cadres Conference of 1962 later admitted errors without restoring Peng. That conference is not this Fact. Later museums, competitions, UNESCO lists, and translations are not this Fact. The CCP, State Council, PLA, and local cadres may share the file; they do not erase a documented decision, and they are not a licence to treat every local killing as his handwriting.

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

## Evidence and sources

Wilson Center publishes Peng’s letter and related documents. Britannica independently narrates the Lushan purge. Plenum resolution language is in party collections. No private diary is required to establish the purge. Later museums, competitions, UNESCO lists, and translations are not this Fact. The CCP, State Council, PLA, and local cadres may share the file; they do not erase a documented decision, and they are not a licence to treat every local killing as his handwriting.

## Significance

Worsening justice path: the last high-level correction attempt was punished. Direct contribution. High confidence. This is why the famine was not stopped in 1959. Later museums, competitions, UNESCO lists, and translations are not this Fact. The CCP, State Council, PLA, and local cadres may share the file; they do not erase a documented decision, and they are not a licence to treat every local killing as his handwriting.

Confidence is stated on the impact path, not hidden in adjectives. Do not treat Lushan as the famine itself. Do not treat Peng as a liberal democrat. Mixed effects of The Lushan plenum denounces Peng Dehuai and criminalizes Leap criticism are separate paths.

## What is established and what is not

Established: Mao drove Peng’s 1959 purge after the letter. Not established: that Peng offered a full alternative economic programme, or that restoration in 1962 would have been automatic without the purge. Later museums, competitions, UNESCO lists, and translations are not this Fact. The CCP, State Council, PLA, and local cadres may share the file; they do not erase a documented decision, and they are not a licence to treat every local killing as his handwriting.

Shared responsibility is part of The Lushan plenum denounces Peng Dehuai and criminalizes Leap criticism. Naming Mao Zedong does not delete co-authors, institutions, or later transmitters. The lag from 1959-08-02 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.

The contribution type is direct. The attached driver is justice-[judicial-independence](/drivers/justice-judicial-independence-erosion)-erosion. The welfare reading used in this dossier is worsening. That reading is an impact-path choice, not a property stored on the Fact itself.

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