The Seventh National Congress of the Communist Party of China (CPC) concluded on June 11, 1945 in Yan'an, Shaanxi province. The congress officially established Mao Zedong Thought as the Party's guiding ideology.

The new Constitution of the CPC adopted at the congress stated: "The CPC takes the Mao Zedong Thought that integrated Marxist-Leninist theory with the practice of the Chinese revolution as the guideline for all its work."

This helped consolidate and unite the Party in an unprecedented manner, laying the foundation for complete victory against the Japanese aggressors and later the nationwide victory of the people's democratic revolution.

The congress also stated the Party's political line, which was to "boldly mobilize the masses and expand the people's forces so that, under the leadership of our Party, they will defeat the Japanese aggressors, liberate the whole people and build a new-democratic China."

Kicking off on April 23, 1945, the 50-day congress was attended by 547 full delegates and 208 alternate delegates.
