In 1891, Cachin joined Jules Guesde's French Workers' Party (POF). In 1905, he joined the new French Section of the Workers' International (SFIO) and won election to the Chamber of Deputies representing the Seine in 1914. He rallied the Union sacrée during the First World War and was sent to Russia in a mission in 1917. On that occasion he strongly supported Kerensky's Provisional Government, which was pledged to continue Russia's participation in World War I, and denounced Lenin and the Bolsheviks. In 1918, he was one of the speakers at a patriotic rally held at Strasbourg, to celebrate the city's return to French rule.
However, following the end of the war, there was a leftward shift among Cachin's grassroots supporters and a growing sympathy for the October revolution. In 1920 at the Tours Congress, Cachin became one of the founders of the French Communist Party (SFIC) and joined the Third International. In 1923, he was jailed for denouncing the French occupation of the Ruhr and Morocco. As a strong supporter of the pro-Soviet Communist Party, he refused to disavow the Molotov–Ribbentrop Pact and was removed from elected office in 1940. After the Liberation of France, he returned to the National Assembly until his death in 1958.
At the age of 88, he was the first foreigner to receive the Order of Lenin. In the later part of his life, he was nicknamed "Grandfather of the Communist Party".
His granddaughter, Françoise Cachin, was an art historian.
