“High aspiration Youth”, the first political organization of the commoners in Cochinchina, was founded by Nguyen An Ninh in late 1924 and early 1925. The organization’s name is derived from the theme of the speech: “Idéal de la jeunesse Annamite” (The ideals of An Nam youth) by Nguyen An Ninh at the headquarters of Study Promotion Association in Saigon in 1923. Established in a state of political unrest, “High aspiration Youth” not only raised public awareness of politics, organized and directed people’s movements, but also contributed to the increasing power of the Communist Party in their leadership role of the Vietnamese revolution under the Flag of Marxism-Leninism. The article clarifies Nguyen An Ninh’s role with the foundation, activities and contributions of the “High aspiration Youth” in the national liberation movement in Cochinchina from the mid-20s to the mid-30s of the twentieth century.
