The National Representatives' Congress was a significant political gathering held in Sơn Dương, involving representatives from different political factions striving for Vietnamese independence. This assembly occurred in the wake of World War II's tumultuous impact on Southeast Asia and the weakening of French colonial power in Vietnam. Delegates from various backgrounds came together in a shared goal of establishing a governance system that would represent the interests of the Vietnamese people. Key figures, including leaders from the Viet Minh and other nationalist groups, emphasized the importance of collaboration in achieving a unified front against colonial rule. The congress is notable for its democratic tone and aspirations towards the establishment of a national assembly that could effectively govern and reflect the desires of the populace.

Despite the pressures of external conflicts and internal divisions, the congress managed to propose a platform that highlighted national sovereignty, social equity, and disregard for previous colonial frameworks. The decisions made during the congress laid the groundwork for future political developments in Vietnam and bolstered the resolve of those seeking independence. It served as an incubator for ideas that would later take shape in the formal establishment of the National Assembly, representing a pivotal moment in Vietnam's journey towards self-rule.
