Vietnam, 1900–1945: Colonial Rule and the Struggle for Independence

At the beginning of the twentieth century, Vietnam was under French colonial rule. Its territory was divided into three administrative regions: Tonkin in the north, Annam in the center, and Cochinchina in the south. Together with Cambodia and Laos, these formed French Indochina. Although Vietnam’s emperor remained in place, French officials held the decisive power. For ordinary Vietnamese, the central question was how to preserve their identity and regain control of their country.


French rule changed Vietnam’s economy and society. Railroads, roads, ports, and schools expanded, but development largely served colonial administration and commerce. Rice exports, rubber plantations, and coal mining generated wealth that was unevenly distributed. Many peasants faced heavy taxes, debt, and insecure access to land, while plantation and industrial workers endured difficult conditions. Access to French education remained limited, yet it helped introduce political ideas that Vietnamese thinkers would use to challenge colonial authority.



Resistance took several forms. Phan Boi Chau sought independence through revolutionary organization and foreign assistance. In 1905, he traveled to Japan, whose modernization inspired many Asian nationalists. His Dong Du, or “Go East,” movement encouraged Vietnamese students to study there and prepare for national liberation. French pressure helped bring the movement to an end in 1909. Another reformer, Phan Chau Trinh, emphasized education, modernization, and changes to Vietnam’s political traditions. Their approaches differed, but both helped awaken a new generation’s national consciousness.


During the following decades, nationalism spread through newspapers, schools, political organizations, and overseas communities. Nguyen Ai Quoc, later known as Ho Chi Minh, became an influential revolutionary after years abroad. He connected the struggle for independence with communism and helped establish a communist party in 1930. Other nationalists pursued different paths, including the Vietnamese Nationalist Party, whose unsuccessful Yen Bai uprising that year brought severe French repression. Vietnamese resistance was therefore diverse, united more by opposition to colonial rule than by agreement about Vietnam’s future.


World War II transformed this struggle. In 1940, Japanese forces entered northern Indochina, later extending their presence southward. French colonial officials continued administering the territory under Japanese domination. Vietnamese people consequently lived under overlapping foreign authorities. In 1941, Ho Chi Minh returned to Vietnam and helped establish the Viet Minh, a communist-led independence movement that sought broader nationalist support. It organized resistance, developed rural networks, and fought the Japanese occupation.


In March 1945, Japan overthrew the French administration. Meanwhile, famine devastated northern Vietnam, driven by disrupted food supplies, wartime policies, and poor harvests. Hundreds of thousands died, with many estimates reaching one to two million. Japan’s surrender in August created an opening, and the Viet Minh seized power during the August Revolution. On September 2, Ho Chi Minh proclaimed the Democratic Republic of Vietnam in Hanoi. Independence, however, remained contested. France sought to restore its authority, while competing Vietnamese groups pursued their own visions. World War II ended with Vietnam poised between the promise of self-government and renewed conflict over who would govern the nation.
