Interwar Imperialism, Mandates and Anti‑Colonial Resistance

The victorious powers kept or even expanded their imperial holdings after the war, despite the substantial contributions of colonial subjects to the Allied effort. The Republic of Turkey, led by Mustafa Kamal (Ataturk), stood out as a rare exception that achieved independence. U.S. President Woodrow Wilson repeatedly urged that “self‑determination ought to be the guiding principle of a post‑war world,” a promise that colonial peoples interpreted as a pathway to freedom. British and French leaders rejected Wilson’s idealism, opting instead for a compromise that became the mandate system.

The Mandate System

The League of Nations administered the redistribution of former Ottoman and German territories through a three‑tiered classification.

• Class A territories—large populations considered ready for self‑rule—were placed under British or French control in places such as Iraq, Israel, Syria, and Lebanon.
• Class B territories—larger but underdeveloped populations—were governed by the victors, exemplified by the former German colonies in Africa.
• Class C territories—small, sparsely populated areas—were treated essentially as colonies, including many Pacific islands.

The system’s stated goal of preparing peoples for eventual independence conflicted with the reality of continued imperial administration, a discrepancy highlighted by the quote: “When they got out from one imperial thumb only to find a different Imperial thumb descending upon them that not surprisingly led to Fierce anti Colonial resistance.”

Japanese Imperialism

Japan emerged as the only non‑Western state to attain major‑power status in the interwar era. In 1931 it invaded Manchuria, violating League of Nations rules, and faced international criticism. In response, Japan withdrew from the League and, in 1932, established the puppet state of Manchukuo. The Japanese government then promoted regional dominance through the “Greater East Asia Co‑Prosperity Sphere.” As one speaker noted, “Japan was kind of an outlier in the world Imperial party since it was the only non‑western state to make themselves equal to Western power.”

Anti‑Colonial Resistance Movements

The Indian National Congress, founded in the late 19th century, shifted in the 1920s toward peaceful protest under Mahatma Gandhi’s leadership. Gandhi’s rise in the 1920s marked a turning point for Indian demands for self‑rule. In South Africa, the African National Congress was created by Western‑educated professionals who advocated for equal rights and drew inspiration from pan‑African ideas. Both movements continued to confront imperial control well into the post‑World‑II period, illustrating the broader pattern of fierce anti‑colonial resistance across the globe.
