The Manchurian Crisis was a significant event in the interwar period that highlighted the limitations of the League of Nations. When Japan invaded Manchuria in 1931, it did so without League approval or adequate justification, leading to a situation where the League's ability to maintain peace and security was fundamentally challenged. The League's response was largely ineffectual; while it convened discussions and set up a commission to investigate the invasion, it failed to take decisive action against Japan or enforce any meaningful sanctions.

As a result, the actions of Japan during the crisis demonstrated the League's inability to confront aggression from a major power, which significantly undermined its credibility and authority. Many nations observed that the League could not protect smaller states from the predatory actions of larger ones, leading to the perception that the League was weak and ineffective in maintaining international order. This crisis contributed to the growing disillusionment with the League of Nations and foreshadowed the conflicts that would lead to World War II.
