Final answer:
In 1935, Italy invaded Ethiopia, which led to condemnation by the League of Nations, who imposed economic sanctions. However, these sanctions were undermined by the lack of military enforcement and the incomplete support of member nations, demonstrating the League's inability to manage international conflicts effectively.
Step-by-step explanation:
In 1935, Italy invaded Ethiopia, an action that was condemned by the League of Nations. The League attempted to enforce economic sanctions against Italy as a response to their aggression. However, the absence of a military arm and full international cooperation undermined these sanctions, rendering them ineffective. This ultimately led to Ethiopia being conquered by Italy, and showcased the weakness of the League in preventing or curbing aggressions between nations prior to World War II.
The League's condemnation of the invasion and implementation of sanctions highlighted its lack of enforcement power. Countries like the United Kingdom and France did not fully support the sanctions due to their own national interests, resulting in a limited impact on Italy. The League's failure to stop Italian aggression demonstrated to the world that the organization could be challenged with few consequences, a significant factor in the lead-up to World War II as aggressive acts by countries such as Italy and Japan went unchecked.
