Was the league of nations a success in the 1920s??
Definately not, the League failed to stop the Nazi uprising and failed to stop Hitler from taking Poland. The League was an utter disgrace.
The League was a good idea in theory, but lacked any legitimacy or credibility.
Since the league of nations no longer exists, I would say it was not a success.
it wasnt a success as it later got renamed as the united nations
