Step-by-step explanation:
The main aims of the League of Nations when it was set up in 1920 were to promote global security, prevent future wars, and facilitate good relations among member countries.
One of the primary goals of the League was to achieve collective security, which meant that member states would jointly retaliate against any aggressive action by another state. The idea was to deter aggression and maintain peace.
Additionally, the League aimed to resolve international disputes peacefully through negotiations and mediation, and to punish aggression by imposing economic sanctions or military actions if necessary.
The main aims of the League of Nations when it was set up in 1920 were to promote global security and to prevent future wars through the collective actions of its member nations.
