The purpose of the Kellogg-Briand Pact was to basically outlaw war. The pact was signed, in August of 1928, by France, Germany and the United States. The pact is named after its two authors, Frank B. Kellogg and Aristide Briand.
Other countries began to sign the agreement a short time later, but the pact was soon shown to be flawed by Japan in 1931. The Asian country invaded China and with economic issues, along with the lack of desire to go to war there was no attempt to enforce the sanctions set up in the pact. The pact was later tested by the Axis powers in World War II, showing that it was not going to be possible to enforce the pact.
