Why was the Kellogg-Briand Pact of 1928 significant?

The Kellogg–Briand Pact (or Pact of Paris, officially General Treaty for Renunciation of War as an Instrument of National Policy) is a 1928 international agreement in which signatory states promised not to use war to resolve "disputes or conflicts of whatever nature or of whatever origin they may be, which may arise among them".

As a practical matter, the Kellogg–Briand Pact did not live up to its aim of ending war or stopping the rise of militarism. It made no immediate contribution to international peace and proved to be totally ineffective in the years following its enactment.

Sixty-two nations ultimately ratified the pact. Its effectiveness was destroyed by its failure to provide any enforcement elements. With the start of World War II, the Kellogg-Briand Pact failed to meet its goals and the clear mission it hoped to astutely meet.
