In 1929, the Kellogg-Briand Pact, renouncing war as an instrument of foreign policy, went into effect. The pact was named after the American secretary of state Frank B. Kellogg and French foreign minister Aristide Briand, who drafted the framework agreement. It was first signed in Paris on August 27, 1928 by most leading world powers, ushering in a new era of peace of prosperity.
