The Nye Committee, officially known as the Special Committee on Investigation of the Munitions Industry, was a United States Senate committee, chaired by U.S. Senator Gerald Nye (R-ND). The committee investigated the financial and banking interests that underlay the United States' involvement in World War I and the operations and profits of the industrial and commercial firms supplying munitions to the Allies and to the United States. It was a significant factor in public and political support for American neutrality during the Great Depression. The resulting Neutrality Acts are now generally regarded as having aided the rise of Nazi Germany and the laws were repealed in 1941.
