The 'Neutrality Acts' were a series of laws passed by the
United States Congress in the
1930s, in response to the growing turmoil in
Europe and
Asia that eventually led to
World War II. They were spurred by the growth in
isolationism in the US following its costly involvement in
World War I, and sought to ensure that the US would not become entangled again in foreign conflicts, especially in Europe.
America's first official position of neutrality was a Presidential Proclamation of 1793 made by George Washington. In it, he declared American neutrality in the ongoing European wars, particularly between Great Britain and Revolutionary France. It came to be called the
Proclamation of Neutrality, but for some reason, several books of popular history refer to it as "the Neutrality Act," which can cause great confusion.
The legacy of the Neutrality Acts in the 1930s was widely regarded as having been generally negative: they made no distinction between aggressor and victim, treating both equally as "belligerents"; and they limited the US government's ability to aid
Britain against
Nazi Germany, until the formal declaration of war in December 1941 rendered them irrelevant.
In each case, the acts provided for the president to invoke them by finding that a state of war existed in a particular instance. This provided a loophole that President
Franklin D. Roosevelt carefully exploited to ensure that US allies overseas were not unduly penalized by the acts.
Neutrality Act of 1936
The 'Neutrality Act of
1936', passed in February of that year, sought to close the loopholes in the 1935 Act by prohibiting trade in war materials as well as loans or credits to belligerents.
Neutrality Acts of 1937
Two Neutrality Acts were passed in 1937 (in January and May) in response to the outbreak of the
Spanish Civil War - this was not covered under the early legislation, as it applied only to conflicts ''between'' nations rather than ''within'' them. Sponsored by the isolationist
Republican Senator Arthur H. Vandenberg, it tightened the restrictions on US businesses and private individuals assisting belligerents, even prohibiting travel by U.S. citizens on ships of belligerents. When
Japan invaded
China in July
1937, starting the
Sino-Japanese War (1937-1945), President Roosevelt chose not to invoke the Neutrality Acts by declining to identify the fighting as a state of war. In so doing, he ensured that China's efforts to defend itself would not be hindered by the legislation.
Neutrality Act of 1939
The 'Neutrality Act of 1939' passed on November 4th amended the earlier legislation in recognition of the imminent Nazi threat to western Europe's democracies. Although the Act permitted all belligerents to be supplied on a "
cash and carry" basis, this benefited the
United Kingdom and
France (at war with
Germany since September 3), since they controlled the sea lanes. However, US vessels were forbidden to enter combat zones and US citizens continued to be barred from sailing on belligerent vessels. The act was amended in November
1941 to remove these restrictions following the passage of the
Lend-Lease Act.
