In World War I, the United States declared war on Germany in which month and year?

• A. January 1917
• B. April 1917
• C. July 1917
• D. December 1917

Answer: (B)

Entering World War I, the United States did not become an active belligerent until it formally declared war on Germany. The declaration by Congress, signed into law in early April 1917, made April 1917 the month and year of entry (April 6, 1917). This shift followed German submarine warfare and diplomatic pressure, including the Zimmermann telegram, that persuaded the U.S. to abandon neutrality. Therefore, the correct month and year is April 1917. The other options don’t fit because the actual congressional declaration occurred in April 1917, not January, July, or December 1917.
