President Woodrow Wilson Signs the National Defense Act: Strengthening America’s Defenses on June 3

June 3 is a strong and important day in U.S. presidential history — it's the date in 1916 when President Woodrow Wilson signed the National Defense Act into law!

This big law made the National Guard much larger and stronger. It increased the size of the National Guard (the part-time citizen soldiers from each state) and made it a permanent reserve force ready to help the regular Army when needed. The Act also created new training programs, allowed for more officers, and prepared America in case it had to join World War I (which happened the very next year).

At the time, many people in the U.S. wanted to stay out of the war in Europe, but President Wilson knew the country needed to be ready and safe. The National Defense Act helped make sure America had enough trained soldiers if trouble came.

If you're learning about the military, how America prepares for safety, or presidents getting the country ready during tough times, this June 3 event is a great one to know!
