Historical Context
Throughout World War I, shipping was an essential component of the American war effort.  Long before the United States formally entered the war in 1917, the U.S. sympathized with the Allies, and aided them in their struggle against the Central Powers by transporting supplies and war necessities using American ships.  When The United States officially declared war on the Central Powers, shipping was an industry of immense importance.

Ships were critical to the American military forces for many reasons.  First and foremost, in order to transport and supply soldiers in Europe, The U.S. needed a large and efficient fleet of cargo ships.  Additionally, fighting ships were also required in great numbers.  Small and nimble destroyers were produced to combat the threat of German submarines that harassed Allied shipping routes.  In addition, larger fighting ships and dreadnoughts set sail to counter enemy fleets.

Shipping was vital to supporting American involvement in the war.  However, ships were very expensive, and required time, labor, and money to produce.  Cartoons like the one seen here were created and circulated to remind Americans of the importance of shipping to the American war effort.
