Final answer:
Many Americans were drawn to WWI due to patriotism, the quest for adventure, and the belief in war as a pathway to prove one's valor. Influential narratives and leaders instilled an idealized view of war as honorable, while disenfranchised groups saw it as a chance for social advancement.
Step-by-step explanation:
The lure of WWI for many Americans was complex and included a mix of patriotism, a search for adventure, and a desire for personal validation. For the youth of America, stories of past wars and tales of heroism played a role in shaping their perception of war as a noble endeavor, an ultimate test of manhood, and a pathway to prove loyalty and courage. Influential figures like Theodore Roosevelt also romanticized war as a test of manhood.
Many were motivated to volunteer by the idea of participating in what was perceived as a moral crusade. Women and minority groups saw the war as an opportunity for greater equality and recognition, with African Americans and Native Americans hoping that their service would be a step toward gaining rights and U.S. citizenship.
