World War I changed Americans' support for the law proposed in the document above due to factors such as exhaustion, division, patriotic fervor, and intensified propaganda.
The reasons for changed American support for the law proposed in the document can be understood in the context of World War I (WWI) and its aftermath. During the war, Americans were exhausted by the emotional and physical toll, and the societal division over international engagement such as the League of Nations.
A desire to return to 'normalcy' as articulated by President Harding emerged. The war also brought changes in societal perspectives; women's suffrage gained momentum as women's roles in war efforts highlighted the contradictions in denying them the right to vote.
Propaganda during the period focused on supporting the soldiers and even fanned ethnic and racial tensions following the attack on Pearl Harbor. However, before the US entered the war, there was significant opposition due to a variety of factors including ethnic allegiances with conflicting interests in the conflict, and the small size of the volunteer army.
WWI also created opportunities for women and African Americans as they filled roles previously reserved for white men. Yet, these societal shifts were largely expected to be temporary with a post-war return to the traditional social order.
