The new freedoms women enjoyed in the 1920s were largely contributed to by the end of World War I and the popularization of contraception.
The end of World War I played a significant role in reshaping societal roles, as women took on jobs and responsibilities that were traditionally held by men, leading to increased demands for gender equality and rights. Additionally, the popularization of contraception gave women more control over their reproductive health and choices, which contributed to their newfound freedoms and independence during this era.
While the Equal Rights Amendment was introduced in the 1920s, it was not ratified until later, so it did not directly contribute to the freedoms women experienced during that specific decade. The Revenue Act of 1924 focused on taxation issues and did not directly impact women's rights or freedoms.
