What social movement sought to improve the lives of immigrants and their working conditions during the early 1900s?

The Progressive Movement is the correct answer because it was centered around addressing social issues and injustices brought about by industrialization, urbanization, and immigration in the late 19th and early 20th centuries. This movement aimed to improve various aspects of American society, including the lives and working conditions of immigrants, who often faced harsh labor environments, discrimination, and lack of rights.

Progressives advocated for labor reforms, such as better wages, reasonable working hours, and safer working conditions, which significantly impacted immigrant communities. This movement also pushed for social initiatives like public health improvements, educational opportunities, and housing reforms that directly benefited immigrants who were trying to assimilate and succeed in their new country.

While the Labor Movement was also focused on workers' rights and conditions, it was often more centered on labor unions and strikes, rather than the broader array of social reforms included in the Progressive Movement. The Civil Rights Movement, which emerged later, primarily addressed racial injustices rather than specifically focusing on immigrants. The Enlightenment Movement predates the context of this question and primarily relates to philosophical advancements in the 17th and 18th centuries, rather than social reform in the early 1900s. Therefore, the Progressive Movement is seen as the driving force behind
