In the early twentieth century, the United States was a powerhouse in industrial production, leading the world in outputs like petroleum and copper, which fueled not just its own economy but global development as well. This ambitious industrial growth marked a significant shift as the U.S. transitioned from a primarily agrarian society to an industrial leader on the world stage. Additionally, the U.S.'s engagement in international affairs shifted the paradigm as it began to influence other nations through initiatives like Progressivism, promoting social reforms and modernization. This active involvement illustrated a unique blend of domestic development impacting global standards, contrasting with the colonial approaches taken by European powers.
