how did the american revolution become a world war apex
Technological and industrial history of the United States American colonies gained independence in 1783 just as profound changes in industrial production and coordination were beginning to shift production from artisans to factories. Growth of the nation's transportation infrastructure with internal improvements and a confluence of technological innovations before the Civil War facilitated an expansion in organization, coordination, and scale of industrial production. Around the turn of the 20th century, American industry had superseded its European counterparts economically and the nation began to assert its military power. Although the Great Depression challenged its technological momentum, America emerged from it and World War II as one of two global superpowers. In the second half of the 20th century, as the United States was drawn into competition with the Soviet Union for political, economic, and military primacy, the government invested heavily in scientific research and technological development which spawned advances in spaceflight, computing, and biotechnology.
