During the period between 1865 to 1898, the turn of the century was approaching the nation. The end of the Civil War marked this transition from a more agricultural nation to an industrialized one. Society in America was becoming significantly more urbanized and more diversity was introduced to larger cities on the east coast. This transformation of the United States from an agricultural to an increasingly industrialized and urbanized society brought about significant economic, political, diplomatic, social, environmental, and cultural changes. .
Amid the close of the 1800s, American society was being molded into an industrial powerhouse. A significant part of this transformation came from manufacturing and factories growing at an incredibly rapid pace. Along with the increase in manufacturing came the movement of thousands into large cities. The new found industrialization provided a growing need for more workers, leading to the population spike in the large cities such as New York and Chicago. This direct relationship between the industrial development and population growth shows how the post-Civil War transformation had such consistent and rapid proliferation. .
In the dawn of industrial development in America we also see the first men to get extremely wealthy from these new opportunities. Billionaire John D. Rockefeller was one of the more prominent examples of such accomplishments. Rockefeller acquired his significant wealth from his very own Standard Oil Company. Through the Standard Oil Company, Rockefeller gained a hefty portion of the oil industry. He was known for his ability to control and gain an edge on competition, a key part of his success with Standard Oil. Known as the Baron of U.S. steel, Andrew Carnegie dominated the advancement in lowering production costs and improving manufacturing methods of quality steel for America. His success through this enterprise can be accredited to his ardent work ethic.
