The late 19th century and early 20th century, dubbed the Gilded Age by writer Mark Twain, was a time of great growth and change in every aspect of the United States, and even more so for big business. It was this age that gave birth to many of the important modern business practices we take for granted today, and those in charge of business at the time were considered revolutionaries, whether it was for the good of the people or the good of themselves.

The members of the Grange banded together and put up a big fight against the railroads, a fight which eventually led to the basis of the Interstate Commerce Act of 1887. This
