Since Rockefeller had created the largest business empire of the late nineteenth century, it was only fitting that he should face the most massive antitrust suit of his day. Some 444 witnesses delivered 11 million words of testimony; swollen by 1,374 exhibits, the proceedings filled 12,000 pages in 21 thick volumes. Before it was over, Standard Oil also contested some 21 state antitrust suits from Texas to Connecticut, leading one historian to comment, “Never before in the history of the United States had there been so far-reaching a struggle between industry and government.”
