Another important consideration with the editors in deciding that the Standard Oil Trust was the best adapted to illustrate their meaning, was the fact that it is one of the very few business organisations of the country whose growth could be traced in trustworthy documents. There is in existence just such documentary material for a history of the Standard Oil Company as there is for a history of the Civil War or the French Revolution, or any other national episode which has divided men’s minds. This has come about largely from the fact that almost constantly since its organisation in 1870 the Standard Oil Company has been under investigation by the Congress of the United States and by the Legislatures of various states in which it has operated, on the suspicion that it was receiving rebates from the railroads and was practising methods in restraint of free trade. In 1872 and again in 1876 it was before Congressional committees, in 1879 it was before examiners of the Commonwealth of Pennsylvania and before committees appointed by the Legislatures of New York and of Ohio for investigating railroads. Its operations figured constantly in the debate which led up to the creation of the Interstate Commerce Commission in 1887, and again and again since that time the Commission has been called upon to examine directly or indirectly into its relation with the railroads. In 1888, in the Investigation of Trusts conducted by Congress and by the state of New York, the Standard Oil Company was the chief subject for examination. In the state of Ohio, between 1882 and 1892, a constant warfare was waged against the Standard in the courts and Legislature, resulting in several volumes of testimony. The Legislatures of many other states concerned themselves with it. This hostile legislation compelled the trust to separate into its component parts in 1892, but investigation did not cease; indeed, in the last great industrial inquiry, conducted by the Commission appointed by President McKinley, the Standard Oil Company was constantly under discussion, and hundreds of pages of testimony on it appear in the nineteen volumes of reports which the Commission has submitted.
