Which company was formed by John D. Rockefeller in 1870? Standard Oil was incorporated in Ohio in 1870.

Rockefeller had entered the petroleum business in Cleveland during the 1860s. In 1870, he reorganized his earlier partnership into the Standard Oil Company of Ohio, with about $1 million in capital. His associates included Henry Flagler, Samuel Andrews, Stephen Harkness, and William Rockefeller.

Standard Oil expanded through refinery acquisitions, transportation agreements, pipelines, and tightly coordinated distribution. It became one of the most powerful businesses in the United States and helped make refined kerosene cheaper and more widely available. The company’s influence extended far beyond drilling: refining and transport were central to its strength.

A common mix-up is confusing Standard Oil with later companies such as Exxon, Mobil, Amoco, and Chevron. Those brands trace parts of their histories to Standard Oil subsidiaries created or separated after the company was broken up by the U.S. Supreme Court in 1911 under antitrust law.
