# Standard Oil Breakup (1911) On **May 15, 1911**, the U.S. Supreme Court ruled 8–1 in *Standard Oil Co. of New Jersey v. United States* that [[John D. Rockefeller]]'s oil monopoly constituted an "unreasonable" restraint of trade under the [[Sherman Antitrust Act]] and ordered its dissolution into **34 separate companies**. The decision was the **most consequential antitrust action in American history** — the event that established the principle that monopoly power is a legitimate concern of democratic government and that the state can break up private companies that have grown too powerful. ## What Happened **The case:** The federal government filed suit in 1906 under the Sherman Antitrust Act (1890), arguing that [[Standard Oil]] had monopolized the oil refining industry through predatory pricing, railroad rebate manipulation, and the trust mechanism. After years of litigation, the case reached the Supreme Court. **The ruling:** Chief Justice Edward White's opinion introduced the **"rule of reason"** — the standard that only "unreasonable" restraints of trade violated the Sherman Act. Standard Oil's practices (secret rebates, predatory pricing, industrial espionage, trust mechanism) were deemed unreasonable, and the Court ordered the company dissolved. **The dissolution:** Standard Oil was broken into 34 separate companies. The major successors and their modern descendants: | 1911 successor | Modern descendant | |---------------|-------------------| | Standard Oil of New Jersey (Esso) | **ExxonMobil** | | Standard Oil of New York (Socony) | **ExxonMobil** (via Mobil) | | Standard Oil of California (SoCal) | **Chevron** | | Standard Oil of Ohio (Sohio) | **BP** | | Standard Oil of Indiana (Amoco) | **BP** | | Continental Oil (Conoco) | **ConocoPhillips** | **The irony:** Rockefeller held shares in all 34 successor companies. Their combined stock value quickly exceeded the original company's value. The breakup made Rockefeller even richer. ## Why It Matters [[The Standard]] Oil case is the **origin point** for the permanent American debate about corporate power and government regulation: **What it established:** - The government can break up private monopolies - Monopoly power is a public concern, not just a private business matter - The Sherman Act has teeth — it's not just symbolic **The counter-reaction it provoked:** - [[Robert Bork]]'s *The Antitrust Paradox* (1978) argued antitrust should only concern "consumer welfare," not corporate power — effectively arguing against the Standard Oil precedent - The [[Chicago School]] revolution redefined antitrust to permit concentration as long as prices stayed low - The Reagan-era FTC and DOJ largely stopped enforcing antitrust, allowing the re-consolidation of industry - The [[Powell Memo]] (1971) was partly a plan to rebuild the intellectual legitimacy of the anti-regulation position that Standard Oil's excesses had discredited The through-line: **Standard Oil breakup (1911) → [[New Deal]] antitrust enforcement → Chicago School antitrust revolution (1970s-80s) → Reagan deregulation → re-consolidation → Big Tech monopoly debate (2020s) → DOGE as deregulation vehicle.** [[Ida Tarbell]]'s investigative exposé in *[[McClure's Magazine]]* (1902–04) — the [[Muckraking]] journalism that made the breakup politically possible — is also the template for every subsequent accountability journalism effort, from Watergate to the [[Panama Papers]]. ## See Also - [[John D.
