The Black Gold Conspiracy — Rockefeller's Cleveland Secrets

🎭Your Mission

You are a private investigator, hired in Cleveland, 1888, by a powerful industrialist seeking to expose John D.

Rockefeller's past. In the 1870s,

Rockefeller and the Swift Rise of Standard Oil

« Je ne crois pas qu'il y ait une autre qualité aussi essentielle au succès de toute sorte que la qualité de la persévérance. Elle surmonte presque tout, même la nature. »
John D. Rockefeller

The Roots of an Industrial Empire

Cleveland, in the late 19th century, was a rapidly expanding city, a strategic crossroads for goods transportation. It was in this fertile context that John D. Rockefeller, a humble accountant, perceived the immense potential of oil. In 1870, he founded the Standard Oil Company of Ohio with partners like Henry Flagler. Their initial strategy was to acquire refineries and streamline the process, reducing production costs to an unprecedented level. Rockefeller distinguished himself by his long-term vision and rigorous management, transforming the nascent industry into a machine of efficiency.

The growth of Standard Oil was not without controversy. Through aggressive tactics, such as obtaining secret rebates on railway transportation (as with the South Improvement Company in 1872), the company gradually eliminated or absorbed its competitors. This horizontal and vertical integration allowed it to control nearly 90% of oil refining and distribution in the United States. While his methods were criticized for their monopolistic nature, Standard Oil's efficiency nonetheless helped make oil and its derivatives accessible to everyone, forever changing the American economic and social landscape.
