At the turn of the 20th century, Rockefeller built Standard Oil through aggressive expansion and operational efficiency. His control over refining, pipelines, and distribution allowed him to dominate the oil industry and accumulate unprecedented capital.

During this era, regulatory frameworks were limited, and antitrust enforcement was weak, enabling him to consolidate power and wealth on a scale rarely seen before or since. This environment shaped public perception and later policy responses.
