How did Rockefeller and the Standard Oil Company get around laws that?

Rockefeller and Standard Oil used tactics such as creating monopolies, undercutting competitors' prices, forming secret alliances, and engaging in predatory pricing to gain dominance in the oil industry. They also used aggressive litigation strategies to challenge and delay enforcement of antitrust laws. Ultimately, their actions led to the passage of antitrust legislation like the Sherman Antitrust Act in 1890 to regulate monopolistic practices.
