What was one thing Cornelius Vanderbilt did to gain control of his competitors?

In 1817, Vanderbilt went to work as a ferry captain for a wealthy businessman who owned a commercial steamboat service that operated between New Jersey and New York. The job provided Vanderbilt the opportunity to learn about the burgeoning steamship industry. In the late 1820s, he went into business on his own, building steamships and operating ferry lines around the New York region. Shrewd and aggressive, he became a dominant force in the industry by engaging in fierce fare wars with his rivals. In some cases, his competitors paid him hefty sums not to compete with them. (Throughout his life, Vanderbilt’s ruthless approach to business would earn him numerous enemies.)

In the 1840s, Vanderbilt constructed a large brick home for his family at 10 Washington Place, in Manhattan’s present-day Greenwich Village neighborhood. Despite his growing wealth, the city’s elite residents were slow to accept Vanderbilt, considering him rough and uncultured.

His route was faster than an established route across Panama, and much speedier than the other alternative, around Cape Horn at the southern tip of South America, which could take months. Vanderbilt’s new line was an instant success, earning more than $1 million (about $26 million in today’s money
