Explanation:

To put it into context during the last decades of the 1800s the United States passed from the Gilded Age, a time in which industrial businessmen took advantage of the lack of regulations about the matter and placed monopolies in almost every sector of the economy in the market.

After the Gilded Age, the United States moved to the Progressive Era. During that time, consciousness among the monopolies began to grow mostly because of muckrakers journalists that write about how the businessmen gain the monopolies.

In response to that the Sherman Antitrust Act was sanctioned. It was the first Act that regulates competition among enterprises in the nation. It explictly prohibit anticompetitive agreements and unilateral conducts that try to monopolize the market.
