The National Association of Attorneys General was founded in 1907 initially to create a forum for state attorneys general to discuss a common approach to antitrust issues related to the Standard Oil Company. Since then, antitrust efforts have consistently been a core aspect of the attorney general’s role.

Antitrust laws are based on the proposition that strong competition among different firms is best for the economy as a whole and results in the best prices and quality for consumers. In addition to federal statutes, including the Sherman Antitrust Act of 1890 and the Clayton Antitrust Act of 1914, almost every state has similar laws that prohibit price-fixing and monopolization. Attorneys general have the ability to enforce both federal and state antitrust laws on behalf of the state and its citizens, both individually and as part of a multistate group.
