During this time, Duke was repeatedly sued by business partners and shareholders. In 1906, the American Tobacco Company was found guilty of antitrust violations, and was ordered to be split into four separate companies: American Tobacco Company, Liggett & Myers, R. J. Reynolds, and the P. Lorillard Company. In 1911, the U.S. Supreme Court upheld an order breaking up the American Tobacco Company's monopoly. The company was then divided into several smaller enterprises, of which only the British-American Tobacco Company remained in Duke's control.
