Anti-government rebels marched into an American Mormon colony in Mexico July 12, 1912, giving the inhabitants 24 hours to surrender all their weapons. Hostility to US influence was a major component of the mass revolutionary movement that erupted in 1911 against the longstanding rule of dictator Porfirio Diaz.
By the time of Diaz’s ouster, 22 percent of Mexico’s land area owned by American investors or “pioneers.” Power in Mexico was concentrated in the small group of metropolitan and foreign investors. William Randolph Hearst alone owned between 6,600,000 and 7,500,000 acres in Sonora, Tehuantepec, Chihuahua as well as other properties. http://www.wsws.org/articles/2012/jul2012/twih-j09.shtml#100
