The outbreak of the First World War in August 1914 disrupted the established touring circuit, which included countries now on opposing sides, and caused a number of dancers, including Fokine, to return to their own countries. He moved to Sweden with his family in 1918 and later established his home in New York City , where he founded a ballet school (1921) and continued to appear with his wife, Vera Fokina. By 1924 he organized his first company the "American Ballet" which performed regularly at the Metropolitan Opera House, and toured the principal cities of the US. His first new creation for the company was the comedy Bluebeard , set to a score by Jacques Offenbach . In addition to his success in the United States, Les Sylphides was the first ballet ever presented at the American Ballet Theatre on January 11, 1940.
