Ballet in America emerged in the early 20th century, influenced by European traditions. The influx of European dancers and choreographers, especially during World Wars I and II, significantly contributed to its development. Government support and cultural exchange fostered growth. Key figures like George Balanchine, Lincoln Kirstein, and Agnes de Mille shaped American ballet. They established schools, companies, and innovative choreography. The rise of ballet coincided with the "American Century," a period of cultural and artistic growth in the United States.
