Modern dance is a broad genre of western concert or theatrical dance, primarily arising out of Germany and the United States in the late 19th and early 20th centuries.
Modern dance is often considered to have emerged as a rejection of, or rebellion against classical ballet. Socioeconomic and cultural factors also contributed to its development. In the late 19th century, dance artists such as Isadora Duncan, Maud Allan, and Loie Fuller were pioneering new forms and practices in what is now called aesthetic or free dance for performance. These dancers disregarded ballet’s strict movement vocabulary, the particular, limited set of movements that were considered proper to ballet, and stopped wearing corsets and pointe shoes in the search for greater freedom of movement.
Throughout the 20th century, sociopolitical concerns, major historical events, and the development of other art forms contributed to the continued development of modernist dance in the United States and Germany. Moving into the 1960s, new ideas about dance began to emerge, as a response to earlier dance forms and to social changes. Eventually, postmodern dance artists would reject the formalism of modern dance, and include elements such as performance art, contact improvisation, release-technique, and improvisation.
