American vaudeville (1850–1920) The migrations of mixed theatrical forms

The origins of the American vaudeville stand in the intersection of various theatrical types, which came from Europe in the 18th century. The case-study of 19th-20th century San Francisco theatre proves that the repertories of the European troupes, migrating to the Unites States, mainly exported a mixed dramaturgy. So, the American variety theatre appears as the result of the interaction between the European and the local performance practices and traditions.
