Experimental theatre (also known as avant-garde theatre) began in Western theatre in the late 19th century with Alfred Jarry and his Ubu plays as a rejection of both the age in particular and, in general, the dominant ways of writing and producing plays. The term has shifted over time as the mainstream theatre world has adopted many forms that were once considered radical.
Like other forms of the avant-garde, it was created as a response to a perceived general cultural crisis. Despite different political and formal approaches, all avant-garde theatre opposes bourgeois theatre. It tries to introduce a different use of language and the body to change the mode of perception and to create a new, more active relation with the audience.
