After the Tanzimat (Reformation) period in the 19th century, characters in Turkish theatre were modernised and plays were performed on European-style stages, with actors wearing European costumes. Following the restoration of constitutional monarchy with the Young Turk Revolution in 1908, theatrical activities increased and social problems began to be reflected at the theatre as well as in historical plays. A theatrical conservatoire, Darülbedayi-i Osmani (which became the nucleus of the Istanbul City Theatres) was established in 1914. During the years of chaos and war, the Darülbedayi-i Osmani continued its activities and attracted the younger generation. Numerous Turkish playwrights emerged in this era; some of them wrote on romantic subjects, while others were interested in social problems, and still others dealt with nationalistic themes. The first Turkish musicals were also written in this period. In time, Turkish women began to appear on stage, which was an important development in the late Ottoman society. Until then, female roles had only been played by actresses who were members of Turkey's ethnic minorities. Today there are numerous private theatres in the country, together with those which are subsidised by the government, such as the Turkish State Theatres.
