The resident dance company of Roudaki Hall Opera House in Teheran. It was founded in 1958 and sponsored in part by the Iranian Ministry of Culture and Arts, under the artistic direction of Nejad Ahmadzadeh, with his wife Aida as leading ballerina. It began with a dozen dancers and by 1978 had expanded to 46, one-third being Iranian. The repertory had works by Ailey and Cullberg as well as several classics. Heaton staged Giselle in 1970 and Coppélia in 1971 and Chabukiani mounted Swan Lake in 1970–1. Ahmadzadeh was succeeded in 1977 by Ali Pourfarrokh. It was dissolved after the revolution of 1979; however in 2007 Nima Kiann founded the Swedish-based company Les Ballet Persans, also known as the New Iranian National Ballet, which attempted to resurrect the spirit of the defunct company, with material mixing Western ballet and Iranian cultural traditions.
