Egyptian bellydance

Raqs sharqi (Arabic: رقص شرقي‎‎, Egyptian Arabic: [ˈɾˤɑʔsˤe ˈʃæɾʔi]; literally "oriental dancing") is the classical Egyptian style of belly dance that developed during the first half of the 20th century.

Based on the traditional ghawazi and other folk styles and formed by western influences such as marching bands, the Russian ballet, Latin dance, etc., this hybrid style was performed in the cabarets of interbellum period Egypt and in early Egyptian cinema.

The style is often considered the classical style of belly dance, although that term historically referred to the ghawazi style, and today covers a much wider range of Middle Eastern dance as well as Western styles developed from them.

Raqs sharqi was developed by Samia Gamal, Tahiya Karioka, Naima Akef, and other dancers who rose to fame during the golden years of the Egyptian film industry. This has come to be considered the classical style of dance in Egypt by the 1950s. These dancers were famous not only for their role in Egyptian films, but also for their performances at the "Opera Casino" opened in 1925 by Badia Masabni. This venue was a popular place for influential musicians and choreographers from both the US and Europe, so many of the developments pioneered here can be considered new developments in the dance.
