Persian dance
Persian dance refers to the dance styles indigenous to Iran. Genres of dance in Iran vary depending on the area, culture, and language of the local people, and can range from sophisticated reconstructions of refined court dances to energetic folk dances. The population of Iran includes many ethnicities, such as Kurds, Azerbaijanis, Turkmen, Jews, Armenian, Georgian peoples, in addition to numerous Iranian tribal groups which can be found within the borders of modern-day Iran. Each group, region, and historical epoch has specific dance styles associated with it. Raghs (also spelled as Raqs) is the Arabic word for dance, and is almost exclusively the word used for dance in Persian, as the Persian word for dance, paykubi, is no longer in common usage. It's also the word in Azerbaijani for dance (Reqs). The Kurdish word for dance is Halperke, and the Lurs from Lorestan use the word Bākhten (or Bāzee) for dance.
The earliest researched Persian dance is a dance worshiping Mithra (as in the Cult of Mithras) in which a bull was sacrificed. This cult later became highly adhered in the Roman Empire. This dance was to promote vigor in life. Ancient Persian dance was significantly researched by Greek historian from Herodotus of Halikarnassos, in his work Book IX (Calliope), in which he describes the history of Asian empires and Persian wars until 478 BC. Ancient Persia was occupied by foreign powers, first Greeks, then Arabs, and then Mongols and in turn political instability and civil wars occurred. Throughout these changes a slow disappearance of heritage dance traditions occurred.
