Peshawar ( Pashto: پېښور Pekhawar/Peshawar, Hindko: پِشور Pishor, Urdu: پشاور), is the capital of the Khyber-Pakhtunkhwa and the administrative centre (but not the capital) for the Federally Administered Tribal Areas of Pakistan. The Kushan king Kanishka, moved the capital from Pushkalavati (now called Charsadda in the Peshawar valley) to Purushapura in the 2nd century CE. The current name "Peshawar" may derive from the Sanskrit Purushapura (meaning "city of men") and is known as Pekhawar or Peshawar in Pashto and Pishor in Hindko. The area originally belonged to Gandhara and the eastern Iranian tribes of Scythian origin and later became part of the Kushan Empire. It gave its name to the Peshwari naan bread, one of the diverse types of naan common in the curry houses of Great Britain. Briefly it also witnessed some Greek influence after which it saw the Arab conquest and rise of Islam. Today it is one of the prime cities of Pakistan west of the river Indus.
