Anshan (or Anzan, Persian: انشان, modern: IZEH ایذه) was an ancient town in today's Iran in the province Khuzestan. The oldest settlement may have been as early as 5500 BC.
The town was one of the most important centers of the Elam empire.
Anshan was later ruled by the Achaemenid dynasty and became one of the centers of the Persian empire. The Persian prince Teispes (675-640 BC) conquered the city and called himself "king of the city of Anshan"
Anshan is a big archaeological place today containing around 200 hectares. Excavations carried out by the University of Pennsylvania took place in 1971, 1972, 1974, 1976 and 1978.
