Present Anbar, located on the east bank of the Euphrates, just south of the Nahr 'Isa, or Sakhlawieh canal, the northernmost of the canals connecting that river with the Tigris, had been founded circa 350 as Firuz Shapur, or Perisapora by Shapur II, Sassanid king of Persia.

Captured and destroyed by Emperor Julian in 363, but speedily rebuilt, Perisapora has become a refuge for the Arab, Christian, and Jewish colonies of this region.

Anbar is adjacent or identical to the Babylonian Jewish center of Nehardea, and lies a short distance from the present-day town of Fallujah, formerly the Babylonian Jewish center of Pumbedita.
