The siege of Dara was raised by the Sasanian king Khosrow I in 573 during the Byzantine–Sasanian War of 572–591.

[3] The Sasanians cut through a hill to divert the city's water supply,[4] and used captured Roman ballistae from the abandoned Roman Siege of Nisibis (573).

[5] The news of the fall of Dara, long a major Byzantine stronghold in Upper Mesopotamia, drove Emperor Justin II insane.

[3] Bahram Chobin was commander of the cavalry force in the siege, and was promoted to the spahbed of the North after this victory.
