Shahrbaraz (also spelled Shahrvaraz or Shahrwaraz; New Persian: شهربراز), was shah (king) of the Sasanian Empire from 27 April 630 to 9 June 630.

This word is rendered as Shahrbarāz (شهربراز) in New Persian and as Sarvaros (Greek: Σαρβάρος; Latin: Sarbarus) in Byzantine sources.

[4][5] The title is also mentioned as Rasmiozdan, Rasmiozan (Georgian), rsmysa (Arabic: رسميسة, reading uncertain), Rōmēzān, Rūmīzān, Rumbūzān (al-Tabari, Tarikh).

During Shahrbaraz's later life, he joined the Sasanian army, where he rose to high offices, and was appointed as spahbed of Nēmrōz.

He was married to the sister of the Sasanian king Khosrow II, Mirhran, with whom Shahrbaraz had one boy named Shapur-i Shahrvaraz.

One of the most important events during his career was when he led the Sasanian army towards Palaestina, and after a bloody siege captured Jerusalem, a city sacred to the Christians.

In a mere seven days, he bypassed Mount Ararat and the 200 miles along the Arsanias River to capture Amida and Martyropolis, important fortresses on the upper Tigris.

[27] Shahrbaraz, along with a smaller army, later managed to slip through Heraclius' flanks and bee-lined for Chalcedon, the Sasanian base across the Bosphorus from Constantinople.

[23] The army of Shahrbaraz stationed themselves at Chalcedon, while the Avars placed themselves on the European side of Constantinople and destroyed the Aqueduct of Valens.

[28] Because of the Byzantine navy's control of the Bosphorus strait, however, the Sasanians could not send troops to the European side to aid their ally.

Patrician Bonus' galleys rammed and destroyed the Slavic boats; the Avar land assault from 6 to 7 August also failed.

[34][35] Disappointed by Shahrbaraz's failure, Khosrow II sent a messenger bearing a letter to Kardarigan, who was the second-in-command of the Sasanian army.

[36] Shahrbaraz then changed the contents of the letter, making it state that Khosrow II wanted 400 officers killed, ensuring that Kardarigan and the rest of the army remained loyal to him.

[37] Shahrbaraz then moved his army to northern Syria, where he could easily decide to support either Khosrow or Heraclius at a moment's notice.

Still, with the neutralization of Khosrow's most skilled general, Heraclius deprived his enemy of some of his best and most experienced troops, while securing his flanks prior to his invasion of Iran.

Sheroe then proclaimed himself as king of the Sasanian Empire on 25 February, assuming the regnal name of Kavadh II.

[41][42] Following the loss of territory required for the peace treaty, the embittered aristocracy started forming independent states within the Sasanian Empire.

Furthermore, dams and canals became derelict, and a devastating plague erupted in the western provinces of Iran, killing half of the population along with Kavad II, who was succeeded by Ardashir III.

[45] He was, however, unable to capture the city, and then made an alliance with Piruz Khosrow, the leader of the Parsig (Persian) faction, and the previous minister of the Empire during the reign of Ardashir's father, Kavad II.

[50] Forty days later, 9 June 630, during a ceremony, Shahrbaraz was killed by a javelin thrown by Farrukh Hormizd, who then helped Boran, the daughter of Khosrow II, to ascend the throne.

In the Islamic period, it was transferred into the legend of Umar ibn al-Numan and his sons which became included in the One Thousand and One Nights, itself influencing the late Byzantine epic of Digenes Akritas.
