The Siege of Ctesiphon took place in 27 April 629 between the forces of Shahrbaraz and Ardashir III. Shahrbaraz managed captured Ctesiphon with a small force, demonstrating to all the weakness of the Sasanian Empire.

Background

In 602, the last Byzantine-Sasanian war began, it was the most devastating of the series of wars fought between the two empires. In 618, Khosrau II sent Shahrbaraz to conqueror Egypt, one year later the Sasanians managed to capture Alexandria, the capital of Byzantine Egypt. After the fall of Alexandria, the Sasanians gradually extended their rule southwards along the Nile. By 621, the province was securely in Sasanian hands.

Egypt would remain in Sasanian hands for 10 years, run by general Shahrbaraz from Alexandria. As the new Roman emperor, Heraclius, reversed the tide and defeated Khosrau II, Shahrbaraz was ordered to evacuate the province, but refused. In the end, Heraclius, trying both to recover Egypt and to sow disunion amongst the Iranians, offered to help Shahrbaraz seize the Sasanian throne for himself. An agreement was reached, and in the spring of 629, the Sasanian troops began leaving Egypt.

Siege

Luckily for Shahrbaraz, a civil war began in 628 that divided the resources of the Sasanian Empire, and a devastating plague in the western provinces killed half of the population along with Kavadh II, weakening the empire. Shahrbaraz marched towards Ctesiphon with 6,000 men, besieged it and then captured it, betraying the Sasanian nobles and killing many of them, including two notable ones named Ardabīl and Mah-Adhur Gushnasp.

Aftermath

After capturing Ctesiphon, Shahrbaraz killed Ardashir III, and took the throne for himself. However, his reign did not last long, because he was killed by Sasanian nobles after forty days, and two daughters of Khosrau II reigned in succession.
