Some historians believe the war reduced and weakened the Christian population not just in Jerusalem but across the Near East, allowing the success of the following Arab invasion. However, over the past thirty years the archaeological evidence has not supported the ancient manuscripts which record the devastation of the Christian community in Jerusalem.^{[19]: 353}

Jerusalem is said to have been burnt down. However, neither wide spread burning nor destruction of churches have been found in the archaeological record.^[8][7] Despite the claims of large scale destruction, the archaeological evidence does not reveal layers of destruction associated with the Persian conquest.^[8] There was also no hard evidence found for the widespread destruction of churches.^[8]

A significant number of burial sites were allocated according to Strategius. A mass burial grave at Mamilla cave was discovered in 1989 by Israeli archeologist Ronny Reich, near the site where Strategius recorded the massacre took place. The human remains were in poor condition containing a minimum of 526 individuals.^[20] Other mass burial sites have also been found although they cannot be accurately dated to the Persian conquest of Jerusalem.^[8] Yet, excavations of Jerusalem show a continuous habitation in Jerusalem neighborhoods and essentially little impact of population during the period of Persian governorship. As stated by archaeologist Gideon Avni:

... all excavated sites in Jerusalem show a clear pattern of continuity, with no evidence for destruction by the Persian conquest of 614 or the Arab conquest of 636.^[8]

Demographic continuity might have resulted from population exchange by the victorious Jewish rebels, but apparently also the Christian habitation remained relatively constant, despite the disturbance by the Persian conquest, and no significant impact on the population of Jerusalem was made during the following period of Sassanid dominance.^{[8] [19]: 353}
