History

Isfes (today called Yarbaşı) is identified with Hiaspis mentioned by the Roman historian Ammianus Marcellinus in the 4th century AD along the frontier with the Sasanian Empire. It was noted as the location of the defection of the protector domesticus Antoninus to the Sasanian Empire.

The Syriac Orthodox maphrian Basil Solomon took refuge at Isfes after having fled Mosul in 1514 and remained there until his death in 1518.

An attack by Muhammad Pasha of Rawanduz on Isfes resulted in the death of 80 men, including a priest and a notable, and the enslavement of a number of women and children in early 1834.

Amidst the Sayfo in 1915, the Assyrians of Isfes took refuge at Azakh where they were able to resist attacks from the Ottoman army and Kurds.

The Assyrian population of Isfes began to emigrate to Al-Malikiyah in Syria from 1960 onwards and eventually the last Assyrian family left in 1980.
