When ISIS swept into Mosul in June 2014, the organisation immediately began a campaign to wipe out the most important part of the northern Iraqi city’s unique heritage - its a multi-sectarian culture. Mosul was home to ancient and modern Christian communities, Yazidis, Shia and Sunni Muslims, and at one time, Jews. Throughout the period of ISIS occupation Omar Mohammad, a history lecturer at Mosul University, risked his life daily to get news of the city out to the world via the internet. His Mosul Eye blog became essential reading. Now living in exile in Europe, Omar de Mosul, as he is known, is reconstructing the history ISIS tried and failed to wipe out, including the history of the city’s Jewish community. Presenter Michael Goldfarb spends time with Omar as he collects oral histories from the remaining Jews who were born and grew up in the city. Most Jews left the city in the early 1950s in the upheaval following the establishment of Israel. He also speaks with Rabbi Carlos Huerta, retired US army chaplain, who spent the first year after the US overthrew Saddam Hussein in Mosul with the 101st Airborne. He had no idea about the rich Jewish history of the place and spent much of his time investigating it.
