Upper Harbor
The Upper Harbor was a port in the Harbiyah district of Baghdad in the 9th century, located northeast in the Khuld subdistrict.
History
In the 860s, the Hidden One Basim Ibn Ishaq travelled to the harbor to locate Beshi, Ali ibn Muhammad's second-in-command within the Zanj rebels that Nur had contact with. Contrary to what Basim expected, Beshi had no clue of Ali's whereabouts and was preparing to rescue the rebels who were being held prisoner at the harbor by the Caliphate guards. Basim helped Beshi to free the rebels, who then revealed Ali had been captured alongside them but had been separated from the group and sent to another site. One of the rebels showed Basim the mark drawn on Ali's arms before Beshi led his men to regroup at the Water Mill outside the city.[1]
Sometime after this event, Basim returned to the Upper Harbor to perform an assassination contract on Ali's behalf. Bashim located his target, who was a slave merchant arranging a shipment of human cargo and, as per Ali's wishes, burned him alive for the atrocities he had committed.[2]
