Hamdanid dynasty
Under Harun's command, the Kharijites continued their activities in the area around Mosul. They subdued numerous villages and rural districts adjacent to the Tigris River, putting deputies over these territories and levying taxes and tithes from the inhabitants. Harun also established an alliance with Hamdan ibn Hamdun, a Taghlibite chieftain and the eponymous founder of the Hamdanid dynasty, and over the course of the next several years the two leaders jointly conducted a number of campaigns within the Mosul district.
