Not much is known of the Uyunids, except that they were the descendants of the Banu Abdul Qays tribe. They were involved in several internal disputes, causing the emirate to become unstable and eventually leading to the rise of the Bedouin Usfurids. The Usfurids saw a short period of stability. After overthrowing their former allies, the Uyunids, they had an uneasy relationship with the Persian rulers of Hormuz, who took control of the former Uyunid cities of Qatif and Bahrain around 1320 AD. This eventually led to the fall of the Usfurids. The region was mostly overlooked until the 1500s, when the Jabrids took over around 1507 AD, but they too fell due to internal conflicts in or around the 1540s.
