'Abd ar-Rahman of Bornu

ʽAbd ar-Rahman bin Muhammad al-Amin al-Kanemi (died December 1854), sometimes called Abdurrahman or Darman, was briefly the shehu (ruler) of the Kanem–Bornu Empire from 1853 to 1854. He was the son of shehu Muhammad al-Amin al-Kanemi, the founder of the al-Kanemi dynasty, and the younger brother of shehu Umar Kura. A skilled military commander, ʽAbd ar-Rahman played an important role in defending Bornu against external threats, including an 1846 invasion by the Wadai Sultanate, as well as an in the empire's expansion.

ʽAbd ar-Rahman's reputation for cruelty and ambition, as well as his rivalry with the waziri (vizier) al-Hajj Bashir, led to deep divisions at the imperial court in Kukawa. ʽAbd ar-Rahman deposed his half-brother Umar Kura in a coup d'état and ruled for less than a year before being overthrown and executed.
