Abdelaziz deposed his brother, Sheikh Humaid bin Rashid Al Nuaimi, in May 1841,[1] taking possession of Ajman fort. With popular support, Abdelaziz consolidated his position and was able to avoid any intervention from Humaid's father-in-law and close ally, Sheikh Sultan bin Saqr Al Qasimi, the Ruler of Sharjah.[2]
He received commendations from the British following an incident in 1845, when two vessels carrying rice tried to make Ajman port in a storm: one was wrecked at the entrance to the harbour, but the other managed to make the inner harbour, having lost part of its cargo. A number of men attempted to help themselves to the cargo of the partly wrecked boat, and Abdelaziz personally forced the crowd back at swordpoint, protecting both the cargo and crew.[3]
He led the forces of Ajman into battle with neighbouring Hamriyah in September 1848 and was killed in the action.[1] His brother Humaid bin Rashid succeeded him.
