The Emirate of Al Humaid ceased to exist in 1796 after the defeat of Barak bin Abdul Mohsen [ar] at the hands of the First Saudi State.
[2] Under Barrak ibn Ghurayr [ar] of the Al Humaid, the Bani Khalid were able to expel Ottoman forces from the cities and towns in 1670 and proclaim their rule over the region.
[3][4] Ibn Ghurayr made his capital in Al-Mubarraz (in present-day eastern Saudi Arabia), where remnants of his castle stand today.
[4] According to Arabian folklore, one chief of the Bani Khalid attempted to protect the prized desert bustard (Habari) from extinction by prohibiting the bedouin in his realm from poaching the bird's eggs, earning the tribe the appellation of "protectors of the eggs of the Habari", an allusion to the chief's absolute supremacy over his realm.
[5] The Bani Khalid of eastern Arabia maintained ties with members of their tribe who had settled in Nejd during their earlier migration eastwards, and also cultivated clients among the rulers of the Najdi towns, such as the Al Mu'ammar of al-Uyayna.
