埃及省
The Emirate of Nejd or Imamate of Nejd was the Second Saudi State, existing between 1824 and 1891 in Nejd, the regions of Riyadh and Ha'il of what is now Saudi Arabia. Saudi rule was restored to central and eastern Arabia after the Emirate of Diriyah, the First Saudi State, having previously been brought down by the Ottoman Empire's Egypt Eyalet in the Ottoman–Wahhabi War (1811–1818).
