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). The second Saudi period was marked by less territorial expansion and less religious zeal, although the Saudi leaders continued to be called Imam and still employed Wahhabist religious scholars. Turki bin Abdullah bin Muhammad's reconquest of Riyadh from Egyptian forces in 1824 is generally regarded as the beginning of the Second Saudi State. Severe internal conflicts within the House of Saud eventually led to the dynasty's downfall at the Battle of Mulayda in 1891, between the forces loyal to the last Saudi imam, Abdul Rahman ibn Faisal ibn Turki, and the Rashidi dynasty of Ha'il. History The first Saudi to attempt to regain power after the fall of the Emirate of Diriyah in 1818 was Mishari bin Saud, a brother of the last ruler in Diriyah, Abdullah ibn Saud but he was soon captured by the Egyptians and killed. In 1824, Turki ibn Abdullah ibn Muhammad, a grandson of the first Saudi imam Muhammad ibn Saud who had managed to evade capture by the Egyptians, was able to expel Egyptian forces and their local allies from Riyadh and its environs and is generally regarded as the founder of the second Saudi dynasty as well as being the ancestor of the kings of modern-day Saudi Arabia. He made his capital in Riyadh and was able to enlist the services of many relatives who had escaped captivity in Egypt, including his son Faisal ibn Turki Al Saud. Turki was assassinated in 1834 by Mishari bin Abdul Rahman, a distant cousin. Mishari was soon besieged in Riyadh and later executed by Faisal, who went on to become the most prominent ruler of the Saudis' second reign. Faisal, however, faced a re-invasion of Najd organised by Mehmet Ali. The local population was unwilling to resist, and Faisal was defeated and taken to Egypt as a prisoner for the second time in 1838. The Egyptians installed Khalid bin Saud, last surviving brother of Abdullah bin Saud bin Abdulaziz, a great grandson of Muhammad bin Saud, had spent many years
