Saudi take over of Riyadh In 1901,
Abdulaziz, the son of the last emir of the
Second Saudi state,
Abdul Rahman bin Faisal, later known as
Ibn Saud, asked the Emir of
Kuwait, where the family had been living in exile since the fall of the second Saudi state to the
Ottomans and the
Rashidis, for men and supplies to attack
Riyadh. Already involved in several wars with the Rashidis, the Emir agreed to the request and provided Ibn Saud with horses and arms. Although the exact number of men fluctuated during the subsequent journey, he is believed to have departed with around 40 men. In January 1902, Ibn Saud and his men reached Riyadh. With only a small force, he believed the only viable way to take the city was to capture
Masmak fort and kill Ibn Ajlan, the chief of Riyadh. After achieving these objectives, they successfully seized the city during a night raid. With the capture of his family's ancestral home, Ibn Saud demonstrated that he possessed the qualities necessary to be a
sheikh or
emir: leadership, courage, and luck. This marked the beginning of the
Third Saudi state. Ibn Saud's dominions became known as the
Emirate of Riyadh, which lasted until 1921.
Saudi–Rashidi War The Saudi–Rashidi War, also referred as the "First Saudi–Rashidi War" or the "Battles for Qasim", was engaged between the Saudi loyal forces of the newborn Sultanate of Nejd versus the Emirate of Ha'il (Jabal Shammar), under the Rashidis. The warfare period of sporadic battles ended with Saudi takeover of the
Al-Qassim Region, after decisive victory in Qasim on 13 April 1906, though other engagements followed into 1907.
Al-Hasa and Qatif In 1913, Ibn Saud, with support from the
Ikhwan,
conquered al-Hasa from an Ottoman garrison which had controlled the area from 1871. He then integrated al-Hasa and
Qatif into the Emirate. The people in these areas were
Shia, whereas the Saudis were Sunni Wahhabi puritans, resulting in harsh treatment for
Shi'a Muslims in Saudi Arabia, as opposed to the relatively tolerant treatment by
Sunni Ottomans. The sharpened conflict between Kuwait and
Najd led to the death of hundreds of Kuwaitis. The war resulted in sporadic border clashes throughout 1919–1920. Following Kuwait–Najd War,
Ibn Saud imposed a tight trade blockade against Kuwait for 14 years from 1923 until 1937. The goal of the Saudi economic and military attacks on Kuwait was to annex as much of Kuwait's territory as possible. The emir was powerless to repel those raids by himself, thus the British maintained a military base, with a small
air force, at Marka, close to
Amman.
Second Nejd–Hejaz War The Saudi conquest of Hejaz was a campaign, engaged by Saudi Sultan
Abdulaziz Al Saud to take over the Hashemite
Kingdom of Hejaz in 1924–1925. The campaign successfully ended in December 1925, with the fall of Jeddah. Subsequently, in 1926, Abdulaziz was proclaimed king of Hejaz, and raised Nejd to a kingdom as well in 1927. For the next five-plus years, the Saudi domains were referred to as the
Kingdom of Nejd and Hejaz, though they were administered as separate units.
Ikhwan rebellion army in
Ikhwan Revolt against the alliance of the
British Empire,
Kuwait and
Ibn Saud As Saudi expansion slowed in the 1920s, some among the Ikhwan pushed for continued expansion, particularly to the British-controlled territories such as
Transjordan to the north - where the
Ikhwan raided in 1922 and 1924. By this time, the few parts of central Arabia that hadn't been overrun by the Saudi-Ikhwan forces had treaties with Britain, and Abdulaziz had realized the folly of a potential conflict with the British. However, the Ikhwan had been taught that all non-Wahhabis were infidels.
Faisal al-Dawish of the
Mutair tribe and
Sultan bin Bajad of the
Otaiba tribe, the leaders of the Ikhwan, were among those who accused Abdulaziz of going "soft", with the former reportedly telling the latter that the Saudis were "as much use as camel bags without handles". A
rebellion erupted, climaxing in a
battle at Sabillah, which some have labeled a massacre but pro-Saudi sources consider to have been a fair fight. Additional battles erupted through 1929 in Jabal Shammar and in the vicinity of the Awazim tribe. The rebellion was put down in 1930, with the surrender of last opposition elements. Though the survivors were jailed, their descendants remained opposed to Saudi rule, and one such descendant,
Juhayman al-Otaibi, would gain infamy in 1979 when he led the
Grand Mosque Seizure.
Proclamation of the Kingdom of Saudi Arabia From 1927 to 1932, Ibn Saud administered the two main portions of his realm, Nejd and the Hejaz, as separate units. On 23 September 1932, Ibn Saud proclaimed the union of his dominions into the Kingdom of Saudi Arabia. Ibn Saud's eldest son
Saud became
crown prince in 1933. ==Aftermath==
