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. At the Uqair conference in 1922, the boundaries of Kuwait and Najd were set. Kuwait had no representative at the Uqair conference. Ibn Saud persuaded Sir Percy Cox to give him two-thirds of Kuwait's territory due to his de facto control of it. More than half of Kuwait was lost due to Uqair. After the Uqair conference, Kuwait was still subjected to a Saudi economic blockade and intermittent Saudi raiding.

Conquest of Ha'il, also referred as the Third Saudi–Rashidi War, was engaged by the Saudi forces with its ally Ikhwan tribesmen upon the Emirate of Ha'il (Jabal Shammar), under the last Rashidi rulers.

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
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 was sober enough to realize 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
