Rise to power

Following the capture of Riyadh, many former supporters of the House of Saud rallied to Ibn Saud's call to arms. He was a charismatic leader and kept his men supplied with arms. Over the next two years, he and his forces recaptured almost half of the Nejd from the Rashidis.

In 1904, Abdulaziz bin Mutaib Al Rashid appealed to the Ottoman Empire for military protection and assistance. The Ottomans responded by sending troops into Arabia. On 15 June 1904, Ibn Saud's forces suffered a major defeat at the hands of the combined Ottoman and Rashidi forces. His forces regrouped and began to wage guerrilla warfare against the Ottomans. Over the next two years, he was able to disrupt their supply routes, forcing them to retreat. However, in February 1905 Ibn Saud was named qaimmaqam of southern Nejd by the Ottomans which he held until 1913 when an Anglo-Ottoman agreement was signed. Ibn Saud's victory in Rawdat Muhanna, in which Abdulaziz Al Rashid died, ended the Ottoman presence in Nejd and Qassim by the end of October 1906. This victory also weakened the alliance between Mubarak Al Sabah, ruler of Kuwait, and Ibn Saud due to the former's concerns about the increase of Saudi power in the region.

Ibn Saud completed his conquest of the Nejd and the eastern coast of Arabia in 1912. He then founded the Ikhwan, a military-religious brotherhood, which was to assist in his later conquests, with the approval of local Salafi ulema. In the same year, he instituted an agrarian policy to settle the nomadic pastoralist bedouins into colonies and to replace their tribal organizations with allegiance to the Ikhwan.

In May 1914, Ibn Saud made a secret agreement with the Ottomans as a result of his unproductive attempts to get protection from the British. However, due to the outbreak of World War I, this agreement which made Ibn Saud the wali or governor of Najd was not materialized, and because of the Ottomans' attempt to develop a connection with Ibn Saud the British government soon established diplomatic relations with him. The British agent, Captain William Shakespear, was well received by the Bedouin. Similar diplomatic missions were established with any Arabian power who might have been able to unify and stabilize the region. The British entered into the Treaty of Darin in December 1915, which made the lands of the House of Saud a British protectorate and attempted to define the boundaries of the developing Saudi state. In exchange, Ibn Saud pledged to again make war against Ibn Rashid, who was an ally of the Ottomans.

The British Foreign Office had previously begun to support Hussein bin Ali, Sharif of Mecca and Emir of the Hejaz, by sending T. E. Lawrence to him in 1915. The Saudi Ikhwan began to conflict with Hussein in 1917, just as his sons Abdullah and Faisal entered Damascus. The Treaty of Darin remained in effect until superseded by the Jeddah conference of 1927 and the Dammam conference of 1952, during both of which Ibn Saud extended his boundaries past the Anglo-Ottoman Blue Line. After Darin, he stockpiled the weapons and supplies which the British provided him, including a 'tribute' of £5,000 per month. After World War I Ibn Saud received further support from the British, including a glut of surplus munitions. He launched his campaign against the Al Rashidi in 1920; by 1922 they had been all but destroyed.

The defeat of the Al Rashidi doubled the size of Saudi territory because, after the war of Ha'il, Ibn Saud sent his army to occupy Al Jouf and the army led by Eqab bin Mohaya, the head of the Talhah tribe. This allowed Ibn Saud the leverage to negotiate a new and more favorable treaty with the British in 1922, signed at Uqair. He met Percy Cox, British High Commissioner in Iraq, to draw boundaries and the treaty saw Britain recognize many of Ibn Saud's territorial gains. In exchange, Ibn Saud agreed to recognize British territories in the area, particularly along the Persian Gulf coast and in Iraq. The former of these were vital to the British, as merchant traffic between British India and the United Kingdom depended upon coaling stations on the approach to the Suez Canal.

In 1925, Ibn Saud's forces captured the holy city of Mecca from Sharif Hussein, ending 700 years of Hashemite rule. Following this he issued the first decree which was about the collection of zakat. On 8 January 1926, the leading figures in Mecca, Medina and Jeddah proclaimed Ibn Saud the King of Hejaz and the bayaa (oath of allegiance) ceremony was held in the Great Mosque of Mecca.

Ibn Saud raised Nejd to a kingdom as well on 29 January 1927. On 20 May 1927, the British government signed the Treaty of Jeddah, which abolished the Darin protection agreement and recognized the independence of the Hejaz and Nejd, with Ibn Saud as their ruler. For the next five years, Ibn Saud administered the two parts of his dual kingdom as separate units. He also succeeded his father, Abdul Rahman, as Imam.

With international recognition and support, Ibn Saud continued to consolidate his power. By 1927, his forces had overrun most of the central Arabian Peninsula, but the alliance between the Ikhwan and the Al Saud collapsed when Ibn Saud forbade further raiding. The few portions of central Arabia that had not been overrun by the Saudi-Ikhwan forces had treaties with London, and Ibn Saud was sober enough to see the folly of provoking the British by pushing into these areas. This did not sit well with the Ikhwan, who had been taught that all non-Wahhabis were infidels. In order to settle down the problems with the Ikhwan leaders, including Faisal Al Duwaish, Sultan bin Bajad and Dhaydan bin Hithlain, Ibn Saud organized a meeting in Riyadh in 1928, but none of them attended the meeting. Tensions finally boiled over when the Ikhwan rebelled. After two years of fighting, they were suppressed by Ibn Saud in the Battle of Sabilla in March 1929.

On 23 September 1932, Ibn Saud formally united his realm into the Kingdom of Saudi Arabia, with himself as its king. He transferred his court to Murabba Palace from the Masmak Fort in 1938 and the palace remained his residence and the seat of government until his death in 1953.

Ibn Saud had to first eliminate the right of his own father in order to rule, and then distance and contain the ambitions of his five brothers, particularly his brother Muhammad, who had fought with him during the battles and conquests that gave birth to the state.
