Ibn Saud, the founder of Saudi Arabia, had named himself King of the Nejd, following the collapse of Ottoman Empire power during the Great War. In 1925 he took control of Hejaz from the Hashemites. In 1932, he proclaimed the merger of the Nejd and Hejaz Kingdoms, establishing the Saudi Arabian Kingdom. Most of the boundaries remained unmapped, unmarked, and undemarcated by treaty. He was described as "a modern Solomon", as "Cromwell of the Desert", and as both the Napoleon and the Bismarck of Arabia.
By 1932, Ibn Saud controlled almost all of Arabia, except for Yemen, and the smaller coastal states which were then British protectorates (Oman, Kuwait, Bahrein, Aden, etc.). Between Hejaz and Yemen were several tribal regions over which the Ottomans had previously held weak suzerainty, and which both Ibn Saud and the Imam of Yemen now aspired to control.
In 1923, Emir Idrissi, the ruler of the Emirate of Asir, maintained an uneasy independence between Nejd, Hejaz and Yemen. He was at peace with his traditional rivals in Hejaz, but in dispute with Imam Yahya of Yemen, to the south of Asir. The area controlled by the independent Idrisid emirate fluctuated during the ten years of its independent existence.
In 1926, the tribal ruler of Asir assented to Saudi suzerainty, and in 1930 it was incorporated into the Nejd and Hejaz Kingdom.
The war started when the new Saudi kingdom started growing at the cost of Yemeni-controlled areas, also known as Greater Yemen (Yemen proper and its three self-ruled Yemeni provinces: Al-Baha, Asir, Jazan and Najran).
Jizan is a coastal region on the Red Sea north of Yemen. Asir and Al-Baha are mountainous regions north of Yemen. Najran is a region further inland, north-east of Yemen. Asir and Jizan were both part of the Idrisid Asir emirate during the 1920s.
A treaty was made in 1931 but soon broken. In November 1933, the Yemenis advanced on Najran
A peace delegation sent by ibn Saud was jailed by King Yahya including the son of the Saudi king. This was the day when King Yahya said his famous saying: "Who is this bedouin coming to challenge my family's 900 year rule?" The king of Yemen then sent the Idrissi back to his lands with an army.
In February 1934, at the start of the war, the Yemen Government and the British representative in Aden made a "treaty of friendship", which resolved some of the disputes between Yemen and Britain over Aden and the border between Yemen and the Aden Protectorate, and under which the British guaranteed the independence of Yemen for forty years. The Imam agreed to stop attacking Aden. At this point in time, the British had a "treaty of friendship" with both the Saudi and Yemeni sides in the war.
In March 1934, King Ibn Saud ordered the Crown Prince of Arabia (later King Saud) "to re-occupy townships in the highlands of Tehama which the Iman of the Yemen has seized". A communique states that "Ibn Saud has tried all diplomatic means of seeking an agreement, but the Iman has persisted in a policy of oppressing the inhabitants and "eradicating" all who have not surrendered." There is little report of actual hostilities until May.
In May 1934, the Saudi forces pressed forward their attack in the coastal region, occupying Hodeida. The Wahabi tribesmen threatened to loot the Indian trading businesses in Hodeida, but were dissuaded by the arrival of British sailors to maintain order. Unrest occurred in Sanaa, due to lack of food. The Iman denied rumours that he had been slain, while his son fled. Both the King and the Imam sought control of Asir. The Imam asked King Fuad of Egypt to intervene in the war. The British sloop 'Penzance' evacuated the British and Indian residents of Hodeida, and 300 foreigners, to Karaman Island for safety. On May 6, three Italian warships were dispatched to Hodeida to protect Italian interests.
According to western newspaper reports: "Tehama is part of the principality of Asir, which maintained for a few years subsequent to the Great War a precarious independence between the territory of the Wahabi King Ibn Saud and that of the Imam of Yemen. In 1926 it accepted the suzerainty of Ibn Saud, and in 1930, under a new agreement, it was practically annexed by Ibn Saud. A dispute then arose between Ibu Saud and the Imam of Yemen regarding the frontier between Asir and Yemen, and this was believed to have been settled by a treaty concluded in December, 1931. In announcing his intention of taking action against Yemen, Ibn Saud's legation in London said: "The Saudi Government has tried all pacific means through diplomatic channels to come to an agreement with the Imam of the Yemen, but he obstinately persists in his aggressive policy by occupying our highlands in Tehama, oppressing their inhabitants, and eradicating all who do not surrender to his rule."
In May 1934, after capturing Hodeida, Saudi forces advanced towards Sanaa, where a battle was expected. The mountains were problematical for their armoured cars and tanks. Neither the British nor Italian forces in the region were expected to intervene. Although the Saudis had better weapons, including tanks, the Yemenis had more experience with mountain warfare. Although the dispute had been brewing for some time, British onlookers predicted that the result would be indecisive. The King demanded the abdication of the Iman, five years control of the border region, and the expulsion from Yemen of the former rulers of Asir.
By 10 May 1934, reports from the war were contradictory. Sanaa was reported to be in upheaval, although the Iman claimed to be in charge. The Yemenis retreated from Hodeida, but claimed to be winning in Najran. The Iman announced a bold plan to advance on Riyadh with 200,000 men, although this attack never eventuated.
On 12 May 1934, peace negotiations had commenced. The King dropped his demand for the Imam's abdication, but demanded a truce for at least 20 years. It was reported that the Crown Prince of Yemen supported the war, while his father the Imam was in favour of peace. The King claimed that he was not interested in taking over Yemen.
On May 26, it was reported that relations were tense and a re-outbreak of hostilities was likely. However, on 14 June 1934 it was reported that a Treaty had been signed between the King and the Imam guaranteeing 20 years of peace.
The Saudi's relinquished Hodeida and the Yemeni coast, but the other disputed areas were incorporated into Saudi Arabia. Jizan/Jizin, Asir, and Najran are today part of Saudi Arabia.
The war officially ended on 20 May 1934, with the signing of the Treaty of Taif, between ibn Saud and King Yahya, which asserted Yemens' sovereignty over territories (formerly) "in the possession of the Idrisis or the Al-Aidh, or in Najran, or in the Yam country" and these lands were rented for Saudi Arabia in return the Yemenis would enter Saudi Arabia freely and Najran, Asir and Jizan were to be returned to Yemen after 60 years. The total number of losses reached 2,100 by the end of the war.
The episode spurred Western powers to send warships to Hodeida to evacuate their nationals.
