The Italian Empire was the first to recognize Imam Yahya as the King of Yemen in 1926. This created a great deal of anxiety for the British, who interpreted it as recognition of Imam Yahya's claim to sovereignty over Greater Yemen, which included the Aden protectorate and Asir. The Idrisis turned to Ibn Saud seeking his protection from Yahya Muhammad Hamid ed-Din. However, in 1932, the Idrisis broke their accord with Ibn Saud and went back to Imam Yahya seeking help against Ibn Saud himself, who had begun liquidating their authority and expressed his desire to annex those territories into his own Saudi domain. Imam Yahya demanded the return of all Idrisi dominion. That same year, a group of Hejazi liberals fled to Yemen and plotted to expel Ibn Saud from the former Hashemite Kingdom of Hejaz, which had been conquered by the Saudis seven years earlier. Ibn Saud appealed to Britain for aid. The British government sent arms and aeroplanes . The British were anxious that Ibn Saud's financial difficulties may encourage the Italian Empire to bail him out. Ibn Saud suppressed the Asiri rebellion in 1933, after which the Idrisids fled to Sana'a. Negotiations between the Imam Yahya Hamid ed-Din and Ibn Saud proved fruitless. After the 1934 Saudi-Yemeni war, Ibn Saud announced a ceasefire in May 1934. Imam Yahya agreed to release Saudi hostages and the surrender of the Idrisis to Saudi custody. Imam Yahya ceded the three provinces of Najran, Asir, and Jazan for 20 years. and signed another treaty with the British government in 1934. The imam recognized the British sovereignty over Aden protectorate for 40 years. Out of fear for Hudaydah, Yahya did submit to these demands. According to Bernard Reich, Professor of Political Science and International Affairs at George Washington University, Yahya could have done better by reorganizing the Zaydi tribes of the northern highlands as his ancestors did against the Turks and British intruders and turn the lands they captured into another graveyard.
