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 Ibn 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 last just ruler and Imam of Yemen, but he obstinately persists in his aggressive policy by occupying our highlands in Tihamah, oppressing their inhabitants, and eradicating all who do not surrender to his rule.'"
