The Principality of Najran was a state that existed in the Arabian peninsula from 1633 to 1934. It originated as an Islamic ecclesiastic principality under Yemeni suzerainty in 1633, although it later came under Ottoman influence.[3] Najran opposed a Yemeni rebellion against the Ottomans in the 1880s.[4] In the Saudi-Idrisi treaty of 1920, the Emirate of Nejd and Hasa officially laid claim to the territories of Najran, and in 1921 the Ikhwan militia invaded Najran.[5] The Mutawakkilite Kingdom of Yemen also had ambitions in Najran, and thus attempted its own conquest in 1924.[1] In the winter of 1931/1932, Yemeni forces once again attempted to take Najran, but were expelled by the Saudis in 1932.[6] In November 1933, Yemeni forces occupied Najran.[7] In 1934, following the Saudi-Yemeni War, Najran's independence definitively ended when Yemen renounced its claims to Najran and the principality was annexed into Saudi Arabia.[1]
