The Residence Of Imam Yahya, Dar Al-Hajar Stone House, Wadi Dhar, Sana, Yemen

Due to conflicting tribes in the border areas between Saudi Arabia, and Yemen that escalated a war ensued that was ended in 1934 in the signing of the Taif treat between Saudi Arabia and Yemen. The treaty was the basis for the final territorial agreement between both countries concluded during the reign of King Fahd bin Abdulaziz, and President Ali Saleh.
Internal policy
From 1934 until his assassination in 1948, Yahya redirected his energies toward internal consolidation of his authority and the creation of a viable central government, answerable to him personally . To this end, control of the hinterland was strengthened by the establishment of a standing army and the naming of his sons as governors of key provinces. Tighter control over affairs in San'a, the capital, was assured by extending the scope of administrative functions and appointing other sons as supervisors of old and new political institutions . The regime sent Yemen's first students abroad : military cadets to Iraq in the 1930s and civilian students, the "Famous Forty," to Lebanon in the late 1940s . An early attempt was made to introduce some direction to the nascent national economy by the establishment of a Yemen trading company.
