Ahmad bin Yahya
Murdered Hamidaddin ruler Imam Yahia was succeeded by his son Ahmad bin Yahya, while the Alwaziris were deposed. Ahmad's reign was marked by growing development, openness and renewed friction with the United Kingdom over the British presence in the south that stood in the way of his aspirations for the creation of Greater Yemen. In March 1955, a coup by a group of officers and two of Ahmad's brothers briefly deposed the king but was quickly suppressed.
