Background
Al-Hasan bin Izz ad-Din was the son of the forceful imam al-Hadi Izz ad-Din.
Al-Hasan bin Izz ad-Din was the son of the forceful imam al-Hadi Izz ad-Din.
After the death of the latter in 1495, al-Hasan proclaimed his call for the imamate under the name an-Nasir al-Hasan. He inherited his father's love for learning, but hardly his political skills. Nevertheless, an-Nasir al-Hasan could only control a limited area in the northern highlands.
For many years he had to resist the rival imam al-Mansur Muhammad (d 1505). Al-Mansur was captured and poisoned by the Tahiride Sultan Amir in 1504, and the Tahirides seized San'a. In later years, an-Nasir al-Hasan was eclipsed by a new powerful imam, al-Mutawakkil Yahya Sharaf ad-Din (r 1506-1555).
He died in obscurity in 1523 and was buried in Falala. He sired nine sons, Muhammad, Izz ad-Din, Majd ad-Din, Da'ud, Ahmad, Salah, Yahya, Taj ad-Din, and Ali. Majd ad-Din made his call for the imamate after his father's demise, but was unsuccessful and died in 1536 without ever holding political power.
