The second Zaydi state was established in 897 in the northern high¬lands of Yemen. It was initiated by Yahya bin al-Husayn bin al-Qasim al-Rasi bin Ismael bin Ibrahim bin al-Hassan bin Ali bin Abu-Talib (d. 911), who resided in Sa’dah and became the political leader of a Zaydi imamate state that continued until the middle of the twentieth century, when a military coup in 1962, supported by Nasser of Egypt, deposed the last Zaydi imam, Mohammad al-Badr. Yahya had arrived in Sa’dah from his hometown in al-Ras in Hijaz, invited by a Yemeni tribal delegation from Khawlan to mediate in bringing an end to years-long violence and fighting between the tribes of Bani Sa’ad and al-Roubayah in the Sa’dah region.
