Zechariah Dhahiri
Zechariah (Yaḥya) al-Ḍāhirī (, , b. "circa" 1531 – d. 1608), often spelled Zechariah al-Dhahiri () (16th century Yemen), was the son of Saʻīd (Saʻadia) al-Ḍāhirī, from Kawkaban, in the District of al-Mahwit, Yemen, a place north-west of Sana’a. He is recognized as one of the most gifted Yemenite Jewish poets and rabbinic scholars who left Yemen in search of a better livelihood, travelling to Calicut and Cochin in India, Hormuz in Persia, Basra and Irbīl in Babylonia, Bursa and Istanbul in Anatolia, Rome in Italy, Aleppo and Damascus in Syria, Safed and Tiberias, as well as Jerusalem and Hebron in the Land of Israel (then part of Ottoman Syria), Sidon in Ottoman Lebanon and Egypt, and finally unto Abyssinia where he returned to Yemen by crossing the Erythraean Sea and alighting at a port city near Mocha, Yemen. He wrote extensively about his travels and experiences in these places, which he penned in a Hebrew rhymed prose narrative, and eventually publishing them in a book which he called Sefer Ha-Mūsar ("The Book of Moral Instruction"), in circa 1580.
Al-Mutawakkil al-Mutahhar
Al-Mutahhar bin Muhammad was no immediate relative of the family that had provided imams for the last three generations. He was a descendant of the grand organizer of Zaydiyyah Islam, al-Qasim ar-Rassi (d. 860), in the 14th degree. When the old imam al-Mansur Ali died of the plague that ravaged Yemen in 1436, he was one of three candidates who brought forward their da'wa (call for the imamate). He took the honorific title al-Mutawakkil al-Mutahhar. The two other claimants were al-Mahdi Salah ad-Din (d. 1445) and al-Mansur an-Nasir (d. 1462). Of these, al-Mansur initially became the dominant, and imprisoned his two rivals. While al-Mahdi died in captivity, al-Mutawakkil was released by his captor after some time. In spite of the internal political disunity, the Zaidi community was relatively safe for incursions from the Sunni lowland of Yemen. The once powerful Rasulid Dynasty declined rapidly and collapsed altogether in 1442-1454. A new lowland power, the Tahiride Dynasty, took over in 1454. They did what they could to discomfort the Zaidi state from the beginning.
