The Mount of Olives Hoshana Rabbah ceremony was an annual Hoshana Rabbah gathering organized by the Palestinian Gaonate. Overlooking the Temple Mount from the Mount of Olives, a series of proclamations relating to the Jewish calendar and other matters were made before a crowd of Jews hailing from the Land of Israel and the diaspora, some coming as far as modern-day France and Germany. Attendance was seen as obligatory for those with the means to do so. The ceremony, in effect, reinforced the sovereignty and primacy of the Palestinian Gaonate over world Jewry. It most likely occurred from the late ninth or early tenth century to the late eleventh century, coinciding with the Palestinian Gaonate's presence in Jerusalem. Some sources, however, indicate earlier origins.
The gathering was a multi-part ceremony that began with circling the Mount of Olives seven times in song and prayer. After ascending the mount, the Gaon delivered a sermon. The remainder of the ceremony consisted of:
The ceremony was likely suspended between 1024 and 1029 due to the Jarrahid wars, which halted pilgrimage traffic across the region and brought severe hardship to Jerusalem's Jewish community. When the Hoshana Rabbah gathering finally resumed in the autumn of 1029, the atmosphere was highly volatile. During the festival, a group of Rabbanite pilgrims attempted to pressure the Gaon, Shelomo ben Yehuda, into issuing an excommunication against the Karaites, who were said to eat meat with milk. When he refused, the crowd turned on him, claiming he was bribed by the Karaites.
Eventually, these pilgrims were convinced to withdraw their demands due to the interventions of Muslim Fatimid rulers, with the support of the Gaon. To deter riots, the local governor of Jerusalem, Fath al-Qal'i, attended the 1029 and 1030 ceremonies in person, the latter time armed with lashes and chains to enforce the peace.
The ceremony largely ended with the Turkmen conquest of Jerusalem in the 1070s, with the Gaonate moving north to Tyre. Attempts to perform this ceremony in Tyre in 1081 and Haifa in 1082 failed to draw pilgrims.
