Solomon ben David (Hebrew: שלמה בן דוד) was a Karaite leader of the late tenth and early eleventh centuries CE. He was the son of David ben Boaz. As a direct lineal descendant of Anan ben David, he was regarded as nasi and resh galuta of the Karaite community. He was succeeded by his son Hezekiah ben Solomon.
The Karaite Jewish University is a non-profit corporation incorporated in California, U.S.A., in November 2005 for the purposes of disseminating the study of Karaite Judaism. Karaite Jewish University is not accredited as an academic institution. However, it has been authorized by the Council of Sages of Universal Karaite Judaism to teach an Introduction to Karaite Judaism course, both for Rabbinic Jews wishing to affiliate formally with Karaite Judaism, as well as potential converts to Judaism according to Karaite practice. Universal Karaite Judaism is the official body recognized by the State of Israel as representing Karaite Jews in matters of personal status. The university's first “Introduction to Judaism” class began in February 2006 and ended in May 2007. Ten of the graduates from the course converted to Judaism together with their children under the auspices of Congregation Bnai Israel of the Karaite Jews of America in Daly City, California, on July 30, 2007. These were the first official sanctioned conversions to Judaism according to the Karaite rite since 1465. On September 2, 2007, the university awarded an Honorary Doctorate degree in Education to Mourad El-Kodsi, historian and author of The Karaite Jews of Egypt and The Karaites of Poland, Lithuania, Russia & Ukraine. El-Kodsi was named Dean Emeritus of the university whose function will be to mentor the university's graduate students.
The Karaite Synagogue (Hebrew: Kal Ha Kadosh Be Kushta Bene Mikra or in Turkish: Karahim Sinagogu, Karaim Sinagogu, Karayim Sinagogu) is a Kenesa in the Hasköy district of Beyoğlu, Istanbul, Turkey. The building's date of construction is unclear; it may date to Byzantine times. The building was in ruins in the sixteenth century; it was repaired in 1536, burned in 1729, rebuilt, burned again in 1774, rebuilt between 1776 and 1780, restored in 1842, and burned again in 1918. The Karaite congregation of the town also has their own cemetery. The trust behind these Institutions is called Hasköy Türk Karaim Musevi Sinagogu Vakfı. Today the Kenesa functions only at the Karaite Pesach. Contact to the congregation can be built via the Turkish Chief Rabbinate or the Quincentennial Foundation Museum of Turkish Jews.
The Letter of the Karaite elders of Ascalon (c. 1100) was a communication written by six elders of the Karaite Jewish community of Ascalon and sent to their coreligionists in Alexandria nine months after the fall of Jerusalem during the First Crusade. The contents describe how the Ascalon elders pooled money to pay the initial ransom for pockets of Jews and holy relics being held captive in Jerusalem by the Crusaders, the fate of some of these refugees after their release (including their transport to Alexandria, contraction of the plague, or death at sea), and the need for additional funds for the rescuing of further captives. It was written in Judeo-Arabic, Arabic using the Hebrew alphabet.
Jacob ben Reuben (יעקב בן ראובן) was a Karaite scholar and Bible exegete of the eleventh century. He wrote a brief Hebrew language commentary on the entire Bible, which he entitled Sefer ha-'Osher, because, as he says in the introduction, the reader will find therein sufficient information, and will not need to have recourse to the many voluminous commentaries which the author himself had consulted. The book is, in fact, merely a compilation; the author's explanation of any given passage is frequently introduced by the abbreviations or (i.e., Arabic "ma'nahu" or "ya'ni" = "that is to say"); and divergent explanations of other commentators are added one after the other and preceded by the vague phrase ("another says"). It is, in fact, chiefly an extract of Yefet ben Ali's work, from whom Jacob borrowed most of his explanations as well as the quotations from various authors, chiefly on the Pentateuch. But Jacob also drew upon later Karaite authors, the last of whom is Jeshua ben Judah, who, so far as is known, flourished about 1054 (see Harkavy, Hadashim gam Yeshanim, vii. 17). This date points to the second half of the eleventh century as the date of composition of the Sefer ha-'Osher.
