Content:  Zachariah was a Khagan of the Khazars, reported in the account of St. Cyril. The dates of his reign are unknown but he was khagan during Cyril's visit to Khazaria in 861.
Title: Zachary of Georgia
Content:  Zachary, born Zakaria Jorjadze (ზაქარია ჯორჯაძე), was the Catholicos–Patriarch of the Georgian Orthodox Church in the period 1623&ndash;1632. Before that Zachary was the bishop of Nekresi in 1613&ndash;1623 and was the bishop of the Georgian royal Bagrationi dynasty.
Title: Serach (Khazar)
Content:  In the Schechter Letter, Serakh is the wife of the Khazar ruler Sabriel. A Jew, she encourages her husband and other Khazars to convert to Judaism and establish it as the official religion of Khazaria. Serakh is not mentioned in the Khazar Correspondence or the Kuzari. Some scholars have postulated that the Khazar conversion to Judaism came as a result of contact with existing Jewish populations in the Crimea and the Caucasus, possibly the ancestors of the Krymchaks or Mountain Jews. As with so much of Khazar studies, the absence of documentary evidence renders the question of whether Serakh belonged to one of these groups a matter of speculation.
Title: Khazar Correspondence
Content:  The Khazar Correspondence is a set of documents, which are alleged to date from the 950s or 960s, and to be letters between Hasdai ibn Shaprut, foreign secretary to the Caliph of Cordoba, and Joseph Khagan of the Khazars. The Correspondence is one of only a few documents attributed to a Khazar author, and potentially one of only a small number of primary sources on Khazar history. The authenticity of the correspondence has been challenged, on the grounds that it has little in common with the otherwise attested chronology, language, borders and economy of the Khazars at the time. Ostensibly it gives both account of the Khazar conversion to Judaism and of its progress in subsequent generations, as well as potentially showing that within a generation of the fall of the Khazar empire in 969, the Khazar state was still militarily powerful and received tribute from several polities.
Title: Schechter Letter
Content:  the Khazar kingdom matches up with no Muslim, Jewish or Byzantine source from the period regarding wars of migration. It also differs radically from every other alleged source on the Khazar conversion to Judaism and in its naming of the ruling class. The names of the figures involved, Sabriel being the name of an angel in the Jewish mystical tradition, Serah being a biblical figure and the claim of descent from the tribe of Simeon whose demise is chronicled in the bible, strongly indicate the text is an unreliable source and heavily influenced in a rich Jewish tradition of wish fulfilment and mystical writing about the ten lost tribes of Israel.
Title: Az-Zakariyya
Content:  A tomb, dating from the early Iron Age, has been excavated here. Among the pottery found in the grave was a figurine, representing Astarte. A town called Beit Zacharia (var. Kefar Zacharia) existed on the hill in Roman times, from whence the village takes its name. According to Sozomen, the body of the prophet Zachariah was found here in 415 C.E. and a church and monastery were established. The village was under the administrative jurisdiction of Bayt Jibrin. On April 29, 1309 (=Dhu al-Qa’da 18, in the Hijri year 708), in  the early Mamluk era, two representatives from Az-Zakariyya; Farraj bin Sa‘d bin Furayj and Nassar bin ‘Amara bin Sa‘id; promised that the revenues of Az-Zakariyya should go to the Dome of the Rock and the Al-Aqsa Mosque. However, by the end of Mamluk era, the village was a dependency of Hebron, and formed part of the waqf supporting the Ibrahimi Mosque. In the 1480s C.E. Felix Fabri described how he stayed in a "roomy inn", next to a "fair mosque" in the village.
Title: Khazar Correspondence
Content:  been given to Jews attached to a Croat embassy, and reached Khazaria via yet another messenger, Isaac ben Eliezer of Nemetz (Germany). Joseph's alleged reply gives an account of Khazar history and of its current (c. undefined 960) sociopolitical and economic status. He further invites Hasdai to come to Khazaria, an invitation that Hasdai probably never accepted. The Correspondence has survived in three slightly variant versions over the centuries. Historian Shaul Stampfer has questioned the authenticity of letter said to have been received from the Khazar King, citing numerous linguistic and geographic oddities amid a flourishing of pseudo-historiographic texts and forgeries in medieval Spain. The text, written in literary Hebrew, with many Arabic 
Title: Zechariah in Islam
Content:   According to the Islamic doctrine, Zakarīya (زكريا, Zechariah) is a prophet and messenger of God (Allah), and a father of the prophet Yahya. Zakariya was a righteous priest and prophet of God whose office was in the Second Temple in Jerusalem. He would frequently be in charge of managing the services of the temple and he would always remain steadfast in prayer to God. As he reached his old age, Zakariya began to worry over who would continue the legacy of preaching the message of God after his death and who would carry on the daily services of the temple after 
Title: Zechariah of Israel
Content:  Zechariah (זְכַרְיָה Zəḵaryāh, meaning "remembered by Yah"; also Zachariah, Zacharias; Zacharias) was the fourteenth king of the northern Israelite Kingdom of Israel, and son of Jeroboam II. Zechariah became king of Israel in Samaria in the thirty-eighth year of Azariah, king of Judah. William F. Albright has dated his reign to 746 BC &ndash; 745 BC, while E. R. Thiele offers the dates 753 BC &ndash; 752 BC. The account of his reign is briefly told in 2 Kings. According to the Bible, Zechariah did what was evil in the Lord's sight, as the previous kings of Israel since Jeroboam I had done. Zechariah ruled Israel for only six months before Shallum, a captain from his own army, murdered him and took the throne. This ended the dynasty of Jehu after four generations of his descendants, fulfilling the prophecy in.
Title: Khazars
Content:  The earliest surviving Arabic text that refers to Khazar Jewishness appears to be that of ibn Rustah, a Persian scholar who wrote an encyclopedic work on geography in the early tenth century. It is believed that ibn Rustah derived much of his information from the works of his contemporary Abu al Jayhani based in Central Asia. Christian of Stavelot in his Expositio in Matthaeum Evangelistam (c. 860–870s) refers to Gazari, presumably Khazars, as living in the lands of Gog and Magog, who were circumcised and omnem Judaismum observat—observing all the laws of Judaism. New numismatic evidence of coins dated 837/8 bearing the inscriptions arḍ al-ḫazar
