The Klausenburger Rebbes are descended from Rabbi Chaim Halberstam of Sanz, who was a disciple of Rabbi Naftoli Tzvi of Ropshitz. Rabbi Naftoli was a disciple of Rebbe Elimelech of Lizhensk author of Noam Elimelech. Rebbe Elimelech was a disciple of Rebbe Dovber, the Maggid of Mezritch, the primary disciple of the Baal Shem Tov, the founder of Hasidism.
History
The Klausenburger dynasty was founded by Rabbi Yekusiel Yehudah Halberstam in 1927, when he assumed the position of Rav of Klausenburg, the capital city of Transylvania in western Romania. Halberstam was the great-grandson of Rabbi Chaim of Sanz, founder of the Sanz Hasidic dynasty. Rabbi Yekusiel Yehudah Halberstam grew up in Rudnik, Poland, and was known as a child prodigy and an excellent scholar. In the town of Klausenburg, which he led until the outbreak of World War II, he attracted many followers, and a great number of Sanz Hasidim began to follow the young Rebbe. As a result of the Holocaust, almost the entire community was destroyed. Approximately 15% survived the Holocaust, including the Rebbe, who lost his wife and eleven children. He emerged as a leader in the displaced persons camps in Europe as he created a communal survivors organization called She'aris Hapleitah, which operated religious schools for boys and girls and yeshivas for young men in 19 different DP camps, as well as a host of religious services. In 1947, he emigrated to America and established his court in the Williamsburg section of Brooklyn, where he began a widescale movement to increase Jewish observance. He founded many Jewish day schools and institutions of higher learning. He launched revolutionary programs for comprehensive study of the Talmud. He created a program called Mifal HaShas, in which students would master thirty folios of the Talmud in one month. His influence permeated areas as far as Canada, Mexico, and Israel. In 1957, he established the Kiryat Sanz neighborhood in the beachside city of Netanya, Israel. Over the next few years, he raised money for the establishment of girls' and boys' schools and yeshivas, an orphanage, an old-age home, and a hospital to serve this community. He moved to Kiryat Sanz in 1960. In 1968, he founded yet another Sanz community in Union City, New Jersey, and afterwards divided his time between that community and his residence in Netanya. Halberstam died on June 18, 1994, and was buried in Netanya. In his will, he divided leadership of the Klausenburger Hasidim between his two sons. His elder son, Zvi Elimelech Halberstam, became the Sanz-Klausenburger Rebbe of Netanya, and Shmuel Dovid Halberstam became the Sanz-Klausenburger Rebbe of Brooklyn.

In contrast to the custom among many Rebbes, the Klausenburger Rebbe did not take sons-in-law exclusively from rabbinic families; rather, he chose the best students of his yeshiva to marry his daughters. The only exception was Rabbi Shlomo Goldman, an accomplished Torah scholareven in his youth, who is the son of the previous Zhviller Rebbe in Israel. Other figures in Sanz-Klausenburg are:

Rabbi Aaron Weider, the Linzer Rav, was a long-standing dayan of the Sanz-Klausenburger rabbinical courtin America. His daughter Tzipora married Grand Rabbi Shmuel Dovid Halberstam
Harav Paskez Shlit"a, a long-time Rebbi in Yeshiva Torah Vadaas who was the Segan of HaRav Wieder, is the Dayan in Boro Park.
