Rabbi Mordechai of Bilgoray and his half-brother (through his father), Rebbe Aharon, escaped Europe in a daring escape attempt and arrived in Palestine in 1944. Both lost their wives and families to the Nazis. Both remarried in Israel; Rabbi Mordechai's second wife was Miriam, the daughter of Rabbi Hershel Glick of Satmar. Only Rabbi Mordechai had a child, Yissachar Dov. In November 1949 Rabbi Mordechai died suddenly and his son was raised by his uncle, Rebbe Aharon, who groomed him to be the next Rebbe in the dynasty.
For most of the year, Yissachar Dov lived near his uncle in Tel Aviv and studied in the Belzer Talmud Torah there; he spent the summer months in Jerusalem, studying in the Satmar Talmud Torah.
When Rebbe Aharon died in 1957, Yissachar Dov was only nine years old. For the next nine years, Belz was effectively without an active rebbe, as Yissachor Dov, then called the "Yanuka" (Child) by his followers, was educated by a small circle of trusted advisors. A few years after Rebbe Aharon’s death, Yissachar Dov entered the Belzer yeshiva in Jerusalem, where he was given two dormitory rooms – one which he shared with other students as a sleeping room and a private room where he could study alone and with others. Every decision regarding the young boy was brought before Rabbi Yaakov Yitzchak Neiman, Rav of the Belzer community in Montreal and a relative of Yissachar Dov on his mother’s side.
Yissachar Dov celebrated his bar mitzvah on 25 January 1961 (8 Shevat 5721) in the Tel Aviv beit medrash of Rebbe Aharon, where he sat by himself at the dais, greeting a few hundred guests. Back in yeshiva, he studied for many hours with private chavrusas (study partners) and prepared to receive rabbinic ordination. At the age of 15, he moved to an apartment which a group of Belzer Hasidim rented for him near the yeshiva, and began inviting other students to join him for Shabbat meals at which he delivered words of Torah and Hasidut.
At the age of 16, he was engaged to Sarah Hager, daughter of Rabbi Moshe Yehoshua Hager, then rosh yeshiva and av beis din (head of the rabbinical court) of Kiryat Vizhnitz, Bnei Brak (he succeeded his father as Vizhnitzer Rebbe in 1972). The wedding was held in February 1965 in Kiryat Vizhnitz, where the couple settled after their marriage.
In June 1966, a delegation of Belzer Hasidim approached Rokeach and urged him to accept the mantle of leadership for the Belz Hasidim. Rokeach asked them to seek the opinion of other Torah leaders, whereupon they solicited the approval of the Klausenberger Rebbe and the Gerrer Rebbe. The new Rebbe was coronated in Jerusalem on 28 July 1966. Standing at the gravesite of his uncle, the previous Belzer Rav, Rokeach received his first kvitel from the Yavrover Rav, a descendant of the Belzer and Ropshitzer Rebbes, as is customary in Belz. He has led the dynasty ever since.
He and his wife have one son, Aharon Mordechai Rokeach, born on 12 October 1975. Aharon Mordechai married Sarah Leah Lemberger, daughter of Rabbi Shimon Lemberger, Makova Rebbe in Kiryat Ata, on August 3, 1993 in Kiryat Belz, Jerusalem, in the presence of 60,000 people. The couple have ten sons and three daughters. On 21 May 2013 their eldest son, Sholom Rokeach, married Hana Batya Panneth (of the Nadvorna Hasidim in Bnei Brak) in a ceremony at the Belz Great Synagogue that was attended by tens of thousands of guests and well-wishers. With the birth of the young couple's daughter on 4 May 2014, the Rebbe became an elter zaida (great-grandfather).
The majority of Belzer Hasidim were killed in the Holocaust. Although some managed to immigrate to the United States and Israel, the post-war years saw the court of Belz's membership undergo a radical change, consisting largely of former members of other communities, or Haredim who had previously not belonged officially to any Hasidic group.
One of the new Rebbe's most important tasks was to take this diverse collection of followers and mold them into a unified community. He focused on building up Belz institutions, which were largely non-existent at the death of the previous Rebbe. As Belz slowly established an economic base, it began expanding its network of schools in Western Europe, America and Israel, as well as its yeshivas and its own Jerusalem enclave, Kiryat Belz. It also created its own newspaper, HaMachaneh HaCharedi, of which former MK Yisrael Eichler is a former editor.
Under the Rebbe's leadership, the Belz Hasidut has grown from a few hundred families in 1966 to over 7,000 families as of 2011. The Rebbe also oversees a global network of study halls, educational institutions, and chesed institutions.
The Rebbe has also invested heavily in Orthodox Jewish outreach with the founding of Yeshivas Torah V’Emunah, a ba'al teshuva yeshiva for men, and the Tzohar outreach organization for secular Jews.
While preserving the traditions established by his forebears, the Rebbe has also introduced new protocols to fit modern times. He was the first to bring professionals into the Hasidic educational system to diagnose and treat children with learning disabilities. He also encourages his Hasidim to develop their talents within the community, finding jobs for musicians, writers, managers, etc., within the hundreds of institutions and organizations that the Hasidut has established.
The Belzer Rebbe has long had a reputation for being a maverick in the Israeli Haredi community. The early years following his appointment as Rebbe saw him carefully forging alliances with other Hasidic courts (such as Ger and Vizhnitz), as well as the Misnagdic communities, particularly Degel HaTorah. He quickly became known as a political moderate and pragmatist, eventually even breaking what had earlier been something of a taboo: accepting funding and subsidies from the Israeli government.
As Belz began to establish itself as an independent and successful group, it began to attract some negative attention, particularly after the Rebbe's decision to accept money from the State. One group, the Edah HaChareidis, a coalition of several movements known for its strictness and traditionalism even among Haredim, took particular offense at the "renegades'" disregard of what had earlier been a largely unchallenged status quo. This was compounded by the Rebbe's willingness to participate in Israeli politics by encouraging his followers to vote and sending emissaries to join Haredi political parties. These disagreements turned from mere hostilities into a full-blown feud following the Rebbe's announcement in 1980 that Belz was going to split from the Edah HaCharedis.
Prior to the split, Belz had been the only non-Eidah member that accepted and supported the authority of the Badatz, the Edah's rabbinical court, whose authority touched all matters of everyday Haredi life, including kashrut certification. Early in the year, Rabbi Yitzchok Yaakov Weiss, the head of the Edah HaChareidis, issued a decree forbidding followers from sending their children to schools funded by State money. This represented a serious threat to Belz's moderate approach, which benefited greatly from State assistance.
In response, the Belzer Rebbe decided to cut his community off from the Edah HaCharedis and establish his own system of religious services, including kashrut certification. While Belz maintained that it was only interested in certifying food for its own community, the move was met with rancor by the Edah HaCharedis, particularly the Satmar Hasidim, who were both outraged at the Belzer Rebbe's defiance and concerned about Belz as potential economic competition.
This led to a large delegitimization campaign against the Rebbe. Later in the year, when he visited the United States, he was assigned a security detail by the FBI in response to multiple death threats. The conflict in Israel, initially confined to insulting posters, gradually escalated to a series of particularly offensive pranks and, ultimately, to physically violent clashes between followers. Neither the Belzer Rebbe nor Rabbi Weiss were ever involved in any of these activities, which are largely considered to have been the work of radical activists within both camps. Despite the opposition, Belz persevered, and tempers gradually cooled. While Belz and the Edah HaCharedis remain distant and implicitly hostile towards each other, the feud has, for all intents and purposes, ended.
In 2005 the Belzer Rebbe strongly encouraged his male followers to learn professions (specifically in white-collar work) during his annual Simchat Torah speech. He said,
Long-term students in yeshivas who are talented and have the economic means are fortunate, but students who year after year see that their studies are not going well, whether because of their skills or their economic situation, must learn a profession that earns a living. I'm not talking about getting rich but earning a living, so that one does not fall into debt. ... One can prepare for this in the yeshiva and devote a few hours a week in the evening to studying a profession.
The Belzer Rebbe's speech is the latest in a growing trend of encouraging Haredi men who would be more suited to work than study (or whose families are particularly financially needy) to join the workforce (see Torato Omanuto). The Rebbe's comments were noteworthy for their point that Orthodox Jews do not need to abandon their studies entirely in order to earn a living.
In 2015 leaders of the Belz community in London stated that in accordance with guidance from Belzer Rebbe, women driving vehicles was against traditional Belz rules of modesty. In conjunction with Belz educational leaders, a policy was introduced of not allowing pupils driven to school by their mothers to go into school.
Every Jew must firmly believe that inside him there resides a pure soul. Regardless of what his situation may be, even if he has strayed from the right path, the inner essence of his soul — which is a portion of God — remains pure and unsullied. ... From this tiny center of the soul that has not been tainted by evil, the transgressor derives the strength to do teshuvah (repentance), make amends for all his failings, and soar to the loftiest spiritual heights. (1991)
Everyone knows that the Arabs residing in Eretz Yisrael (the Land of Israel) — descendants of Ishmael — have only one aim: to drive the Jewish people out of Eretz Yisrael and to annihilate them. Now, when the Jewish people conduct themselves in the proper manner, the Arabs most certainly will have no power to harm them. To the contrary, the Arabs themselves will vanish from the scene. But even when Jews do not behave quite as they should, then the Holy One, Blessed be He, compares His nation with the nations of the world. And when viewed together, He finds that the Jewish people are the acme of perfection. ... For the Jewish people, when measured against the nations of the world, are absolutely flawless. In this merit, the Jewish people will defeat their enemies and crush them. (1990)
