Koson (Hasidic dynasty)

Koson (, ) is a hasidic dynasty originating in the village of Koson (also Kossyny or Kaszony) in Ukraine. The dynasty was founded by Rabbi Yehosef Rottenberg in 1897. 
History.
"Bnei Shileishim".
Rabbi Yehosef Rottenberg was born in Halych in 1853 to Rabbi Tzvi Hirsh and Chaya Dreizya Rottenberg. He studied under Rabbi Chaim Halberstam of Sanz and Rabbi Yekusiel Yehuda Teitelbaum of Siget. Rabbi Yehosef married Rebbetzin Sara Yittel, the daughter of Rabbi Meshulim Feish Segal-Lowy I of Tosh and authored the "sefer" "Bnei Shileishem" (and is therefore sometimes referred to by its name). He settled in Koson in 1897 where he served as rebbe. After his death in 1911, he was succeeded as rebbe in Koson by his son, Rabbi Chaim Shlomo Rottenberg.
"Shmuah Tovah".
Rabbi Chaim Shlomo Rottenberg married Raitze, daughter of Rabbi Asher Yashaya Rubin of Kolbuszowa, Poland, and authored the "sefer" "Shmuah Tovah". In 1920 however, nine years after assuming the position of rebbe, Rabbi Chaim Shlomo died, and was succeeded by his younger brother (and son-in-law), Rabbi Yisrael Tzvi Rottenberg, known by the name of his "sefer", "Ohr Moleh".
"Ohr Moleh".
As Rebbe, the "Ohr Moleh" established a hasidic yeshiva, Yeshiva Ateres Tzvi, in Koson that attracted over a hundred students from throughout the region who came to study Torah for a year or more. For the "Yamim Tovim", many more chassidim would come to Koson to be with the rebbe. During World War II in 1944, the entire Jewish community of Koson was taken to the Beregszasz Ghetto in nearby Berehove, and soon after, they were deported to Auschwitz. The "Ohr Moleh" and all his children, save for one son-in-law, perished there.
Post World War II.
A third son of the "Bnei Shileishim" (and a brother of the "Shmuah Tovah" and the "Ohr Moleh"), Rabbi Moshe Shmuel Rottenberg served as a rabbi in Kleinvardein before emigrating to Los Angeles, and was recognized as the Kosoner Rebbe. His son, Rabbi Pinchas Shalom Rottenberg, served as Kosoner Rebbe in New York, as did his son after him, Rabbi Menachem Yisrael Rottenberg. He was succeeded by five sons: Rabbi Meir Yehosef in Brooklyn and later Linden, New Jersey; Rabbi Moshe Shmuel in London, England; Rabbi Naftali Tzvi; Rabbi Avraham Baruch in Lakewood Township, New Jersey; and Rabbi Chaim Yehuda Leib (Chaim Leibish) in Monsey.
Chanukah attack.
The Koson community came under the spotlight when an anti-Semitic machete attack occurred on Hanukkah, December 28, 2019, in the home of Rabbi Chaim Leibish Rottenberg, the Kossoner Rebbe of Monsey, New York. After the attack, New York Governor Andrew Cuomo said, standing outside Rabbi Rottenberg's home, "This is an intolerant time in our country. We see anger. We see hatred exploding. It is an American cancer on the body politic." Then-President Donald Trump called the attack "horrific" and said that "we must all come together to fight, confront, and eradicate the evil scourge of anti-Semitism."
Linden, New Jersey.
Rabbi Meir Yehosef Rottenberg, a son of Rabbi Menachem Yisrael Rottenberg, served as Kossoner Rebbe in Borough Park, Brooklyn before relocating his congregation to Linden, New Jersey. Although the community had started out very small, it grew quickly and currently includes families living in nearby Roselle, Cranford, Clark, and Rahway. After the opening of the Kosonner congregation, other Hasidic communities sprouted in Linden as well, including Bobov, Rachmastrivka, Pupa, and Satmar communities.
Israel.
The son of the "Shmuah Tovah", Rabbi Moshe Shmuel Rottenberg (also the first cousin of Rabbi Pinchas Shalom Rottenberg, Kosoner Rebbe of New York), served as a rabbi in Debrecen. He later emigrated to New York, where he became recognized as the Kozova Rebbe and in 1961, to Bnei Brak, Israel. His son, Rabbi Asher Rottenberg, continued the Kosoner dynasty in Bnei Brak (two of his other sons, Rabbis Yechiel Mechel and Chaim Shlomo Rottenberg, succeeded him as Kozova Rebbe).
Lineage of the Kosonner dynasty.
Included in the dynasty of the Kosoner Rebbes are the Kozova Rebbes, who descend from Rabbi Yehosef Rottenberg as well.
