Zychlin (Hebrew: זיכלין) is a Hasidic dynasty originating from the town of Żychlin, Poland, where it was founded by Shmuel Abba Zychlinski (1809–1879).
[2] Reb Zelig was a relative of the Sabba Kadisha of Strikov, Reb Fishel, going to visit him and taking his young son Shmuel Abba with him.
Rabbi Shmuel Abba was known as the Ilui ("genius") of Luvitch and many scholars praised his depth and understanding.
Rabbi Shmuel Abba had a small following of Hasidim and lived at his father-in-law's house, but when he moved to Zychlin for monetary reasons he acquired a larger following.
Ninety-five percent of Zychliner Hasidim perished during the Holocaust, the last Rebbes dying at the hands of the Nazis.
