Yaakov Yitzchak Rabinowicz preached an elitist, rationalistic Hasidism that centered on Talmudic study and formed a counterpoint to the miracle-centered Hasidism of Lublin. His immediate successor, Simcha Bunim of Peshischa, brought Peshischa to its highest point and kickstarted a counter-revolutionary movement which challenged the Hasidic norm. While under the leadership of Rabinowicz, Peshischa was closer to a philosophy whereas, under Simcha Bunim it was transformed into a religious movement. Under Simcha Bunim's leadership, centers were created across Poland that held ideologically alliance to Peshischa. These centers preached Simcha Bunim's ideals of rationalism, radical personhood, independence and the constant quest for authenticity. He outwardly challenged the dynastic nature of Hasidic rebbes, which led to several unsuccessful attempts by contemporary Hasidic leadership to excommunicate Peshischa. After his death in 1827, Peshischa split into two factions, those of his more radical followers who supported Menachem Mendel of Kotzk as Simcha Bunim's successor and those of his less radical followers who supported the succession of Simcha Bunim's son Avraham Moshe Bonhardt. However, after Avraham Moshe's death a year later in 1828, the community almost unanimously followed Menachem Mendel, who gradually incorporated most of the community into Kotzk. After his death in 1859, Peshischa ceased to exist as a separate movement, yet its ideals still exist as the foundation for a large percentage of modern Hasidism.[1][2]
