The following charts illustrate the family of Rabbi Yisrael Baal Shem Tov, the founder of Hasidic Judaism.
The first chart shows the Baal Shem Tov's close family: his closest relatives, by blood and by marriage.
This is meant to clarify the various family relations mentioned in the Baal Shem Tov's biography.
The Baal Shem Tov did not found a Hasidic dynasty proper, as his immediate successor was his student, Rabbi Dov Ber of Mezeritch, and not any of his descendants.
Notably, his grandson R. Baruch of Mezhbuzh established his Hasidic court stressing that he was the sole heir of the Baal Shem Tov, a controversial issue in his time, which eventually distanced him from many of his colleagues, including R. Shneur Zalman of Liadi and R. Yaakov Yitzchak of Lublin.
