⚠ The office becomes hereditary

By the third generation the position of rebbe is passing from father to son, and by the nineteenth century the map of Eastern European Jewry is a map of courts — Ger, Belz, Sanz, Vizhnitz, Satmar, Bobov, Skver — each named for a town and each led by a family.

⚠⚠ No early Hasidic source requires this, and it is the clearest gap in the wing between theory and institution. The tzaddik doctrine is about a person's attainment; hereditary succession is about their father. ⭐ The movement is not unaware of the tension — the succession disputes are ferocious and several courts split permanently over them — but it has never resolved it, and Breslov's refusal is the only structural answer anyone gave.
