Around the mid-19th century, over a hundred dynastic courts related by marriage were the main religious power in the territory enclosed between Hungary, former Lithuania, Prussia and inner Russia, with considerable presence in the former two. In Central Poland, the pragmatist, rationalist Przysucha school thrived: Yitzchak Meir Alter founded the court of Ger in 1859, and in 1876 Jechiel Danziger established Alexander. In Galicia and Hungary, apart from Halberstam's House of Sanz, Tzvi Hirsh of Zidichov's descendants each pursued a mystical approach in the dynasties of Zidichov, Komarno and so forth. In 1817, Sholom Rokeach became the first "Rebbe" of Belz. At Bukovina, the Hager line of Kosov-Vizhnitz was the largest court.
