The largest sect in the world, with some 26,000 member households, which constitute 20% of all Hasidim, is Satmar, founded in 1905 in the namesake city in Hungary and based in Williamsburg, Brooklyn, and Kiryas Joel. Satmar is known for its extreme conservatism and opposition to both "Agudas Israel" and Zionism, inspired by the legacy of Hungarian Ultra-Orthodoxy. The sect underwent a schism in 2006, and two competing factions emerged, led by rival brothers Aaron Teitelbaum and Zalman Teitelbaum. The second-largest "court" worldwide, with some 11,600 households (or 9% of all Hasidism), is Ger, established in 1859 at Góra Kalwaria, near Warsaw. For decades, it was the dominant power in "Agudas", and espoused a moderate line toward Zionism and modern culture. Its origins lay in the rationalist Przysucha School of Central Poland. The current Rebbe is Yaakov Aryeh Alter. The third-largest dynasty is Vizhnitz, a charismatic sect founded in 1854 at Vyzhnytsia, Bukovina. A moderate group involved in Israeli politics, it is split into several branches, which maintain cordial relations. The main partition is between Vizhnitz-Israel and Vizhnitz-Monsey, headed respectively by Rebbes Israel Hager and the eight sons of the late Rebbe Mordecai Hager. In total, all Vizhnitz sub-"courts" constitute over 10,500 households. The fourth major dynasty, with some 7,000 households, is Belz, established 1817 in namesake Belz, south of Lviv. An Eastern Galician dynasty drawing both from the Seer of Lublin's charismatic-populist style and "rabbinic" Hasidism, it espoused hard-line positions, but broke off from the Edah HaChareidis and joined "Agudas" in 1979. Belz is led by Rebbe Yissachar Dov Rokeach.
