The various Hasidic groups may be categorized along several parameters, including their geographical origin, their proclivity for certain teachings, and their political stance. These attributes are quite often, but by no means always, correlated, and there are many instances when a "court" espouses a unique combination. Thus, while most dynasties from the former Greater Hungary and Galicia are inclined to extreme conservatism and anti-Zionism, Rebbe Yekusiel Yehudah Halberstam led the Sanz-Klausenburg sect in a more open and mild direction; and though Hasidim from Lithuania and Belarus are popularly perceived as prone to intellectualism, David Assaf noted this notion is derived more from their Litvak surroundings than their actual philosophies.
