“We knew how to share, to work together, to defer to one another, to

JASS was founded in 2016 and is directed by Professor Jonathan Schorsch, Chair for Jewish Religious and Intellectual History at the Universität Potsdam, Germany. He established JASS in the wake of the rise of openly nationalist, xenophobic, anti-democratic ruling parties in a disconcerting number of countries.


JASS’ mission is to serve Jewish (and non-Jewish) activists and organizations by offering programs, informed by Jewish values, that educate, train and challenge activists (protesters, social entrepreneurs, change-makers, innovators), in our shared fight for democracy, human rights and a healthy and sustainable world. 


JASS is unique in offering Jews and non-Jews alike a serious and practical education in Jewish traditional approaches to Tikkun Olam (repairing the world), historical examples of Jewish activism, and an interdisciplinary cluster of skills and methods applicable to any issue area. 


Meant to delve into the Jewish experience and fountains of wisdom, JASS invites non Jewish participants to take part in the program. We believe in the constructive power of dialogue and mutual understanding, and welcome allies of different views and experiences with open arms.
