Joss Fritz

Joss Fritz (c.1470–c.1525) was a late fifteenth and early sixteenth century insurgent who lived in Germany. Full name Joseph Fritz, he was a serf from Untergrombach, Bruchsal.

Fritz was particularly active in the Upper Rhine area, organizing at least three major Bundschuh revolts, in 1502, 1512 and 1519. These revolts were all suppressed before they could take form, however, as he was repeatedly betrayed by fellow conspirators.
