Bar Kokhba revolt
The name of the Revisionist Zionist youth movement Betar (בית"ר) refers to both the last Jewish fort to fall in the Bar Kokhba revolt, and to the slightly altered abbreviation of the Hebrew phrase "Berit Trumpeldor" or "Brit Yosef Trumpeldor" (ברית יוסף תרומפלדור), "lit." 'Joseph Trumpeldor Alliance'.
