Home Army members' attitudes toward Jews varied widely from unit to unit, and the topic remains controversial. The Home Army answered to the National Council of the Polish government-in-exile, where some Jews served in leadership positions (e.g. Ignacy Schwarzbart and Szmul Zygielbojm), though there were no Jewish representatives in the Government Delegation for Poland. Traditionally, Polish historiography has presented the Home Army interactions with Jews in a positive light, while Jewish historiography has been mostly negative. More recent scholarship has presented a mixed, ambivalent view of Home Army–Jewish relations. Both "profoundly disturbing acts of violence as well as extraordinary acts of aid and compassion" have been reported, though the majority of Holocaust survivors in an analysis by Joshua D. Zimmerman reported negative interactions with the Home Army.
