During World War II, 20,000 to 30,000 Jews fought back against the Nazis as partisans. Hidden deep in the forests, these underground communities were the heart of an organized resistance movement that took up arms against the Nazis. Around 10 percent of these partisans were women.

Although often known for their support roles—performing camp duties, providing medical care, and acting as messengers—some women also fought alongside men. As we close out Women’s History Month, we’re celebrating three Jewish women partisans whose bravery shows us the meaning of what it is to be an upstander.

Today, on Yom HaShoah Ve'Hagevurah, or Holocaust and Heroism Remembrance Day, we give pause to remember the six million Jews and the five million other targeted individuals who were murdered during the Holocaust. But we can also celebrate moments of bravery. Resistance has been tied into this commemoration from its inception in Israel in the 1950s.
