On October 7, 2023, Hamas launched the deadliest attack on Jews since the Holocaust. For journalist Yardena Schwartz, the massacre was a chilling echo of the 1929 Hebron Massacre—the brutal slaughter of nearly 70 Jews, incited by propaganda that Jews sought to seize the Al Aqsa Mosque. At the time, she was writing her first book, "Ghosts of a Holy War: The 1929 Massacre in Palestine That Ignited the Arab-Israeli Conflict". Yardena shares how history repeated itself, how the October 7 attack reshaped her book, and why understanding the past is essential to making sense of the present.
