Operation Badr was the code name for the surprise attack launched by Egyptian forces against Israeli positions on October 6, 1973, marking the beginning of the Yom Kippur War. This military operation aimed to reclaim territory lost during the 1967 Six-Day War, particularly the Sinai Peninsula, and was executed on the holiest day in Judaism, Yom Kippur, taking the Israeli defense forces by surprise. The operation represented a pivotal moment in Arab-Israeli conflicts and highlighted shifts in military strategy and regional power dynamics.
