The kibbutz was renamed in memorial to Mordechai Anielewicz, who was the first commander of the Jewish Fighting Organization in the Warsaw Ghetto uprising.

[2] The statue of Anielewicz by Nathan Rapoport[3] clutching a grenade, next to the water tower which was destroyed by the Egyptians in May 1948, is a noted symbol of the kibbutz.

[4] After 1948, Yad Mordechai expanded on the land of the Palestinian village of Hiribya, which Israel depopulated during the 1948 Arab–Israeli War.

[5] During the 2023 Israel-Hamas war, in which more than 1,200 Israelis and foreigners were killed,[6][7][8] Hamas gunmen attempted to infiltrate the kibbutz.
