Key moment: Young people gather in Tempe, Ariz., in June to protest the Israel-Hamas war.
Historical significance: Protests over the Israel-Hamas war roiled college campuses beginning last fall. The rising death toll and the U.S. government’s financial support of Israel led to encampments and more than 2,500 arrests. Demonstrators also urged universities to jettison investments in Israel.
