Yigal Amir attended a Haredi elementary school in Herzliya and a high school yeshiva in Tel Aviv. He then joined the Israel Defense Forces as a Hesder student, combining army training in the Golani Brigade with religious study at Yeshivat Kerem B'Yavneh.

Amir was a law and computer science student at Bar-Ilan University and a right-wing radical who had strenuously opposed Rabin's signing of the Oslo Accords. During his studies at Bar-Ilan University, he was active in organizing protest rallies.
