This article examines the mobilization of the Israeli home front and the overseas volunteering movement that began in May 1967 and continued through the summer of 1968. The mobilization in the Six-Day War included manifestations of solidarity and volunteering in diverse fields. The Israeli government and the Histadrut sent volunteers to frontier communities and raised funds from the public to finance the war. The movement included World Jewry, which also participated in fundraising through an emergency campaign and sent thousands of volunteers to Israel.
