Yom Yerushalayim
The 28th of Iyar — commemorating the reunification of Jerusalem in the Six-Day War of 1967.
Summary. Yom Yerushalayim ("Jerusalem Day"), 28 Iyar, commemorates the reunification of Jerusalem in the Six-Day War of June 7, 1967 / 28 Iyar 5727. From 1948 to 1967, the Old City of Jerusalem (including the Western Wall and the Temple Mount) was under Jordanian control and inaccessible to Jews; on that morning, Israeli paratroopers under Motta Gur captured the Old City. The radio broadcast of Motta Gur's words — "Har HaBayit b'yadeinu!" ("The Temple Mount is in our hands!") — and the subsequent prayer at the Western Wall by Israeli Chief Rabbi Shlomo Goren and General Rabbi Goren's shofar blowing are among the iconic moments of modern Jewish history.
Historical Context
In the lead-up to the Six-Day War (May–June 1967), Egypt, Syria, and Jordan threatened the destruction of Israel; massive Arab armies mobilized on Israel's borders. Israel launched preemptive air strikes on June 5, destroying the Egyptian Air Force on the ground. Over the next six days, Israel defeated the combined forces of Egypt, Syria, and Jordan, capturing the Sinai Peninsula, the Golan Heights, Judea and Samaria (the West Bank), Gaza, and (most religiously significant) the Old City of Jerusalem with the Western Wall. The Israeli paratroopers' capture of the Old City on June 7 / 28 Iyar is the day commemorated.
The Religious Significance
For 19 years (1948–1967), Jews had been forbidden access to the Western Wall and to the Old City. The Jordanian government desecrated the ancient Jewish cemetery on the Mount of Olives, destroyed dozens of synagogues in the Old City Jewish Quarter, and used Jewish gravestones as paving for military latrines. The capture of the Old City restored Jewish access. For Religious Zionists, this was unmistakably miraculous — a fulfillment of the ancient prayers for the return to Jerusalem. The Chief Rabbinate of Israel established Yom Yerushalayim as a holiday with full Hallel and a special liturgy.
Observance
Modern Orthodox and Religious Zionist communities observe Yom Yerushalayim with festive liturgy: Hallel, the special Haftarah, the prayer for the State of Israel, the prayer for the IDF, and substantial communal celebration. In Israel, the day includes the Yom Yerushalayim Flag March — a massive procession of religious Zionist youth through the Old City, ending at the Western Wall. The march has become controversial in recent years, particularly the portion that passes through the Muslim Quarter. Israeli Haredi communities are largely abstainers from Yom Yerushalayim observance. Diaspora observance is most active in Modern Orthodox and Religious Zionist settings.
Where Denominations Diverge
Modern Orthodox and Religious Zionist communities observe with full liturgy. Conservative observance varies. Reform congregations often note the day. Haredi observance is largely absent.
