73 years later, the Nakba remains central to Palestinian national identity and political aspirations, as evidenced by the 2018-19 Gaza March of Return and even the recent protests in Jerusalem. However, despite being a core Palestinian grievance, the Nakba continues to be whitewashed or denied outright by pundits, lobbyists, and even policymakers.
Commemoration of the day has been taught by Arab citizens of Israel who were internally displaced as a result of the 1948 war has been practiced for decades, but until the early 1990s was relatively weak. Initially, the memory of the catastrophe of 1948 was personal and communal in character and families or members of a given village would use the day to gather at the site of their former villages. Small scale commemorations of the tenth anniversary in the form of silent vigils were held by Arab students at a few schools in Israel in 1958, despite attempts by the Israeli authorities to thwart them. Visits to the sites of former villages became increasingly visible after the events of Land Day in 1976.
As early as 1949, one year after the establishment of the State of Israel, 15 May was marked in several West Bank cities (under Jordanian rule) by demonstrations, strikes, the raising of black flags, and visits to the graves of people killed during the 1948 war. These events were organized by worker and student associations, cultural and sports clubs, scouts clubs, committees of refugees, and the Muslim Brotherhood. The speakers in these gatherings blamed the Arab governments and the Arab League for failing to "save Palestine". By the late 1950s, 15 May would be known in the Arab world as Palestine Day, mentioned by the media in Arab and Muslim countries as a day of international solidarity with Palestine.
In the wake up of the failure of the 1991 Madrid Conference to broach the subject of refugees, the Association for the Defense of the Rights of the Internally Displaced in Israel was founded to organize a March of Return to the site of a different village every year on 15 May so as to place the issue on the Israeli public agenda.
By the early 1990s, annual commemorations of the day by Palestinian Arab citizens of Israel held a prominent place in the community's public discourse.
It is believed that Israeli Arabs taught the residents of the territories to commemorate Nakba Day. Palestinians in the occupied territories were called upon to commemorate 15 May as a day of national mourning by the Palestine Liberation Organization's United National Command of the Uprising during the First Intifada in 1988. The day was inaugurated by Yasser Arafat in 1998.
The event is often marked by speeches and rallies by Palestinians in Israel, the West Bank and Gaza, in Palestinian refugee camps in Arab states, and in other places around the world. Protests at times develop into clashes between Palestinians and the Israel Defense Forces in the West Bank and Gaza Strip. In 2003 and 2004, there were demonstrations in London and New York City. In 2002, Zochrot was established to organize events raising the awareness of the Nakba in Hebrew so as to bring Palestinians and Israelis closer to a true reconciliation. The name is the Hebrew feminine plural form of "remember".
On Nakba Day 2011, Palestinians and other Arabs from the West Bank, Gaza Strip, Lebanon and Syria marched towards their respective borders, or ceasefire lines and checkpoints in Israeli-occupied territories, to mark the event. At least twelve Palestinians and supporters were killed and hundreds wounded as a result of shootings by the Israeli Army. The Israeli army opened fire after thousands of Syrian protesters tried to forcibly enter the Israeli-occupied Golan Heights resulting in what AFP described as one of the worst incidents of violence there since the 1974 truce accord.
The IDF said troops "fired selectively" towards "hundreds of Syrian rioters" injuring an unspecified number in response to them crossing onto the Israeli side.
According to the BBC, the 2011 Nakba Day demonstrations were given impetus by the Arab Spring. During the 2012 commemoration, thousands of Palestinian demonstrators protested in cities and towns across the West Bank and Gaza Strip. Protesters threw stones at Israeli soldiers guarding checkpoints in East Jerusalem who then fired rubber bullets and tear gas in response.
