In 1948, the land then known as Mandatory Palestine saw the end of British rule, the creation of the State of Israel, a regional Arab–Israeli war, and the mass displacement of Palestinians, events remembered very differently by Israelis and Palestinians.

Before 1948: Partition and rising tension

  • In November 1947, the UN voted for a partition plan to end British rule by creating two states, one Jewish and one Arab, with Jerusalem under international control.
  • Most Zionist leaders accepted the plan as a basis for a state, even if reluctantly, while Palestinian Arab leaders and surrounding Arab states rejected it as unfair and illegitimate.
  • From late 1947, violence escalated between Jewish and Arab communities: ambushes, riots, and reprisal attacks, turning the mandate into a civil war zone.

Key idea

The stage was set for a clash between two nationalist movements—Zionist Jewish and Palestinian Arab—each claiming the same land as their homeland.

1948: War of Independence and Nakba

On 14 May 1948, as Britain withdrew, Jewish leaders declared the establishment of the State of Israel in part of the territory.

  • The next day, armies from Egypt, Transjordan (Jordan), Syria, Lebanon, and Iraq entered the territory, joining local Palestinian Arab forces against the new state.
  • Israel calls this the War of Independence and sees it as a fight for survival against multiple Arab armies.
  • Palestinians call 1948 the Nakba (“Catastrophe”), marking the destruction of much of their society and loss of their homes and homeland.

The war had two main phases:

  1. Civil war phase (late 1947 – mid‑May 1948)
    • Jewish and Arab militias fought over roads, cities, and villages while the British pulled back.
 * Jewish forces (mainly the Haganah, plus Irgun and Lehi) launched operations to secure areas assigned to the Jewish state and main supply routes, especially to Jerusalem.

 * Notorious incidents included the April 1948 attack on the village of Deir Yassin by Irgun and Lehi, where around 100 villagers were killed, which spread fear widely.
  1. Inter‑state war (mid‑May 1948 – early 1949)
    • After independence, the conflict turned into a full Arab–Israeli war, with conventional battles between the new Israeli army and Arab state armies.
 * Israel gradually moved from defensive to offensive operations, capturing large areas beyond those allocated by the UN plan.

 * Armistice agreements in 1949 ended active fighting but not the conflict itself.

Borders and control after the war

By the end of the fighting, the map of the land had changed dramatically.

  • Israel controlled about 78% of the former British Mandate territory, more than the UN partition plan had assigned.
  • Jordan occupied and later annexed the West Bank and East Jerusalem.
  • Egypt controlled the Gaza Strip.
  • The ceasefire lines drawn in 1949 became known as the “Green Line.”

These lines—not recognized as final borders—became the starting point for later negotiations and conflicts.

Refugees and the human impact

One of the most lasting consequences of 1948 was the large-scale displacement of Palestinians.

  • Over 700,000 Palestinian Arabs fled or were forced from their homes in what became Israel, ending up in the West Bank, Gaza, and neighboring countries.
  • Hundreds of Palestinian villages were depopulated or destroyed, and many Palestinians were not allowed to return.
  • Palestinians remember this as the Nakba, commemorated annually as a day of mourning and reflection.

At the same time:

  • Hundreds of thousands of Jews arrived in Israel in the years around 1948, including Holocaust survivors from Europe and Jews who left or were expelled from Arab countries.

Different narratives about why people left

Historians and communities disagree on the main causes of the Palestinian exodus.

  • Some point to direct expulsions and intimidation by Jewish/Israeli forces in certain areas.
  • Others emphasize fear, chaos, and calls by some Arab leaders to leave temporarily during the fighting, expecting a quick victory and return.
  • Most modern scholarship sees the exodus as caused by a mix of military operations, fear of massacres, breakdown of order, and, in some cases, deliberate policies to prevent return.

Why 1948 still matters today

The events of 1948 are the starting point of both the Israeli–Palestinian conflict and the broader Arab–Israeli conflict.

  • For many Israelis, 1948 is a story of national rebirth and survival after statelessness and genocide.
  • For many Palestinians, it is the foundational trauma of dispossession, statelessness, and life as refugees or under occupation.
  • Core issues in today’s peace efforts—refugees, borders, Jerusalem, security, and recognition—are all rooted in how 1948 unfolded and how each side remembers it.

TL;DR:
In 1948, as Britain left Palestine and Jewish leaders declared Israel’s independence, war broke out between Jewish/Israeli forces, Palestinian Arabs, and neighboring Arab states. Israel survived and expanded its territory, while more than 700,000 Palestinians became refugees in what they call the Nakba, a catastrophe that still shapes the conflict today.
