Since 1948, and again in 1967, millions of Palestinians have been driven from their homes and live in squalor in refugee camps which festoon the Arab world.

But the roots of the conflict pre-date the UN mandate which led to the creation of Israel in 1948.

Arthur James Balfour, Britain’s foreign secretary, sends a letter to Lord Rothschild, president of the Zionist federation, stating the government’s support for the establishment of “a national home for the Jewish people” in Palestine, the area consisting of today’s Israel, the West Bank, Gaza Strip and Jordan.

The declaration reads: “His Majesty’s Government view with favour the establishment in Palestine of a national home for the Jewish people, and will use their best endeavours to facilitate the achievement of this object, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country.”
