On November 2, 1917, British Foreign Secretary Arthur James Balfour signed a short letter addressed to Lionel Walter Rothschild, the 2nd Baron Rothschild and a leading figure of the British Jewish community. The letter was fewer than 200 words in total. Its central commitment occupied just 67 of them: “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.”
That single statement, known ever since as the Balfour Declaration, became one of the most consequential diplomatic documents of the twentieth century. It gave the formal backing of a great imperial power to the Zionist movement’s decades-long campaign for a Jewish homeland. It was incorporated into international law through the League of Nations Mandate system, became the guiding principle of British administration over Palestine for thirty years, and set in motion the chain of events that led to the founding of the State of Israel in 1948 and the Palestinian dispossession that accompanied it. The 67 words that Balfour signed on November 2, 1917, are still shaping the world today.
The Origins of Zionism: Theodor Herzl and the Campaign for a Jewish State
The Balfour Declaration was the product of more than two decades of organized Jewish nationalist campaigning that had built both a political program and a network of relationships with British politicians capable of delivering the declaration. Understanding that campaign is essential to understanding why the British government chose to make such a commitment in the middle of a world war.
The modern Zionist movement was founded by Theodor Herzl, an Austro-Hungarian Jewish journalist who had been radicalized by the Dreyfus Affair in France in 1894. The false conviction for treason of a Jewish French army officer, in a trial saturated with openly antisemitic sentiment, persuaded Herzl that Jewish assimilation into European societies was impossible and that the solution to centuries of pogroms, discrimination, and persecution lay in the creation of an independent Jewish state. He published The Jewish State in 1896, laying out his argument in theoretical and practical terms, and in 1897 convened the First Zionist Congress in Basel, Switzerland, which established the World Zionist Organization and formally adopted the goal of creating a legally secured, publicly recognized national home for the Jewish people in Palestine.
Palestine, then an Ottoman province, held deep historical and religious significance for Jews as the ancient homeland from which Jewish communities had been dispersed under Roman rule almost two thousand years earlier. Jewish immigration to Palestine had been increasing throughout the late nineteenth and early twentieth centuries, driven largely by brutal antisemitic pogroms in Russia and Eastern Europe. By 1914, approximately 60,000 Jews lived in Palestine, representing around eight percent of the total population, the vast majority of which was Arab Muslim and Christian. Zionist settlers had established agricultural communities, cultural institutions, and political organizations, but the goal of a nationally recognized homeland remained far from achieved.
Leo Pinsker, whose 1882 pamphlet Auto-Emancipation had argued for Jewish national self-determination before Herzl, and the broader intellectual tradition of Jewish nationalism provided the ideological foundation on which Herzl built. After Herzl’s death in 1904, the movement continued under new leadership, most importantly under Nahum Sokolow and, above all, Chaim Weizmann, who would prove to be the decisive figure in securing British support.
Chaim Weizmann: The Scientist and Diplomat Who Delivered the Declaration
Of all the individuals who shaped the Balfour Declaration, none was more important than Chaim Weizmann. Born in 1874 in Motol in the Russian Empire, Weizmann had emigrated to England in 1904 and become a chemistry lecturer at the University of Manchester. He was both a brilliant scientist and one of the most accomplished political operators of his generation, combining intellectual precision with personal charm and an extraordinary ability to present Zionist aims in terms that resonated with British political culture.
Weizmann’s scientific work gave him direct access to the wartime British government. He had developed an industrial fermentation process for producing acetone from starch, and acetone was a critical ingredient in the manufacture of cordite, the propellant used in British artillery shells. Before the war, Britain had imported much of its acetone from Germany. Weizmann’s process made him personally valuable to the war effort, and the relationships he built through that work opened doors in Downing Street, the Foreign Office, and the War Cabinet. He had known Arthur Balfour since 1906, cultivated relationships with David Lloyd George, Winston Churchill, and other leading figures of the British political elite.
He represented himself as the authentic voice of world Jewry and framed Zionist aspirations in terms that appealed simultaneously to British Biblical Protestant sentiment, imperial strategic interest, and wartime political calculation. On June 13, 1917, Ronald Graham, head of the Foreign Office’s Middle Eastern affairs department, confirmed that the three most relevant British politicians, Prime Minister Lloyd George, Foreign Secretary Balfour, and Parliamentary Under-Secretary Lord Robert Cecil, were all in favor of publicly supporting the Zionist movement. On June 19, 1917, at a meeting in the Foreign Office, Balfour asked Lord Rothschild and Weizmann to submit a draft formula for a declaration. The formal drafting process had begun.
The British Politicians Behind the Declaration: Lloyd George, Balfour, Samuel, and Montagu
The Balfour Declaration was the product of advocacy both inside and outside the British government, and understanding the key individuals reveals why it took the particular form it did.
Arthur James Balfour was born in 1848 into the Scottish aristocracy, had served as Prime Minister from 1902 to 1905, and was appointed Foreign Secretary by Lloyd George in December 1916. Balfour combined genuine personal sympathy for Jewish restoration, rooted partly in his Protestant Biblical upbringing, with an appreciation of the declaration’s propaganda value. He told the War Cabinet in October 1917 that “the sympathy of Jews throughout the world might be a most useful asset” for the Allied cause.
David Lloyd George, who became Prime Minister in December 1916, was a Welsh Baptist who had grown up steeped in the Old Testament and who later recalled that he and his colleagues “were brought up to believe that the return of the Jews to Palestine was one of the great prophecies and one of the great achievements to be realized.” Beyond Biblical sentiment, Lloyd George had a strategic vision: exclusive British control over Palestine would secure the land bridge between Egypt, the Suez Canal, and the route to India, undercutting the Sykes-Picot Agreement’s provision for international administration of the territory.
Herbert Samuel was a Jewish Liberal politician and the first Jewish Cabinet minister in British history. As early as February 1915, Samuel had circulated a memorandum to the Cabinet proposing British support for Zionist ambitions as a means of enlisting Jewish support for the Allied war effort. He would later become Palestine’s first High Commissioner in August 1920. Lord Alfred Milner, one of the five original members of Lloyd George’s War Cabinet, played an important role in drafting the declaration’s final language, introducing the critical shift from all of Palestine to a national home established “in Palestine,” significantly narrowing the geographic scope of the commitment.
The most significant opponent within the government was Edwin Montagu, the Secretary of State for India and the only Jewish member of the Cabinet in 1917. Montagu was an assimilationist Jew who viewed Zionism as a direct threat to Jews who had fully integrated into British society. In August 1917 he submitted a memorandum titled “The Anti-Semitism of the British Government,” arguing that declaring Palestine the national home of the Jewish people would mark all Jews everywhere as foreigners in their own countries and invite persecution. Montagu’s fierce opposition was ultimately overruled but was partly responsible for the inclusion of the safeguard clause protecting “the rights and political status enjoyed by Jews in any other country.”
The Drafting Process: From First Proposals to the Final 67 Words
The text of the Balfour Declaration went through multiple drafts between June and November 1917, each revision reflecting the competing pressures of Zionist advocates, anti-Zionist Jewish voices, and Cabinet members with different priorities.
The first formal Zionist draft, submitted by Lord Rothschild to Balfour on July 12, 1917, was a 143-word document calling for the reconstitution of Palestine as “the National Home of the Jewish people” and proposing substantial political powers for a Jewish National Colonizing Corporation. British officials including Sir Mark Sykes considered it too specific and politically sensitive. A subsequent much-shortened 46-word draft was submitted by Rothschild on July 18 and brought before the Cabinet for formal consideration.
The War Cabinet discussed the declaration at four meetings over the following two months, including the decisive meeting on October 31, 1917. Cabinet Secretary Maurice Hankey’s team solicited outside perspectives including the views of President Woodrow Wilson of the United States, whose position was described by Balfour in Cabinet minutes as “extremely favourable to the movement.” France had already expressed sympathy through a May 1917 letter from French diplomat Jules Cambon to Nahum Sokolow, supporting “Jewish colonisation in Palestine.”
Leo Amery, a Conservative MP and pro-Zionist member of the War Cabinet Secretariat, later claimed authorship alongside William Ormsby-Gore of the final wording. The text was agreed at the October 31 Cabinet meeting, the same day the Battle of Beersheba opened Britain’s military offensive into Palestine. Balfour signed and dispatched the letter on November 2, 1917. It was published in British and international newspapers on November 9. One week later, Vladimir Lenin and the Bolsheviks seized power in Russia and called for an immediate armistice, collapsing the Eastern Front regardless of any effect the declaration might have had on Russian Jewish opinion.

Three Conflicting Promises: The Arabs, Sykes-Picot, and the Contradictions of British Wartime Policy
The Balfour Declaration was not issued in diplomatic isolation. It was one of at least three conflicting commitments Britain had made regarding the future of Palestine and the wider Arab world, and those contradictions would haunt British policy for thirty years.
In 1915 and 1916, British High Commissioner in Egypt Sir Henry McMahon had conducted a correspondence with Sharif Hussein of Mecca, leader of the Arab nationalist movement, promising that Britain would support Arab independence in the Arab provinces of the Ottoman Empire in exchange for an Arab revolt against Ottoman rule. Prince Faisal, Hussein’s son, led Arab forces in revolt from June 1916, fighting alongside British forces including T.E. Lawrence. The Arabs fighting under this arrangement had reasonable grounds to believe that Palestine, as part of the Arab world they were helping to liberate, would form part of an independent Arab state.
In May 1916, the secret Sykes-Picot Agreement between Britain and France had divided the post-war Middle East into British and French spheres of influence and proposed international administration for Palestine specifically. The Bolsheviks published this secret agreement in November 1917, exposing Britain’s contradictory commitments to the world simultaneously with the Balfour Declaration’s publication.
The Arab majority of Palestine, approximately 90 percent of the total population, were not named in the Balfour Declaration. They appeared only in the safeguard clause as “existing non-Jewish communities in Palestine,” with their civil and religious but not political rights acknowledged. Ronald Storrs, Britain’s Military Governor of Jerusalem from 1917 to 1920, later observed that the Arab population was “not so much named but lumped together under the negative and humiliating definition of non-Jewish communities.” Balfour himself stated in February 1919 that Palestine was considered an exceptional case in which Britain “deliberately and rightly” declined to apply the principle of self-determination to the local population.
The British Mandate, the Mandate Years, and the Road to Israeli Statehood
Events moved rapidly after the declaration was issued. British troops under General Edmund Allenby entered Jerusalem on December 11, 1917, just six weeks after the letter was signed. By October 1918, Britain had occupied all of Palestine and imposed military government. Sir Herbert Samuel became Palestine’s first High Commissioner in August 1920, and the first immigration ordinance opening Palestine to Jewish immigration was passed that same month.
The declaration was formally incorporated into international law through the British Mandate for Palestine, approved by the Council of the League of Nations on July 24, 1922. The Mandate’s preamble referenced the Balfour Declaration and added a justification not in the original letter, namely the recognition of “the historical connection of the Jewish people with Palestine.” The Arab majority, roughly 90 percent of the population according to the 1922 British census, were again referenced only as “the non-Jewish communities” with no mention of political rights.
The subsequent thirty years of British Mandatory rule were marked by rising violence between the Jewish and Arab communities and by Britain’s growing inability to honor its contradictory commitments. Jewish immigration increased dramatically through the 1920s and 1930s, driven by the rise of Nazism in Europe and the desperate need of European Jews for refuge. Arab resistance expressed itself in violent confrontations, most significantly the Arab Revolt of 1936 to 1939, which Britain suppressed while commissioning successive inquiries into Palestine’s future.
In May 1939, Britain issued the MacDonald White Paper, effectively reversing the Balfour Declaration by restricting Jewish immigration to 75,000 over five years and envisioning an independent Palestine with Arab majority rule within ten years. Zionist leaders condemned this as betrayal. The Holocaust then killed six million Jews, transforming the moral landscape of the entire question and generating international support for Jewish statehood that could not be resisted.
The full consequences of the Balfour Declaration through the Mandatory period, the Holocaust, and the establishment of Israel in 1948 are documented in the Britannica article on the Balfour Declaration, which covers both the declaration’s immediate impact and the long arc of its consequences through the twentieth century.
Unable to manage the violence in Palestine, Britain handed the question to the United Nations in February 1947. The UN proposed a partition plan in November 1947. The Jewish leadership accepted it and Arab governments rejected it. On May 14, 1948, Britain’s Mandate ended and David Ben-Gurion declared the establishment of the State of Israel. The war that followed resulted in approximately 750,000 Palestinian Arabs fleeing or being expelled from their homes, the event Palestinians call the Nakba, meaning catastrophe. The Jewish communities around the world who had celebrated the Balfour Declaration when it was published in November 1917 celebrated the declaration of Israeli statehood in 1948 as the fulfillment of its promise. The Palestinians who had not been consulted in 1917 and whose political rights had not been mentioned in its text continued to experience the consequences of those omissions.
The History.com article on the Balfour Declaration traces the full path from Balfour’s letter to the founding of Israel and the beginning of the Israeli-Palestinian conflict that still defines one of the world’s most intractable disputes.
Balfour himself and Lloyd George reportedly told Chaim Weizmann in a 1922 meeting that the declaration “always meant an eventual Jewish state.” Whether that was always the intention or a retrospective reading of ambiguous language, the 67 words signed on November 2, 1917, ultimately produced a state, displaced a people, and set in motion a conflict whose resolution has not yet been found more than a century later.
