Harold Nicolson’s career brought him into contact with diplomacy at close quarters: he worked in the Foreign Office during the First World War, served at the Paris Peace Conference and later wrote about both diplomacy and the people who practised it. He was also a Member of Parliament, broadcaster and diarist. His life ranged from the diplomatic service to the House of Commons and Sissinghurst, where he and Vita Sackville-West made a garden that remains part of England’s cultural landscape.

A diplomatic childhood and career

Harold George Nicolson was born in Tehran on 21 November 1886, the youngest son of diplomat Arthur Nicolson, later 1st Baron Carnock. His childhood took him to several places where his father was posted, including St Petersburg, Constantinople, Madrid, Sofia and Tangier. He attended The Grange School in Folkestone and Wellington College before studying at Balliol College, Oxford, where he graduated in 1909. That year he entered the Foreign Office after passing the competitive examinations for the Diplomatic Service and Civil Service.

Nicolson’s early postings were in Madrid and Constantinople. During the First World War he served in London at the Foreign Office, rising to Second Secretary. On 4 August 1914, as the most junior member of staff at that rank, he delivered Britain’s revised declaration of war to Prince Max von Lichnowsky, the German ambassador in London. It was a brief but consequential duty at the moment Britain entered the war.

In 1919 Nicolson served in a junior capacity at the Paris Peace Conference. His later book Peacemaking 1919 drew on his experience there, but his role should not be confused with responsibility for drafting the Treaty of Versailles. In 1920 he became private secretary to Sir Eric Drummond, the first Secretary-General of the League of Nations, before being recalled to the Foreign Office. This was a connection to the new organisation, not evidence that he was instrumental in establishing it.

His diplomatic career continued in Tehran, where he became chargé d’affaires in 1925, and Berlin, where he served in 1928. After a dispute over a dispatch, he was recalled from Tehran to London in 1927 and demoted. He resigned from the Diplomatic Service in September 1929. His diplomatic writing later included Diplomacy and The Evolution of Diplomacy, works that drew on a career spent inside the institutions and conventions they examined.

Politics before and during the war

After leaving the service, Nicolson edited the Evening Standard’s “Londoner’s Diary” column, a job he disliked, and then entered party politics. In 1931 he joined Oswald Mosley’s New Party, stood unsuccessfully for the Combined English Universities and edited the party newspaper, Action. He broke with Mosley after the formation of the British Union of Fascists in 1932.

Nicolson entered the Commons in 1935 as National Labour MP for Leicester West. In the years before the Second World War, he was among the MPs warning about fascism and supported efforts to strengthen British resolve and rearm. He opposed the Munich Agreement. In a Commons speech in October 1938, he defended what he called a “Foreign Office mind”: the belief that Britain should uphold standards of conduct in Europe rather than make agreements with governments whose actions he considered evil.

During Churchill’s wartime government, Nicolson served for about a year as Parliamentary Secretary and official Censor at the Ministry of Information. He also served on the BBC’s Board of Governors from 1941 to 1946. He lost his parliamentary seat in the 1945 general election. He joined the Labour Party in 1947 and stood unsuccessfully in the 1948 Croydon North by-election; he did not serve as a Labour MP after leaving the Commons.

His public positions could be uncomfortable. In 1944, while his son Nigel was serving with the Eighth Army in Italy, Nicolson opposed bombing the abbey at Monte Cassino because of its artistic importance. He argued that the works of art could not be replaced, even at the cost of lives. The abbey was destroyed in an American bombing raid on 15 February 1944. The episode captures a difficult collision between cultural preservation and military necessity, rather than a simple consensus about what should be sacrificed.

Books, diaries and public life

Nicolson wrote across several genres. His early books included biographies and studies of literary figures such as Paul Verlaine, Tennyson, Byron and Swinburne. Peacemaking 1919, published in 1933, offered his account of the Paris conference; The Congress of Vienna, published in 1946, examined a different settlement and its political context. He also wrote Public Faces, a 1932 novel that imagined a future in which an atomic bomb formed part of British policy, and King George V, published in 1952.

His diaries and letters are a further part of his record of public life. Nicolson wrote about political figures and events from the position of someone who had worked in diplomacy, parliament and government. The diaries were published in volumes edited by his son Nigel, who also brought out his parents’ correspondence. These books preserve Nicolson’s observations, but a diary remains a personal record rather than a neutral account; his own views and prejudices are part of what readers encounter.

In 1930, Nicolson married Vita Sackville-West, the poet, novelist and garden designer. They had two sons, Benedict and Nigel. Their life together included long periods apart, during which they wrote to one another. In 1930 Sackville-West acquired Sissinghurst Castle in Kent. There, she and Nicolson created the gardens now cared for by the National Trust. Their work at Sissinghurst joined Nicolson’s public career to a lasting cultural project at home.

Honours and later years

Nicolson’s later roles included broadcasting and writing for periodicals, alongside his books and diaries. In 1953 he was appointed Knight Commander of the Royal Victorian Order for writing the official biography of George V, published the previous year. He died at Sissinghurst Castle on 1 May 1968, aged 81. A blue plaque commemorates him and Sackville-West at their former home in Ebury Street, London.

Why Harold Nicolson deserves a place in British Legacy

Nicolson’s place in British history rests on the range of his public work and the detail of the record he left behind. As a diplomat, he served during the First World War, took part in the Paris Peace Conference in a junior capacity and worked as private secretary to the first Secretary-General of the League of Nations. As an MP, he spoke against appeasement and warned about fascism before the Second World War. These experiences gave him material for books on diplomacy and political life, while his diaries offer a view of public events from inside the circles in which they unfolded. His career is a useful reminder that diplomatic influence should be described precisely: he had close contact with the League, but the evidence here does not make him its founder.

His legacy is not confined to government and writing. At Sissinghurst, Nicolson and Vita Sackville-West helped create a garden that continues to be cared for by the National Trust, bringing their shared work into a public setting. His books, diaries and correspondence also connect political history with literary biography and personal observation. Together, these strands explain his significance to British Legacy: Nicolson was not simply a diplomat who turned to politics, or a writer who recorded famous people. He moved between institutions, public debate and cultural life, leaving distinct contributions in each. Remembering those achievements together gives a fuller account than either diplomatic reputation or the story of Sissinghurst alone.
