Hugh Thomas

Hugh Swynnerton Thomas, Baron Thomas of Swynnerton (21 October 1931 – 7 May 2017) was a British historian whose work on Spain, the Spanish Empire, the Atlantic slave trade, and the conquest of the Americas made him one of the most productive and widely read historians of the postwar period. His debut, The Spanish Civil War (1961), remains the definitive English-language account of the conflict sixty years after its publication.

Early Career and The Spanish Civil War (1961)

Thomas was born in Windsor, educated at Sherborne School and Queens’ College, Cambridge, and entered the Foreign Office, where he served briefly before turning to historical writing. His decision to write a comprehensive account of the Spanish Civil War — a subject that had generated enormous passions but no adequate synthesis — was characteristically ambitious.

The Spanish Civil War was published when Thomas was twenty-nine and was immediately recognised as a masterpiece of historical narrative. The book’s achievement was to combine meticulous research in Spanish, British, and other archives with a clarity of exposition and a fairness of judgment that had eluded previous accounts, which had tended to be either Republican or Nationalist polemics.

Thomas navigated the political minefield with remarkable skill: he treated the Republic, the Nationalists, the anarchists, the communists, the International Brigades, and the foreign powers with equal seriousness and equal scrutiny. The book was praised across the political spectrum and has been regularly revised and expanded (the most recent edition runs to over a thousand pages).

The Spanish Empire Trilogy

Thomas’s most ambitious project was his trilogy on the Spanish Empire in the Americas:

The Conquest of New Spain — published as Conquest: Montezuma, Cortés, and the Fall of Old Mexico (1993) — is a vivid, detailed account of Hernán Cortés’s campaign against the Aztec Empire, drawing on both Spanish and indigenous sources to reconstruct one of the most dramatic episodes in world history. The book is notable for its evenhanded treatment of both Cortés and Moctezuma, and for its willingness to present the conquest as a genuine clash of civilisations rather than a simple story of European aggression.

Rivers of Gold: The Rise of the Spanish Empire (2003) covers the period from Columbus’s first voyage to the death of Ferdinand of Aragon, tracing the early Spanish colonisation of the Caribbean and Central America.

The Golden Age: The Spanish Empire of Charles V (2010) continues the story through the reign of Charles V, covering the consolidation of Spanish power in the Americas and the exploration of the Pacific.

The Slave Trade (1997)

Thomas’s history of the Atlantic slave trade — subtitled The Story of the Atlantic Slave Trade, 1440–1870 — is a comprehensive, narrative account of one of the largest forced migrations in human history. The book covers the origins of the trade in Portuguese West Africa, its expansion under Spanish, Dutch, British, and French auspices, the Middle Passage, the plantation economies of the Americas, and the abolitionist movement.

The book was praised for its scope, its narrative energy, and its willingness to assign responsibility to African, Arab, and European participants alike. It won the £30,000 Alan Coren Prize for wit and was shortlisted for other awards.

Cuba and Other Works

Thomas’s Cuba, or the Pursuit of Freedom (1971) is a massive history of Cuba from the eighteenth century to the aftermath of the Castro revolution — a book that was controversial on the left (Thomas was perceived as too critical of Castro) and admired on the right (Margaret Thatcher was an admirer and later ennobled Thomas as Baron Thomas of Swynnerton).

His other works include The Suez Affair (1967), one of the first serious accounts of the 1956 crisis; An Unfinished History of the World (1979, revised as A History of the World, 1996); and Armed Truce: The Beginnings of the Cold War, 1945–46 (1986).

Critical Standing

Thomas was a historian of the narrative tradition — closer in method to Gibbon and Macaulay than to the Annales school or the social historians who dominated the academy. His books are long, detailed, based on primary sources, and written with the expectation that history should be readable. Academic historians sometimes criticised his work as insufficiently analytical, but his command of sources and his ability to synthesise enormous amounts of material into coherent, compelling narratives were widely admired.

His political journey — from Labour-sympathising young man to Thatcherite peer — mirrors a broader trajectory in postwar British intellectual life and coloured the reception of his work. The Spanish Civil War book’s fairness was praised precisely because Thomas’s sympathies were hard to pin down; by the time he was writing Cuba, the conservative leanings were more visible, and left-leaning critics accused him of Cold War bias. The charge is not entirely fair: Thomas was genuinely interested in the complexity of revolutionary movements, and Cuba remains indispensable even for scholars who disagree with its conclusions. His greatest strength — and the reason his best books will endure — was his ability to manage enormous casts of characters and intricate chronologies without losing narrative momentum or the reader’s interest.
