Mazower was born in Golders Green and spent most of his early life in north London. His mother was a physiotherapist and his father worked for Unilever. During his youth, Mazower enjoyed playing the French horn and composing classical music. Mazower's father was of Russian Jewish descent. When Mazower began to write his book What You Did Not Tell: A Russian Past and the Journey Home, he discovered that his grandfather, Max, was a member of the Bund, a Jewish socialist party, was involved in revolutionary activities, and helped print illegal books in Yiddish advocating socialism. Max was regularly arrested by the Tsarist police and was imprisoned twice in Siberia, before eventually fleeing the country and settling in England in 1924. Mazower also discovered that his grandparents continued to hang out with Russian-Jewish revolutionaries in Golders Green. Reflecting on the discovery, Mazower said: During his youth, Mazower enjoyed reading classical literature and philosophy.
Mazower has written extensively on Greek and Balkan history. His book The Balkans won the Wolfson History Prize and Inside Hitler's Greece: The Experience of Occupation, 1941–44, both won the Longman History Today Award for Book of the Year. Salonica, City of Ghosts: Christians, Muslims and Jews 1430–1950 was the Runciman Prize and Duff Cooper Prize winner and was shortlisted for the Hessell-Tiltman Prize. In addition, Mazower is more broadly concerned with 20th-century European history. His book argued that the triumph of democracy in Europe was not inevitable but rather the result of chance and political agency on the part of citizens, subjects and leaders. In Hitler's Empire: Nazi Rule in Occupied Europe, Mazower compared Nazi German occupation policy in different European countries. Mazower's book, No Enchanted Palace, was published in 2009. It narrates the origins of the United Nations and its strict ties to colonialism and its predecessor organisation, the League of Nations. In Governing the World, this narrative is taken one step further, and the history of international organisations in general is evaluated, beginning with the Concert of Europe at the start of the nineteenth century. Mazower's 2018 inter-generational biography of his own family, What you did not tell, described their lives, education and politics and how it influences his interest in history, place, and the writing of biography.Caroline Moorehead, an acclaimed biographer, on reviewing this book, wrote of his scholarly reconstruction of a family's life meticulously drawn from archives and collections of papers in the UK, Russia, Belgium and Israel and family dairies, letters and interviews. Not simply a biographical narrative, Moorehead explains, since woven into it is a vast and rich picture of left wing European Jewry from the founding of the Bundworkers' union. HIs prodigious historical reach is matched by his affectionate portrait of a family and a people 'whose fight for justice was based on their own personal knowledge of poverty and exploitation.'
