Roger Moorhouse

Moorhouse is a regular public speaker, and has appeared, among others, at the Edinburgh International Book Festival and the Bath Literature Festival. Since 2016, he has been a visiting professor at the College of Europe in Natolin near Warsaw. He is a Fellow of the Royal Historical Society.

In 2014, his The Devils' Alliance: Hitler's Pact with Stalin, 1939-1941 was published. Whilst praising the book for its "masterly" account of the signing of the Molotov–Ribbentrop Pact, historian Richard J. Evans took exception to the book's "unbalanced treatment" of the crimes of the Soviets over those of the Nazis, asserting that "for all its virtues this is a deeply problematic book". Other reviewers of the book were more positive – the Wall Street Journal described it as "superb" and The Daily Telegraph listed it among its Books of the Year for 2014.

In 2006, Moorhouse's first solo book, Killing Hitler, was published, which has since been translated a number of times. In a CNN news report of 3 September 2011, Killing Hitler was shown on Al-Saadi Gaddafi's desk after he had fled his office in the wake of the collapse of the Gaddafi regime in Libya. Reporter Nic Robertson suggested that Saadi Gaddafi had been reading the book prior to his flight.

His next book, Berlin at War, is a social history of Berlin during World War II, which was published in the summer of 2010. Writing in the Financial Times, Andrew Roberts commented that: "Few books on the war genuinely increase the sum of our collective knowledge of this exhaustively covered period, but this one does". "Berlin at War" was listed amongst the books of the year for 2010 by The Daily Telegraph, and American Spectator magazine, among others, and was shortlisted for the Hessell-Tiltman Prize for history.

Whilst a student, Moorhouse worked as a researcher for Professor Norman Davies, collaborating on many of the latter's best-known publications, including Europe: A History, The Isles: A History and Rising '44 and culminating in the publication in 2002 of a co-authored study of the history of the city of Wrocław (the former German Breslau) entitled Microcosm: Portrait of a Central European City.

He attended Berkhamsted School and the School of Slavonic and East European Studies of the University of London, graduating with an MA in history and politics in 1994.

Roger Moorhouse (born 1968 in Stockport, Cheshire) is a British historian and author.

Moorhouse's most recent publication, First to Fight: The Polish War 1939 (2019 in the UK, 2020 in the US), on the German and Soviet invasion of Poland in September 1939, was widely acclaimed ("fascinating" according to The Telegraph, "deeply researched, very well written . . . standard work" in the words of Andrew Roberts, "timely and authoritative" according to The Spectator), named among books of the year for 2019 by BBC History Magazine and The Daily Telegraph, and shortlisted for the Duke of Wellington Medal for Military History 2020.
