Education and academic positions

Clark was educated at Sydney Grammar School from 1972 to 1978, the University of Sydney (where he studied history) and the Freie Universität Berlin from 1985 to 1987.{{cite magazine|url=https://www.society.caths.cam.ac.uk/Public_Magazines/1992r.pdf|title=The Governing Body's Invitation Dinner|page=18|magazine=St Catharine's College Society Magazine|date=September 1992|access-date=5 July 2023|archive-date=5 July 2023|archive-url=https://web.archive.org/web/20230705074805/https://www.society.caths.cam.ac.uk/Public_Magazines/1992r.pdf|url-status=dead}}

Clark received his PhD at the University of Cambridge, having been a member of Pembroke College from 1987 to 1991. He is Professor in Modern European History at the University of Cambridge and, since 1991, has been a fellow of St Catharine's College,{{citation

In 2003, Clark was appointed lecturer in Modern European History and, in 2006, reader in Modern European History. His Cambridge University professorship in history followed in 2008.{{cite web |url=https://www.hist.cam.ac.uk/people/professor-chris-clark|access-date=5 July 2023|title=Professor Christopher Clark, Regius Professor of History|publisher=Cambridge University}}

In September 2014 he succeeded Richard J. Evans as Regius Professor of History at Cambridge. In the birthday honours of June 2015, Clark was knighted on the recommendation of the foreign secretary for his services to Anglo-German relations.

Professional career

As he acknowledges in the foreword to Iron Kingdom,{{sfn|Clark|2006|pages=iii, iv, xi}} living in West Berlin from 1985 to 1987, during what turned out to be the last years of the divided Germany, gave him an insight into German history and society.

=Earlier work=

Clark's academic focus started with the history of Prussia, with his earlier researches concentrating on Pietism and on Judaism in Prussia as well as the power struggle, known as the Kulturkampf, between Bismarck's Prussian state and the Catholic Church. His scope has since broadened to embrace more generally the competitive relationships between religious institutions and the state in modern Europe. He is the author of a study of Christian–Jewish relations in Prussia, The Politics of Conversion. Missionary Protestantism and the Jews in Prussia, 1728–1941.{{sfn|Clark|1995}}

=''Iron Kingdom: The Rise and Downfall of Prussia, 1600–1947''=

Clark's best-selling history of Prussia, Iron Kingdom: The Rise and Downfall of Prussia, 1600–1947{{sfn|Clark|2006}} won several prizes. Its critical reception gave him a public profile that reached beyond the academic world. The German-language version of the book, Preußen. Aufstieg und Niedergang 1600–1947, won Clark the 2010 {{ill|German Historians' Prize|de|Preis des Historischen Kollegs}}, an award normally given to historians nearing the end of their careers. Clark remains (in 2014) the youngest-ever recipient of the triennial prize and the only winner not to have approached his work as a mother-tongue German-speaker.

In 17 chapters covering 800 pages, Clark contends that Germany was "not the fulfillment of Prussia's destiny but its downfall"."Nicht die Erfüllung Preußens, sondern sein Verderben". Christopher Clark: Preußen. Aufstieg und Niedergang. 1600–1947. 2007, p. 13. Although the 19th-century Kulturkampf was characterised by a peculiar intensity and radicalism, Clark's careful study of sources in several different European languages enabled him to spell out just how closely the Prussian experience of church-state rivalry resembled events elsewhere in Europe. In that way, the book powerfully rebuts the traditional Sonderweg bandwagon by which throughout the 20th century, mainstream historians placed great emphasis on the "differentness" of Germany's historical path before and during the 19th century. Clark downplays the perceived uniqueness of the much-vaunted reform agenda, which was pursued by Prussia between 1815 and 1848, and believes that the political and economic significance of the German customs union, established in 1834, came to be discovered and then overstated by historians only retrospectively and in the light of much-later political developments.

=''Kaiser Wilhelm II''=

With his critical biography of the last German Kaiser, Kaiser Wilhelm II,{{sfn|Clark|2000}} Clark aims to offer correctives to many of the traditional positions presented in J. C. G. Röhl's three-volume biography of Wilhelm.

=''The Sleepwalkers: How Europe Went to War in 1914''=

Clark's study of the outbreak of the First World War, The Sleepwalkers: How Europe Went to War in 1914, appeared in English in 2012;{{cite web|url=http://www.deutschlandfunk.de/interview-mit-christopher-clark-dieser-krieg-hat-das-ganze.724.de.html?dram:article_id=275077|access-date=26 June 2014|title=Interview mit Christopher Clark. "Dieser Krieg hat das ganze Jahrhundert entstellt"|date=20 January 2014 |type=Deutschlandfunk interview in German, originally published in 2013, by Thilo Kößler with Clark about Clark's book The Sleepwalkers: How Europe Went to War in 1914}} the German version (Die Schlafwandler: Wie Europa in den Ersten Weltkrieg zog) followed in 2013. The book challenges the imputation, which had been widely accepted by mainstream scholars since 1919, of a peculiar "war guilt" attaching to the German Empire. He instead maps carefully the complex mechanism of events and misjudgements that led to war.{{cite news |author= Berthold Seewald|url=https://www.welt.de/geschichte/article121231599/Besessen-von-der-deutschen-Kriegsschuld.html|title=Besessen von der deutschen Kriegsschuld|quote=Mit seinen neuen Thesen zum Kriegsausbruch 1914 provoziert der britische Historiker Christopher Clark heftige Debatten.

Risks inherent in the strategies pursued by the various governments involved had been taken before without catastrophic consequences, which now enabled leaders to follow similar approaches without adequately evaluating or recognising those risks. Among international experts, many saw the presentation by Clark of his research and insights as groundbreaking.Richard J. Evans. Review of Christopher Clark, The Sleepwalkers. How Europe Went to War in 1914 (London 2013). The New York Review of Books, 6 February 2014, pp. 14–17.

In Germany itself, where the book received much critical attention, not all reactions were positive. Volker Ullrich contended that Clark's analysis largely disregards the pressure for war coming from Germany's powerful military establishment.Volker Ullrich.

According to Hans-Ulrich Wehler, Clark had diligently researched the sources covering the war's causes from the German side only to "eliminate [many of them] with bewildering one-sidedness". Wehler attributed the sales success of the book in Germany to a "deep-seated need [on the part of German readers], no longer so constrained by the taboos characteristic of the later twentieth century, to free themselves from the burdensome allegations of national war guilt".Hans-Ulrich Wehler. "Beginn einer neuen Epoche der Weltkriegsgeschichte", Frankfurter Allgemeine Zeitung, 6 May 2014, no. 104, p. 10 {{in lang|de}} However, Clark observes that the current German debate about the start of the war is obfuscated by its link to their moral repugnance at the Nazi era.{{sfn|Clark|2012|pp=560–561}}

In 2010, Clark was elected a member of the British Academy.

=Controversy and criticism=

File:Christopher Clark.jpg

In 2019, Clark was embroiled in controversy surrounding his 2011 report, commissioned by the head of the Hohenzollern family, Georg Friedrich, Prince of Prussia, on the Hohenzollern family's relations with the Nazis. The report was in support of the family's claims for compensation under a 1994 German law allowing restitution for the loss of property confiscated by the German Democratic Republic if the claimants or their ancestors had not "given substantial support" to the National Socialist or the East German Communist regimes. Clark acknowledged that expressions of support for the Nazis had been made by the last Kaiser's eldest son, Wilhelm, the most senior member of the former dynasty in Germany in the 1920s and the 1930s and the owner of the Hohenzollern properties. However, his report concluded that Wilhelm was "one of the politically most reserved and least compromised persons" of the aristocratic Nazi collaborators and that he was simply too marginal a figure to have been able to give "significant support" to Hitler, a position that supported the Hohenzollerns' claims.[https://www.nybooks.com/articles/2020/03/26/what-do-the-hohenzollerns-deserve/ "What Do the Hohenzollerns Deserve?"] by David Motadel, The New York Review of Books, 26 March 2020 {{subscription required}}

Clark's report was criticised by two historians commissioned by the German state to consider the Hohenzollern claims: {{ill|Peter Brandt (historian)|de|Peter Brandt (Historiker)|lt=Peter Brandt}}, a specialist in Prussia and imperial Germany at the University of Hagen, and {{ill|Stephan Malinowski|de}}, a German historian at the University of Edinburgh who is the author of the standard work on the relationship between the German aristocracy and the Nazi movement, Vom König zum Führer (2003). Brandt and Malinowski provided substantial further evidence of Wilhelm's support for the Nazis that Clark had overlooked. Their two reports leave no doubt about the prince's deep-seated anti-Semitism. During the historical controversy that unfolded in the German press, Richard J. Evans, Clark's predecessor as Regius Professor of History (Cambridge), criticised his colleague for not reflecting more carefully before accepting offers to produce expert reports. In 2020, however, Clark claimed to have changed his view and more or less agreed with Malinowski.{{Cite news | url=https://taz.de/Preussen-Historiker-Clark-rudert-zurueck/!5734272/ | title=Preußen-Historiker Clark rudert zurück: Kampf um das Tafelsilber | newspaper=Die Tageszeitung: Taz| date=12 December 2020 | last1=Fanizadeh | first1=Andreas }}
