Start with Knud J. V. Jespersen's A history of Denmark, the standard modern survey in English by a Danish historian, organised thematically as much as chronologically and unusually clear on how repeated losses of territory produced the national self-image. It is 262 pages and it carries the whole arc.
Then read Palle Lauring's A history of the kingdom of Denmark for what Jespersen compresses. It is an older popular narrative, translated in 1960, dated in its judgements and much fuller on the medieval and early modern kings. Between them these two also have to carry the Viking Age, which no dedicated book on this path covers — read their early chapters properly rather than skipping ahead to the modern material.
The Baltic empire and the Protestant kingdom
This is Denmark as a great power: controlling the Sound and its tolls, holding Norway, Iceland and Schleswig-Holstein, running an aggressive Baltic policy. Janus Møller Jensen's Denmark and the Crusades, 1400-1650 shows that crusading did not stop at the Reformation but was reworked into Baltic expansion and royal legitimacy — the ideological machinery behind Danish power.
Paul Douglas Lockhart wrote the next two. Frederik II and the Protestant cause shows a king carefully avoiding the war his co-religionists wanted; Denmark in the Thirty Years' War, 1618-1648 shows his grandson Christian IV not avoiding it, and the collapse of Danish power in northern Germany that followed. Read them in that order — the second is the clearest case study on this path of how the empire was lost, and why absolutism arrives in 1660.
Losing the empire, inventing the nation
Denmark lost Norway in 1814 and Schleswig and Holstein to Prussia in 1864, and answered by turning inward: folk high schools, cooperative dairies, a Lutheran national culture. The book the path uses here is catalogued under the bare title Denmark, by W. Glyn Jones with Kirsten Gade, and it comes with a caveat. Its subject metadata carries an unmistakable travel-guide fingerprint — guidebooks, description and travel — so before you buy, check that the edition you are looking at is the political and cultural history the path wants rather than a companion volume for visitors.
Alastair Hannay's Kierkegaard places its subject inside Golden Age Copenhagen rather than in a philosophical vacuum, so it doubles as intellectual history of the city; read the biographical and contextual chapters if the philosophy is not what you came for. Carol Gold's Danish Cookbooks is the odd one out and earns its place: an academic social history using cookbooks from 1616 to 1901 to trace how domesticity and national identity were built together, and the only book here that gets at nineteenth-century everyday life.
Occupation, and October 1943
Denmark surrendered in four hours in April 1940 and was then governed under a negotiated policy of cooperation until 1943. In the weeks after that policy broke down, almost all of the country's roughly 7,500 Jews were ferried to Sweden. The rescue is real and remarkable. The four books here are ordered so the account gets more complicated rather than simpler.
David Lampe's Hitler's savage canary, first published in 1957, is the classic popular history of the resistance — rousing, uncritical about the cooperation years, and the version most readers have absorbed. Jorgen Haestrup's Secret Alliance is the archival corrective by the historian who did the underlying work, at far greater depth and much less romantically. One record note: our copy is listed at 1,162 pages, which is near-certainly a multi-volume work occupying a single catalogue slot, so check what you are actually buying.
Harold Flender's Rescue in Denmark was built on interviews with participants and survivors in 1963 while nearly all of them were alive, and is a collection of testimony as much as a history. Bo Lidegaard's Countrymen is the modern reassessment, arguing from contemporary documents that the rescue worked because Danish civil and political society had already refused to treat Jews as a separate category. That is the strongest version of the Danish exceptionalism case; historians who resist it point to the collaboration policy that preceded the rescue, to Denmark's restrictive refugee policy before the war, and to the German officials who leaked the roundup and then did not pursue it hard. Read Lidegaard last and test him against the other three.
The welfare state and its critics
Both closing books are written from outside the Danish consensus, which is the point. Kenneth E. Miller's Denmark, a troubled welfare state is an American political scientist examining the model at the point its costs became politically contested, and still the clearest institutional account in English. Michael Booth's The almost nearly perfect people punctures the Nordic-utopia genre from the inside; it covers all five Nordic countries, so read it for the Danish chapters and the argument they start.
