Why We Are at War (2nd Edition, revised)

In Short

Written by members of the Oxford Faculty of Modern History during the opening months of World War I, this historical analysis examines the immediate and deep-seated causes of the European conflict. The authors detail diplomatic negotiations, treaty histories, and the strategic decisions that led Great Britain into war following the violation of Belgian neutrality. Combining narrative synthesis with official government documents, the work provides a contemporary record of how imperial rivalries and national doctrines collapsed European peace. It remains a crucial primary artifact, capturing the intellectual arguments and moral justifications framed by British scholars at the war's outbreak.

The Story

The argument opens by establishing the legal and historical framework of European diplomacy, focusing heavily on the guaranteed neutrality of Belgium and Luxemburg. The historians trace the formation of modern Belgium from the 1830s and examine the international treaties, particularly the Treaty of 1839, designed to protect smaller states from regional powers. They demonstrate that Britain's traditional foreign policy aimed at preventing any single empire from dominating the Low Countries, which served as a strategic buffer. Moving into the late nineteenth and early twentieth centuries, the narrative shows how European nations shifted away from isolation toward complex systems of alliances and local diplomatic understandings.

The narrative then addresses the immediate catalyst of the conflict: the July Crisis of 1914 following the assassination of Archduke Franz Ferdinand in Sarajevo. The authors chronicle the rapid escalation between Austria-Hungary and Serbia, explaining how Austrian demands were crafted to ensure rejection and provoke military action. As Russia moved to support Serbia, the dispute expanded into a general European confrontation. The text charts the desperate, unsuccessful attempts by British Foreign Secretary Sir Edward Grey to organize four-power mediation or secure diplomatic compromises through conversations in London, Berlin, and St. Petersburg.

Germany’s diplomatic strategy is highlighted as the central driver of the catastrophe. The authors scrutinize Imperial Chancellor Bethmann Hollweg's direct proposals to secure British neutrality, showing how Germany sought permission to crush France and bypass Belgian sovereignty while offering hollow promises regarding territorial integrity. When Britain refused these terms, maintaining that honor and treaty obligations required protecting European public law, German forces marched into Belgian territory. This act of aggression directly forced Great Britain to issue an ultimatum and declare war.

Beyond immediate diplomatic communications, the book explores the ideological motivations underpinning German aggression. The political philosophy of Heinrich von Treitschke is identified as a major force shaping German statecraft. According to this doctrine, the state represents supreme power above all international law, justifying conquest as a means of spreading national culture. The work concludes by reproducing extensive primary diplomatic documents, including the British White Book, the German White Book, and the Russian Orange Book, allowing readers to examine the evidence directly.

How It Unfolds

The foundation of neutrality The authors outline the nineteenth-century treaties securing Belgian and Luxemburg sovereignty, establishing that Britain's defensive policies rested on maintaining these international guarantees against aggressive neighboring empires.

The shift from isolation The narrative moves through early twentieth-century agreements, including Anglo-French and Anglo-Russian understandings, showing how Britain gradually abandoned isolation to preserve the balance of power without committing to offensive European alliances.

The July Crisis erupts Following the Sarajevo assassination, Austria-Hungary issues an ultimatum to Serbia, setting off a chain reaction of mobilizations while diplomatic efforts struggle to keep the local conflict from spreading across the continent.

The failed mediation Sir Edward Grey leads attempts to coordinate peace negotiations among the Great Powers, but persistent refusals and rigid military timelines frustrate every proposal for international arbitration.

The bid for neutrality Germany approaches Great Britain with proposals offering conditional promises regarding French territory in exchange for British neutrality, terms that the British government promptly rejects as a betrayal of its allies and public law.

The invasion and declaration German forces violate Belgian territory, prompting an immediate ultimatum from Great Britain, the breakdown of peace, and the formal entry of the British Empire into the war.

The primary record The book concludes with full texts and excerpts of diplomatic cables, government publications, and official notes from British, German, and Russian sources detailing the final exchanges before hostilities.

The People

Sir Edward Grey The British Foreign Secretary seeks to preserve European peace through continuous diplomatic mediation. He wants to prevent a continental war while respecting international treaties, but finds his efforts thwarted by rigid mobilizations. He ends the crisis forced to guide Britain into war to defend public law.

Count Berchtold The Austro-Hungarian Foreign Minister pursues a firm military settlement with Serbia following the royal assassination. He resists early calls for mediation, determined to maintain Austria-Hungary's status as a Great Power, ultimately driving his empire into a multi-front conflict.

Sergei Sazonov The Russian Foreign Minister acts to protect Serbian sovereignty and maintain Russian influence in the Balkans. Threatened by Austrian aggression, he mobilizes forces to preserve the balance of power, accepting the grave responsibility of a wider war when German demands arrive.

Heinrich von Treitschke Though not an active diplomat in 1914, the late historian acts as the intellectual architect of German policy in the authors' analysis. His political philosophy exalts state power above international law, framing war as a moral duty to spread German culture.

In Its Own Voice

"We have written this book to set forth the causes of the present war, and the principles which we believe to be at stake."

This opening statement from the scholars sets the objective tone of the volume, framing their work as an impartial historical analysis based on primary evidence rather than political rhetoric.

"To care for its power is the highest moral duty of the state."

Quoting the influential historian Treitschke, the authors highlight the core ideological principle that they argue drove German foreign policy to abandon international treaties in favor of raw military force.

"The whole of Europe would be thankful to them."

This cable from Russian Foreign Minister Sazonov to Sir Edward Grey underscores the intense pressure placed on British diplomacy to assume direction of peace discussions during the final hours before general mobilization.

What It's Really About

The book addresses the fundamental conflict between international law and unrestrained state power. It argues that European stability depends on the sacredness of treaties and the protection of smaller, neutral nations against expansionist empires. The authors assert that Britain entered the war not out of aggressive colonial ambition, but to uphold public law and prevent a single power from dominating the continent. Underneath the diplomatic chronologies lies a critique of aggressive nationalism that rejects moral obligations in favor of military expediency. The text presents the war as a defense of civilization and international order against a doctrine that treats might as the sole measure of right.

Why Read It Today

Historians, political scientists, and readers interested in the origins of World War I will find this book an invaluable contemporary document. It offers a clear, immediate look at how British intellectuals processed and explained the outbreak of war during its first months. Reading it feels like sitting in an archive alongside scholars frantically analyzing freshly released state papers while world events unfold outside.

The prose is precise, formal, and authoritative, moving smoothly between dense legal history and urgent diplomatic narrative. The work does present challenges: it assumes a basic familiarity with European geography and nineteenth-century political history, while the inclusion of official cables in their original French or unedited German translations requires focused attention. Furthermore, as a work published in 1914, it reflects the immediate British perspective of the conflict without the benefit of later twentieth-century historical hindsight. Nevertheless, its rigorous reliance on official records and its articulate presentation of international law make it a compelling read that reveals how the ideals of public faith and treaty obligations were defended at the onset of global catastrophe.<ElicitationsGroup message="Explore related historical aspects of the text:">
