... "Strange, friend," I said, "Here is no cause to mourn."
"None," said the other, "Save the undone years"... 

— Wilfred Owen, Strange Meeting, 1918[241]

The first tentative efforts to comprehend the meaning and consequences of modern warfare began during the initial phases of the war, and this process continued throughout and after the end of hostilities, and still is underway, more than a century later.

Historiography

Historian Heather Jones argues that the historiography has been reinvigorated by the cultural turn in recent years. Scholars have raised entirely new questions regarding military occupation, radicalizion of politics, race, and the male body. Furthermore, new research has revised our understanding of five major topics that historians have long debated. These are: Why did the war begin? Why did the Allies win? Were the generals to blame for the high casualty rates? How did the soldiers endure the horrors of trench warfare? To what extent did the civilian homefront accept and endorse the war effort?[316]

Memorials

Memorials were erected in thousands of villages and towns. Close to battlefields, those buried in improvised burial grounds were gradually moved to formal graveyards under the care of organisations such as the Commonwealth War Graves Commission, the American Battle Monuments Commission, the German War Graves Commission, and Le Souvenir français. Many of these graveyards also have central monuments to the missing or unidentified dead, such as the Menin Gate memorial and the Thiepval Memorial to the Missing of the Somme.

In 1915 John McCrae, a Canadian army doctor, wrote the poem In Flanders Fields as a salute to those who perished in the Great War. Published in Punch on 8 December 1915, it is still recited today, especially on Remembrance Day and Memorial Day.[317][318]

National World War I Museum and Memorial in Kansas City, Missouri, is a memorial dedicated to all Americans who served in World War I. The Liberty Memorial was dedicated on 1 November 1921, when the supreme Allied commanders spoke to a crowd of more than 100,000 people.[319]

The UK Government has budgeted substantial resources to the commemoration of the war during the period 2014 to 2018. The lead body is the Imperial War Museum.[320] On 3 August 2014, French President Francois Hollande and German President Joachim Gauck together marked the centenary of Germanys declaration of war on France by laying the first stone of a memorial in Vieil Armand, known in German as Hartmannswillerkopf, for French and German soldiers killed in the war.[321]

Cultural memory

World War I had a lasting impact on social memory. It was seen by many in Britain as signalling the end of an era of stability stretching back to the Victorian period, and across Europe many regarded it as a watershed.[322] Historian Samuel Hynes explained:

A generation of innocent young men, their heads full of high abstractions like Honour, Glory and England, went off to war to make the world safe for democracy. They were slaughtered in stupid battles planned by stupid generals. Those who survived were shocked, disillusioned and embittered by their war experiences, and saw that their real enemies were not the Germans, but the old men at home who had lied to them. They rejected the values of the society that had sent them to war, and in doing so separated their own generation from the past and from their cultural inheritance.[323]

This has become the most common perception of World War I, perpetuated by the art, cinema, poems, and stories published subsequently. Films such as All Quiet on the Western Front, Paths of Glory and King & Country have perpetuated the idea, while war-time films including Camrades, Poppies of Flanders, and Shoulder Arms indicate that the most contemporary views of the war were overall far more positive.[324] Likewise, the art of Paul Nash, John Nash, Christopher Nevinson, and Henry Tonks in Britain painted a negative view of the conflict in keeping with the growing perception, while popular war-time artists such as Muirhead Bone painted more serene and pleasant interpretations subsequently rejected as inaccurate.[323] Several historians like John Terraine, Niall Ferguson and Gary Sheffield have challenged these interpretations as partial and polemical views:

These beliefs did not become widely shared because they offered the only accurate interpretation of wartime events. In every respect, the war was much more complicated than they suggest. In recent years, historians have argued persuasively against almost every popular cliché of World War I. It has been pointed out that, although the losses were devastating, their greatest impact was socially and geographically limited. The many emotions other than horror experienced by soldiers in and out of the front line, including comradeship, boredom, and even enjoyment, have been recognised. The war is not now seen as a fight about nothing, but as a war of ideals, a struggle between aggressive militarism and more or less liberal democracy. It has been acknowledged that British generals were often capable men facing difficult challenges, and that it was under their command that the British army played a major part in the defeat of the Germans in 1918: a great forgotten victory.[324]

Though these views have been discounted as "myths",[323][325] they are common. They have dynamically changed according to contemporary influences, reflecting in the 1950s perceptions of the war as "aimless" following the contrasting Second World War and emphasising conflict within the ranks during times of class conflict in the 1960s. The majority of additions to the contrary are often rejected.[324]

Social trauma

The social trauma caused by unprecedented rates of casualties manifested itself in different ways, which have been the subject of subsequent historical debate.[326]

The optimism of la belle époque was destroyed, and those who had fought in the war were referred to as the Lost Generation.[327] For years afterwards, people mourned the dead, the missing, and the many disabled.[328] Many soldiers returned with severe trauma, suffering from shell shock (also called neurasthenia, a condition related to posttraumatic stress disorder).[329] Many more returned home with few after-effects; however, their silence about the war contributed to the conflicts growing mythological status. Though many participants did not share in the experiences of combat or spend any significant time at the front, or had positive memories of their service, the images of suffering and trauma became the widely shared perception. Such historians as Dan Todman, Paul Fussell, and Samuel Heyns have all published works since the 1990s arguing that these common perceptions of the war are factually incorrect.[326]

Discontent in Germany

The rise of Nazism and Fascism included a revival of the nationalist spirit and a rejection of many post-war changes. Similarly, the popularity of the stab-in-the-back legend (German: Dolchstoßlegende) was a testament to the psychological state of defeated Germany and was a rejection of responsibility for the conflict. This conspiracy theory of betrayal became common, and the German populace came to see themselves as victims. The widespread acceptance of the "stab-in-the-back" theory delegitimized the Weimar government and destabilized the system, opening it to extremes of right and left.

Communist and fascist movements around Europe drew strength from this theory and enjoyed a new level of popularity. These feelings were most pronounced in areas directly or harshly affected by the war. Adolf Hitler was able to gain popularity by utilising German discontent with the still controversial Treaty of Versailles.[330] World War II was in part a continuation of the power struggle never fully resolved by World War I. Furthermore, it was common for Germans in the 1930s to justify acts of aggression due to perceived injustices imposed by the victors of World War I.[331][332][333] American historian William Rubinstein wrote that:

The Age of Totalitarianism included nearly all of the infamous examples of genocide in modern history, headed by the Jewish Holocaust, but also comprising the mass murders and purges of the Communist world, other mass killings carried out by Nazi Germany and its allies, and also the Armenian genocide of 1915. All these slaughters, it is argued here, had a common origin, the collapse of the elite structure and normal modes of government of much of central, eastern and southern Europe as a result of World War I, without which surely neither Communism nor Fascism would have existed except in the minds of unknown agitators and crackpots.[334]

Economic effects

One of the most dramatic effects of the war was the expansion of governmental powers and responsibilities in Britain, France, the United States, and the Dominions of the British Empire. To harness all the power of their societies, governments created new ministries and powers. New taxes were levied and laws enacted, all designed to bolster the war effort; many have lasted to this day. Similarly, the war strained the abilities of some formerly large and bureaucratised governments, such as in Austria-Hungary and Germany.

Gross domestic product (GDP) increased for three Allies (Britain, Italy, and US), but decreased in France and Russia, in neutral Netherlands, and in the three main Central Powers. The shrinkage in GDP in Austria, Russia, France, and the Ottoman Empire ranged between 30% to 40%. In Austria, for example, most pigs were slaughtered, so at wars end there was no meat.

In all nations, the governments share of GDP increased, surpassing 50% in both Germany and France and nearly reaching that level in Britain. To pay for purchases in the United States, Britain cashed in its extensive investments in American railroads and then began borrowing heavily on Wall Street. President Wilson was on the verge of cutting off the loans in late 1916, but allowed a great increase in US government lending to the Allies. After 1919, the US demanded repayment of these loans. The repayments were, in part, funded by German reparations which, in turn, were supported by American loans to Germany. This circular system collapsed in 1931 and the loans were never repaid. Britain still owed the United States $4.4 billion[335] of World War I debt in 1934, and this money was never repaid.[336]

Macro- and micro-economic consequences devolved from the war. Families were altered by the departure of many men. With the death or absence of the primary wage earner, women were forced into the workforce in unprecedented numbers. At the same time, industry needed to replace the lost labourers sent to war. This aided the struggle for voting rights for women.[337]

World War I further compounded the gender imbalance, adding to the phenomenon of surplus women. The deaths of nearly one million men during the war in Britain increased the gender gap by almost a million; from 670,000 to 1,700,000. The number of unmarried women seeking economic means grew dramatically. In addition, demobilisation and economic decline following the war caused high unemployment. The war increased female employment; however, the return of demobilised men displaced many from the workforce, as did the closure of many of the wartime factories.

In Britain, rationing was finally imposed in early 1918, limited to meat, sugar, and fats (butter and margarine), but not bread. The new system worked smoothly. From 1914 to 1918, trade union membership doubled, from a little over four million to a little over eight million.

Britain turned to her colonies for help in obtaining essential war materials whose supply had become difficult from traditional sources. Geologists such as Albert Ernest Kitson were called on to find new resources of precious minerals in the African colonies. Kitson discovered important new deposits of manganese, used in munitions production, in the Gold Coast.[338]

Article 231 of the Treaty of Versailles (the so-called "war guilt" clause) stated Germany accepted responsibility for "all the loss and damage to which the Allied and Associated Governments and their nationals have been subjected as a consequence of the war imposed upon them by the aggression of Germany and her allies."[339] It was worded as such to lay a legal basis for reparations, and a similar clause was inserted in the treaties with Austria and Hungary. However neither of them interpreted it as an admission of war guilt."[340] In 1921, the total reparation sum was placed at 132 billion gold marks. However, "Allied experts knew that Germany could not pay" this sum. The total sum was divided into three categories, with the third being "deliberately designed to be chimerical" and its "primary function was to mislead public opinion ... into believing the "total sum was being maintained."[341] Thus, 50 billion gold marks (12.5 billion dollars) "represented the actual Allied assessment of German capacity to pay" and "therefore ... represented the total German reparations" figure that had to be paid.[341]

This figure could be paid in cash or in kind (coal, timber, chemical dyes, etc.). In addition, some of the territory lost—via the treaty of Versailles—was credited towards the reparation figure as were other acts such as helping to restore the Library of Louvain.[342] By 1929, the Great Depression arrived, causing political chaos throughout the world.[343] In 1932 the payment of reparations was suspended by the international community, by which point Germany had only paid the equivalent of 20.598 billon gold marks in reparations.[344] With the rise of Adolf Hitler, all bonds and loans that had been issued and taken out during the 1920s and early 1930s were cancelled. David Andelman notes "refusing to pay doesnt make an agreement null and void. The bonds, the agreement, still exist." Thus, following the Second World War, at the London Conference in 1953, Germany agreed to resume payment on the money borrowed. On 3 October 2010, Germany made the final payment on these bonds.[345]
