At the end of the war, Germany's defeat and widespread popular discontent triggered the German Revolution of 1918–1919 which overthrew the monarchy and established the Weimar Republic.
[2][3] According to biographer Konrad H. Jarausch, a primary concern for Bethmann Hollweg in July 1914 was the steady growth of Russian power, and the growing closeness of the British and French military collaboration.
It failed when Russia decided on general mobilization, and his own Army demanded the opportunity to use the Schlieffen Plan for quick victory against a poorly prepared France.
[5] The crisis came to a head on 5 July 1914 when the Count Hoyos Mission arrived in Berlin in response to Austro-Hungarian Foreign Minister Leopold Berchtold's plea for friendship.
His main concern was Russian border manoeuvres, conveyed by his ambassadors at a time when Raymond Poincaré himself was preparing a secret mission to St Petersburg.
"[6] Following the assassination of Archduke Franz Ferdinand in Sarajevo on 28 June 1914, Bethmann Hollweg and his foreign minister, Gottlieb von Jagow, were instrumental in assuring Austria-Hungary of Germany's unconditional support, regardless of Austria's actions against Serbia.
While Grey was suggesting a mediation between Austria-Hungary and Serbia, Bethmann Hollweg wanted Austria-Hungary to attack Serbia and so he tampered with the British message and deleted the last line of the letter: "Also, the whole world here is convinced, and I hear from my colleagues that the key to the situation lies in Berlin, and that if Berlin seriously wants peace, it will prevent Vienna from following a foolhardy policy.
He reportedly asked the departing British Ambassador Edward Goschen how Britain could go to war over a "scrap of paper" ("ein Fetzen Papier"), which was the 1839 Treaty of London guaranteeing Belgium's neutrality.
His civilian colleagues pleaded for him to register some febrile protest, but he was frequently outflanked by the military leaders, who played an increasingly important role in the direction of all German policy.
[11] Bethmann Hollweg remained in office until July 1917, when a Reichstag revolt resulted in the passage of Matthias Erzberger's Peace Resolution by an alliance of the Social Democratic, Progressive, and Centre parties.
That same July the strong opposition to him from high-level military leaders – including Hindenburg and Ludendorff who both threatened to resign – was exacerbated when Bethmann Hollweg convinced the Emperor to agree publicly to the introduction of equal manhood suffrage in Prussian state elections.
[12] The combination of political and military opposition forced Bethmann Hollweg's resignation and replacement by a relatively unknown figure, Georg Michaelis.
The Germans did not expect this and were delayed, and responded with systematic reprisals on civilians, killing nearly 6,000 Belgian noncombatants, including women and children, and burning 25,000 houses and buildings.
The German army had fought its way into a good defensive position inside France and had permanently incapacitated 230,000 more French and British troops than it had lost itself.
Some say it was a standoff, but most see it as a British victory and argue it marked the point at which German morale began a permanent decline and the strategic initiative was lost, along with irreplaceable veterans and confidence.
[16] In early 1917 the SPD leadership became concerned about the activity of its anti-war left-wing which had been organising as the Sozialdemokratische Arbeitsgemeinschaft (SAG, "Social Democratic Working Group").
On 17 January they expelled them, and in April 1917 the left-wing went on to form the Independent Social Democratic Party of Germany (German: Unabhängige Sozialdemokratische Partei Deutschlands).
Morale was at its greatest since 1914 at the end of 1917 and beginning of 1918 with the defeat of Russia following her rise into revolution, and the German people braced for what General Erich Ludendorff said would be the "Peace Offensive" in the west.
It prepared for the decisive strike with new armies and new tactics, hoping to win the war on the Western front before millions of American soldiers appeared in battle.
General Erich Ludendorff and Field Marshal Paul von Hindenburg had full control of the army, they had a large supply of reinforcements moved from the Eastern front, and they trained storm troopers with new tactics to race through the trenches and attack the enemy's command and communications centers.
Moving in small units, firing light machine guns, the stormtroopers would bypass enemy strongpoints, and head directly for critical bridges, command posts, supply dumps and, above all, artillery batteries.
The great German spring offensive was a race against time, for everyone could see the Americans were training millions of fresh soldiers who would eventually arrive on the Western Front.
"[22] By September 1918, the Central Powers were exhausted from fighting, the American forces were pouring into France at a rate of 10,000 a day, the British Empire was mobilised for war peaking at 4.5 million soldiers and 4,000 tanks on the Western Front.
"[24] At the same time, there was a level of anxiety; most commentators predicted a short victorious war – but that hope was dashed in a matter of weeks, as the invasion of Belgium bogged down and the French Army held in front of Paris.
[25] According to historian William H. MacNeil: Germany had no plans for mobilizing its civilian economy for the war effort, and no stockpiles of food or critical supplies had been made.
The causes involved the transfer of so many farmers and food workers into the military, combined with the overburdened railroad system, shortages of coal, and the British blockade that cut off imports from abroad.
Daily life involved long working hours, poor health, and little or no recreation, and increasing fears for the safety of loved ones in the Army and in prisoner of war camps.
Sailors mutinied at the prospect of a final battle against the British Navy, and by means of workers' and soldiers' councils, they quickly spread the revolt across Germany.
The new government led by the German Social Democrats called for and received an armistice on 11 November 1918; in practice it was a surrender, and the Allies kept up the food blockade to guarantee an upper hand in negotiations.
Due to German military forces still occupying portions of France on the day of the armistice, various nationalist groups and those angered by the defeat in the war shifted blame to civilians; accusing them of betraying the army and surrendering.
