- While visiting Sarajevo on the 28th of June, Archduke Franz Ferdinand and his wife Sophie are assassinated by Serb nationalist Gavrilo Princip. In reaction, Austria-Hungary sends an ultimatum to Serbia, whose contents are deliberately made unacceptable to the Serbs. Austria-Hungary declares war on Serbia shortly after receiving German backing. Russia in turn declares war on Austria-Hungary and Germany. Germany, wanting to knock France out of the war before it can assist its Russian ally, declares war on France on August 3rd.
- When Germany invades neutral Belgium to execute the Schlieffen Plan, the British Empire declares war on Germany. The German advance to Paris is halted at the Marne and a series of flanking attempts, known as the Race to the Sea, prove unsuccessful. The war in the West grinds down to a halt.
- The Germans are much more successful in the East, repulsing the Russian invasion of East Prussia and defeating the Russians at the battles of the Mazurian Lakes and at Tannenberg. The architects of these victories, Field Marshal von Hindenburg and General Ludendorff, would play key roles in the final German victory.
- The Ottoman Empire joins the Central Powers in October, after a dispute with Britain about the confiscation of ships being built for the Empire.

A British invasion of Mesopotamia is repelled and the remaining troops retreat to Kut, where a disastrous siege will start.
- A German submarine sinks the Lusitania. A severe backlash in the United States leads to Germany abandoning its unrestricted submarine warfare, which had hoped to strangle Britain into submission. Many speculated that a continuation of the unrestricted submarine warfare could have led to the entry of the United States into the war.
- The Battle of Verdun starts, attempting to bleed the French Army dry. In reality, all sides bleed equally in a battle which soon loses its military objective. A similar attempt against the British forces at the Somme has the same outcome. 1916 also saw the first use of tanks at the Battle of the Somme.
- In the East, the Brusilov offensive is launched. While very successful at first, the offensive doesn’t manage to either knock the Austro-Hungarians out of the war or drive Germany from Russian Poland.

- A great Allied spring offensive, designed at breaking the German lines before their reinforcements arrive, is repulsed at great cost of life.
- Operation Teutoburg is launched, attempting to kick Greece out of the war. Instead of assaulting the Salonika stronghold head on, the Central Powers make extensive use of specialized storm-troopers and so called "infiltration" tactics. The defenders at Salonika are pinned down while the rest of the German-Bulgarian forces sweep through Greece. Athens falls on July 3rd, causing the Greek government to surrender. The western forces at Salonika are evacuated soon afterwards.
- Anti-Bolshevik White Russian forces of the "Volunteer Army" under General Lavr Kornilov battle pursuing Red forces across the frozen Kuban steppe from February to May.

- Successful Allied tactics against Germany's U-boats and the blockade of Germany itself leads to a desperate sally of the Hochseeflotte, now led by Admiral Hipper. The Second Battle of Jutland ends in a tie, but the shock of being assaulted forces the Royal Navy to break their blockade. The end of the blockade and the influx of Ukrainian grain ends all fears of Germany being starved into submission. Meanwhile, Kaiser Karl von Habsburg issues the "Volkermanifest", promising a United States of Greater Austria after the war is won, placating the near-rebellion minority nations of his empire.
- After almost a month of negotiations between the anti-Bolshevik KOMUCH and Siberian governments, Admiral Alexander Kolchak reluctantly launches a British-backed coup to unite the fractious Whites.

- On March 2nd the Germans launch their Great Offensive at St. Mihiel, south of Verdun. Their infiltration tactics prove to be successful, with Nancy falling on the 16th. The French organize an ad hoc defense, leaving their flank exposed. An attack on Rheims on the 26th splits the Allied forces in two. An attack on Chateau-Thierry meant the French couldn’t retreat back to the Marne. In effect, the entire French army was forced to retreat south and Paris was placed under siege.
- Operation Radowitz is launched on the 11th of March, attacking the Italian forces from Trento instead of the Piave. Vicenza and Verona fall on the 24th, pinning the Italians between two Central armies after Venice was reached on the 10th of April. The Siege of Venice would last until July, but with most of the Italian army occupied the rest of Italy lay defenseless, with Rome falling on August 1st. Italy would surrender a few days later. The surrender of Italy meant the road to Southern France was now open, with Marseilles falling in September.
- As Italy collapsed, Empress Zewditu of Ethiopia approached Germany and offered to join the Central Powers in exchange for being able to annex the lands Italy had stolen from her. Lacking any interest in them, the Kaiser agrees.
- Allied setbacks would lead to Allenby, and most of his troops, being redeployed to France. Allenby’s successor, Sir William Marshall, is forced to slowly retreat because of a lack of manpower.
- The retreat of the French Army leads to the positions of the BEF becoming indefensible. Most of the British forces are evacuated at Dieppe in June, leaving the French on their own. At this point the French Army, battered, war-weary and with little hope of victory was in open rebellion. With a second mutiny, a general uprising of the working classes imminent, the fall of Paris a certainty and Marseilles in German hands, the French government capitulated on the 4th of October, ending the war in Europe. One month later, the Central Powers and the remaining Allied Powers signed a ceasefire in Copenhagen.
- The fall of France, Russia, Italy and their allies in the Balkans reduced the Entente to the British Empire, Japan and Portugal. While none of these countries were under direct German threat, none was able to pose a threat to Germany likewise. The battle between Germany and Britain continued for two more years by proxy, in Ireland and elsewhere, while the otherwise victorious Central Powers divided up their conquests...

The Belgian Congo was given to Germany and Wallonia east of the Meuse, the location of most Belgian industry would be occupied as long as the German government deemed necessary. The Grand-Duchy of Luxembourg would become a constituent state of the German Empire.
- In the East, the acquisitions of the Treaty of Brest-Litovsk were organized into a series of puppet states. Estonia and Latvia were fused into the United Baltic Duchy, with Adolf Friedrich von Mecklenburg becoming its first Grand Duke. The Kaiser's brother Heinrich became King Genrikh I of White Ruthenia (Belarus). Poland and Finland became independent states under German protection, with the Kaisers brother-in-law Friedrich-Karl von Hessen becoming King of Finland.

The peace itself was signed at 11 AM on the 11th of November, 1921, ending the Weltkrieg after seven long years.
- The Confédération Générale du Travail (CGT), led by anarcho-syndicalist Emile Pouget, declares a general strike in reaction to the bloody defeat of the French army during the German Great Offensive and the second mutiny. Its main aim was an immediate end to the war. After the fall of Paris, the government of Georges Clemenceau was replaced by a Provisional Government under Aristide Briand.
- The Southern White Russians begin their "Volga Campaign" with the capture of the city of Tsaritsyn. Led by General Pyotr Wrangel, the Whites swiftly seize Saratov, but are halted at Samara by Leon Trotsky. It takes until July for a Siberian White counter-offensive to force Trotsky to withdraw and surrender Samara, ultimately uniting the two largest White fronts.
- In the Baltics, the White Russian Northwestern Army under General Nikolai Yudenich launches its offensive towards Red Petrograd. The outnumbered Reds are quickly forced to withdraw to Petrograd itself, and the Whites (with White Ruthenian and Baltic support) place the city under siege.
- The Southern and Siberian Whites meet in the recaptured city of Ufa to negotiate a union of their governments. It is ultimately decided that Alexander Kolchak will remain supreme military commander of all White Russian forces, with Sergey Sazonov acting as prime minister. Most importantly, however, the Siberian Whites agree to follow the example of the Southern Whites, and cut ties with the Entente. Petrograd falls shortly afterwards to Yudenich's troops, and he presents the city as a gift upon also ratifying his support for the new, unified Provisional All-Russian Government.
- Jacobin radicals, inspired by their Russian brethren and Leninist theories about a revolutionary vanguard start a series of attacks on government officials and public buildings, ending the chance of the CGT and Provisional Government of reaching any agreement.

- Though Moscow had been under siege from a combined army of Whites since November of 1919, it takes until January 22nd, 1920 for the Bolsheviks to finally submit a formal surrender. Outnumbered, outgunned, and crippled by starvation and desertion, the Reds have little choice but throw themselves at the mercy of the Provisional Government. The Whites stand victorious at the formal conclusion of the civil war.
- The White Russians send a delegation of Alexander Kolchak, Sergei Sazonov, and Alexander Kerensky to ratify a modified version of the Treaty of Brest-Litovsk, despite furious protestations from nearly all elements of Russian society. With the nascent Russian Republic in almost as poor shape as the Bolsheviks had been in 1918, the Russians have little choice but agree to German demands, lest they face "punitive action" by the Kaiser's armies.

As his son Otto is only 9, a regency council is formed. Conspiracy theories about a possible poisoning spread, and when the federalization project is officially dropped on the 2nd of April, chaos erupts. With investor panic threatening to trigger an economic crisis on top of the political one, the Regency Council resumes talks on the federalization plan and begs for German help. Under German supervision, Bohemia, Bosnia, and Galicia-Lodomeria are granted home rule within Cisleithania, while Croatia is granted similar status within Hungary. Ukraine, which was part of the Austrian sphere of influence becomes part of German's alliance, as a 'reward' for the German mediation.

- In Russia, a coup is attempted by a loose coalition of businessmen, industrialists, centre-right conservatives, and Siberian autonomists, all of whom are united chiefly by strong anti-German resentment. Alexander Kolchak, despite having little involvement with the plot, is declared provisional dictator. However, only a handful of units in Siberia side with the plot, and all ultimately agree to stand-down rather than fight the army units sent to suppress them. Seeing the writing on the wall, the plotters disperse, with Kolchak accepting an Anglo-Japanese offer to be installed as an anti-German pretender in the "Russian Republic" of Transamur.
- Seeing the chaos engulfing Russia in the wake of the Kolchak Putsch and resentful of broken promises for autonomy, the Don, Kuban, and Terek Cossacks mutiny on the urging of General Pyotr Krasnov.
