War declarations
Germany declares war on Russia, France, and Belgium. -
First Battle of the Marne
First Battle of the Marne begins. The Germans had advanced to within 30 miles of Paris, but over the next two days, the French are reinforced by 6,000 infantrymen who are transported to the front by hundreds of taxis. The Germans dig in north of the Aisne River, and the trench warfare that is to typify the Western Front for the next four years begins. -
Britain and France declare war on the Ottoman Empire.
The Ottoman entry into World War I began on 29 October 1914 when it launched the Black Sea Raid against Russian ports. Following the attack, Russia declared war on the Ottoman Empire on 2 November, followed by their allies (Britain and France) declaring war on the Ottoman Empire on 5 November 1914. -
ypres
The Second Battle of Ypres begins. The German army initiates the modern era of chemical warfare by launching a chlorine attack on Allied trenches. Some 5,000 French and Algerian troops are killed. By war’s end, both sides have used massive quantities of chemical weapons, causing an estimated 1,300,000 casualties, including 91,000 fatalities. -
lusitania
The British ocean liner Lusitania is torpedoed by a German U-boat off the southern coast of Ireland. It sinks in just 18 minutes, and nearly 1,200 people are killed, including 128 U.S. citizens. The ship had been carrying over 170 tons of rifle ammunition and artillery shells, and Germany felt fully justified in treating the Lusitania as a legitimate target in a declared war zone. -
Verdun
The Battle of Verdun begins. Over the next 10 months, the French and German armies at Verdun, France, suffer over 700,000 casualties, including some 300,000 killed. By the battle’s conclusion, entire French villages had been wiped from the map; they were subsequently memorialized as having “died for France.” More than a century after the battle’s conclusion, over 10 million shells remained in the soil around Verdun, -
Somme
The First Battle of the Somme begins. The British offensive is intended to draw German attention from Verdun, and in that regard only could it be considered a success. The nearly 20,000 killed in action on July 1 marks the single bloodiest day in the history of the British army. By the time the Somme campaign ground to a halt some four and a half months later, the combined casualties of both sides topped 1,000,000. -
Russia gives up
After months of delays, the Soviet government concludes a separate peace with the Central Powers when it accepts the Treaty of Brest-Litovsk. Russia surrenders its claim to Ukraine, to its Polish and Baltic territories, and to Finland. -
Tsar leaves the thrown
Tsar Nicholas II leaves the throne after a week of riots in the Russian capital of St. Petersburg. The Russian Revolution saw the overthrow of the Romanov dynasty and, ultimately, the rise to power of Vladimir Lenin and the Bolsheviks. -
The United States declares war on Germany
The United States declares war on Germany. In his address to Congress four days earlier, U.S. Pres. Woodrow Wilson had cited Germany’s practice of unrestricted submarine warfare and the “Zimmermann Telegram” as key reasons behind the abandonment of his long-standing policy of neutrality. -
A British attack at Cambrai,
A British offensive at Cambrai, France, marks the first large-scale use of tanks in combat. Attacking with complete surprise, the British tanks ripped through German defenses in depth and took some 7,500 prisoners at low cost in casualties. Bad weather intervened, however, and adequate infantry reinforcements were not available to capitalize on the breakthrough. Within two weeks the British had been driven back almost to their original positions. -
conclusion of armistice
Germany and the Allies conclude an armistice based largely on Wilson’s Fourteen Points. With the threat of revolution gripping German industrial centers and Allied armies on the verge of flanking the entire German defensive line, the ability of Germany to continue the war seemed doubtful at best. -
Sparks that led to ww2
Nevertheless, a group of hard-core militarists, led by Erich Ludendorff, would perpetuate the “stabbed in the back” myth, claiming that Germany had been betrayed by its politicians and that the German military had been unbeaten in the field. This sentiment would do much to propel the ascent of Adolf Hitler to power in 1933. -
signing of the treaty of versailles
signed on June 28, 1919, by the Allied and associated powers and by Germany in the Hall of Mirrors in the Palace of Versailles and went into effect on January 10, 1920. The treaty gave some German territories to neighbouring countries and placed other German territories under international supervision.
