Wwi Start And End: The Definitive Timeline From 28 July 1914 To 11 November 1918
The First World War began on 28 July 1914 and concluded with an armistice on 11 November 1918, marking a definitive start and end to four years of global conflict. This timeline outlines the critical events that propelled Europe from a localized Balkan crisis into a world war and then toward the armistice that reshaped the international order. The following details trace the major political, military, and diplomatic milestones between these two fixed dates.
July 1914: The Spark In The Balkans
The immediate catalyst for the war was the assassination of Archduke Franz Ferdinand of Austria-Este in Sarajevo on 28 June 1914. This event set in motion a rigid chain of alliances and mobilizations that made a large-scale conflict increasingly likely. The Austro-Hungarian Empire, with the backing of Germany, issued an ultimatum to Serbia, and when the terms were not fully accepted, war was declared on 28 July 1914.
- 28 June 1914: Archduke Franz Ferdinand and his wife Sophie are assassinated in Sarajevo by Gavrilo Princip, a Bosnian Serb nationalist affiliated with the group Mlada Bosna.
- 23 July 1914: Austria-Hungary delivers the July Ultimatum to Serbia, containing demands that effectively compromise Serbian sovereignty.
- 28 July 1914: Austria-Hungary declares war on Serbia, activating the complex web of European alliances.
Russia, bound by a treaty obligation to support Serbia, begins partial mobilization on 30 July. Germany, viewing this as a threat, demands that Russia halt mobilization, which is refused, leading Germany to declare war on Russia on 1 August and on France two days later. The violation of Belgian neutrality to attack France brings Great Britain into the war on 4 August, solidifying the conflict as a world war.
The War Expands: 1914 To 1916
The initial phase of the war, often referred to as the "Race to the Sea," resulted in a static line of trenches stretching from the English Channel to the Swiss border. This period of attrition on the Western Front included the brutal battles of Ypres and the Somme, while the Eastern Front saw massive engagements between the Central Powers and Russia.
- Invasion of Belgium (August 1914): German forces execute the Schlieffen Plan, leading to the capture of Brussels and atrocities at Leuven and Dinant, galvanizing international opinion against Germany.
- First Battle of the Marne (September 1914): The French and British forces halt the German advance just outside Paris, ensuring the continuation of the war in the west.
- Gallipoli Campaign (1915): Allied forces launch a naval operation to secure a sea route to Russia, which ultimately results in a costly military failure and contributes to the downfall of the Ottoman Empire.
- Battle of Verdun (February to December 1916): One of the longest and bloodiest battles in history, where French forces successfully defend the fortress city against massive German assaults.
- Battle of the Somme (July to November 1916): A joint British-French offensive intended to relieve pressure on Verdun, resulting in over one million casualties with minimal territorial gain.
By 1916, the United States, though officially neutral, had become a critical supplier of loans and materiel to the Allies. The sinking of the RMS Lusitania in 1915 and the resumption of unrestricted submarine warfare in 1917 were key factors that moved the U.S. toward entry into the conflict.
1917: The Turning Point
The year 1917 proved decisive. The Russian Revolution led to the abdication of Tsar Nicholas II and the subsequent Treaty of Brest-Litovsk, which removed Russia from the war and allowed Germany to transfer millions of troops to the Western Front. However, the entry of the United States into the war in April 1917 counterbalanced this advantage by bringing fresh manpower and industrial capacity.
- February 1917: Germany resumes unrestricted submarine warfare, sinking American merchant ships.
- 6 April 1917: The United States declares war on Germany.
- 8 March 1917 (February Revolution): Czar Nicholas II abdicates, leading to the establishment of the Provisional Government in Russia.
- 7 November 1917 (October Revolution): The Bolsheviks seize power in Petrograd and subsequently sign the Treaty of Brest-Litovsk, ending Russia's participation in the war.
The Final Push: 1918
In 1918, Germany launched a series of massive offensives on the Western Front in a desperate attempt to defeat the Allies before American forces could tip the balance. These spring offensives made significant gains but exhausted German resources. The Allies, spearheaded by fresh American divisions, launched the Hundred Days Offensive in August 1918, pushing the Central Powers back continuously.
The collapse of the Ottoman Empire and the Austro-Hungarian Empire preceded the end of the war on the Western Front. Political upheaval and military defeat created conditions where an armistice became the only viable option for the German leadership.
November 1918: The End
The Armistice of 11 November 1918, effective at 11:00 a.m., marked the end of hostilities on the Western Front. While the armistice did not constitute a formal peace treaty, it signaled the cessation of the fighting that had defined the latter part of the war. The terms of the subsequent Treaty of Versailles, signed in 1919, officially ended the state of war between Germany and the Allied Powers.
To understand the scale of the conflict between the Wwi start and end, one must examine the casualty figures. Estimates of total military and civilian deaths range from 16 to 20 million, with another 21 million wounded. The war fundamentally altered the political landscape, dismanting empires and setting the stage for the geopolitical tensions of the 20th century.
Reflecting on the timeline from 28 July 1914 to 11 November 1918, it is clear that the Wwi start and end bookends a period of unprecedented destruction. The conflict reshaped national borders, redrew the map of Europe, and established the United States and the Soviet Union as the dominant global powers of the ensuing century.
