World War I, also known as the Great War and First World War, was a deadly global conflict that originated in Europe. Beginning from 1914 and lasting until 1918, the First World War left with an estimated nine million combatant deaths and 13 million civilian deaths as a direct result of the conflict.

World War I is a topic covered in the world history segment of the UPSC Mains examination. As such candidates appearing for the exam will find the information from this article useful.

Origins of World War I

Towards the end of the 19th century, the growing rivalry between European nations became all too apparent. Germany, upon its unification in 1871, was becoming an industrial power and other nations of Europe, specifically France and Britain, felt threatened by this.

Around this time the fracturing Ottoman Empire gave birth to new countries in the Balkan region. One of them, Serbia, was gaining land and power at the expense of the empire of Austria-Hungary. To counter this threat, along with any future ones, the Austro-Hungarian Empire formed an alliance with Germany and Italy to defend each other. 

In response, Britain, France and Russia formed the Triple Entente for the same purpose.

During the 1900s both Britain and Germany added bigger and better battleships to their naval arsenals. The rest of Europe also followed suit. By 1914, most of the European countries had their armies ready for war. All it needed was a spark to ignite it. That spark came when Archduke Franz Ferdinand was assassinated in Sarajevo, Bosnia on June 28, 1914.

Franz Ferdinand was the heir to the throne of Austria-Hungary and the man who shot him was a Serb nationalist, Gavrilo Princip. Gavrilo was protesting against  Austro-Hungarian rule in Bosnia. Austria-Hungary declared war on Serbia, prompting Russia to mobilize its army to defend Serbia. Germany, in turn, declared war on Russia and on France. To invade France a large German army marched through Belgium, violating its territorial integrity. This drew Britain into the war, since, in 1830, it had made an agreement to defend Belgium if it was ever attacked.

The making of a Global War

The war drew in many European powers at the time along with their overseas colonies. They were divided into two groups – the Allied Powers and the Central Powers. The Central Powers were made up of Germany, Austria-Hungary and Turkey, while the Allies including France, Britain and its empire, Russia, Italy, Japan and from 1917, the United States of America. The war was fought along two main lines, or fronts. There was the Western Front, which ran from Belgium, through France to Switzerland, and the Eastern front which ran from the Baltic to the Black Sea. There were also sporadic fighting in the Middle East and along the border between Italy and Austria.

For a better understanding of the causes of World War I, we have given a table below outlining the events before and during the conflict for easy reference.

Events Before and During World War I

What made World War I different?

The factor that made World War I different was the fact that it was fought from parallel lines of trenches separated from only a short stretch of ground known as “no man’s land”. Trench warfare was necessary as the power, speed and accuracy of the weapons used on both sides made open battle impossible. When soldiers did leave the trenches to launch an attack, often only a few metres of the ground was gained and the cost of casualties was enormous. This led to a stalemate situation that lasted from the end of 1914 until the summer of 1918. Even the use of new weapons such as tanks, nerve gas and aeroplanes did little to change the situation.

The Tide Turns

At the end of 1917, following the Russian Revolution, Russia had started peace talks with Germany and German soldiers who had been fighting on the Eastern Front were able to join the fighting in the west, For a while, they outnumbered the Allied forces, but by 8 September 1918 over 1,20,000 well-trained and well-equipped forces of the United States joined the allies in France. This changed the balance power in favour of the Allies. By the End of October, all German occupied-France and Belgium had been reclaimed with Turkey and Austria-Hungary having been defeated.

End of the War 

In Germany, people were running short of food and fuel. The German navy mutinied and there was widespread unrest. On November 9, the German ruler, Kaiser William II, abdicated and on November 11. 1918 an armistice was signed between Germany and the allies, bringing the fighting to an end. In January 1010, the Allies met at the Paris Peace Conference, which formally ended the war. It drew up the Treaty of Versailles, which imposed a harsh peace upon Germany and laid the responsibility of starting the conflict squarely on Germany’s shoulders.

As part of the treaty, Germany was forced to give up its colonies overseas and vast sums of money to its former enemies. It also had to return Alsace-Lorraine to France. The wider implications of the treaty would be one of the causes of World War II.
