Hello, friends. Welcome to a new Happy Learning video. Today I want to talk to you about one of the most tragic moments in the history of humanity. Today we are going to learn about the First World War, also called the Great War.

The First World War started in 1914 and ended in 1918. It created conflicts between the major   at the time. On one side, there was the Triple Entente, also known as the  , consisting of Russia, France, and Great Britain. On the other side, there was the Triple Alliance. It was originally Germany, the Austro-Hungarian Empire, and Italy, although Italy switched sides at the height of the war in 1915.

The main cause of this war was imperialism, meaning that all important countries wanted to conquer territories, both within and outside Europe. They wanted to control   or several colonies. In that era, in Africa and Asia, for example, there were many places where civilization had not arrived yet, and the great European powers wanted the   and richness from those territories.

Also, the Industrial Revolution in Europe had made lots of people  , so there were also severe social conflicts.

All that tension had to explode, and the war exploded with the murder of Archduke Franz Ferdinand of Austria, heir of the Austro-Hungarian Empire. The murder was committed by   from a Serbian group called the Black Hand, in response to the Austro-Hungarian Empire’s attempts to keep the Balkan territories.

This murder made the war begin between Serbia and the Austro-Hungarian Empire, and from then on there was  . Lots of other countries joined the war defending their blocs.

The Triple Entente, made up of Russia, France, and Great Britain, supported Serbia. During the war, more and more countries joined them, such as the United States, Japan, and Canada. Germany and Italy, as members of the Triple Alliance, joined the Austro-Hungarian Empire, and this bloc had countries such as Turkey and Bulgaria, among others, join them.

From that point on, there were four years of a terrible war, with more than 50 million deaths and the   of Europe, the Far East, Africa, and areas in the Pacific, including gorgeous cities full of history.

But in the end, in 1918, the war finally ended with the Triple Entente as  , that is, France, Great Britain, and the rest of their allies, and with the defeat of the Triple Alliance, the bloc led by Germany and the Austro-Hungarian Empire.

By the way, Russia left the war because in its territory there were great revolutions.

Starting between 1919 and 1920, there were various treaties signed. These treaties decided the situation between the victors and  . The most important   was the Treaty of Versailles.

Sadly, this treaty was the origin of the Second World War, which we will learn about in another video.

Before I say goodbye, I would like to say that at Happy Learning we hope this never happens again, and that everyone in this world respects and helps each other so we can all live in peace. Goodbye, friends, and don’t forget to subscribe to Happy Learning TV.
