Hello, we are Guti and Leo and we are going to talk about the World War I.

2
00:00:06,379 --> 00:00:13,849
The war began in 1914 with the assassination of the Archduke Franz Ferdinand of Austria.

3
00:00:14,410 --> 00:00:21,109
His murder catapulted a war across Europe that lasted until 1918.

4
00:00:22,129 --> 00:00:29,949
During the conflict, Germany, Ottoman Empire, Austro-Hungarian Empire and Bulgaria

5
00:00:29,949 --> 00:00:39,630
fight against United Kingdom, United States, Russia, Japan, Canada, Italy, France and Romania.

6
00:00:41,090 --> 00:00:47,990
Thanks to the new military technologies and the 10th World War, there were a lot of carnage

7
00:00:47,990 --> 00:00:58,429
and destruction. They died 16 millions of people. There were disorders, traumas and

8
00:00:58,429 --> 00:01:06,930
mental illness caused by the war. To understand why so many countries were in the war is because

9
00:01:06,930 --> 00:01:14,129
before the war there were a lot of alliances and rivals. France and Germany were rivals

10
00:01:14,129 --> 00:01:27,370
because they both were in war between 1817 and 1871. Russia and Austro-Hungarian Empire

11
00:01:27,370 --> 00:01:35,969
were also rivals because they both wanted volcanic territories, and when the Austro-Hungarian

12
00:01:35,969 --> 00:01:42,170
Empire declared war on Serbia, Russia helped Serbia because they were an alliance.

13
00:01:42,170 --> 00:01:45,769
Some of the most important battles were these.

14
00:01:45,769 --> 00:02:03,769
Lemberg in August 1904, Marnay in August 1904, Lagos de Massoula, September 1904, Calipoli, February 1915, Tannenberg, August 1914.

15
00:02:03,769 --> 00:02:10,710
These battles were Germany versus Russia. Only in this battle 182,000 people died.

16
00:02:10,710 --> 00:02:25,710
Cyprus, October 1914. In 1917, Russia led the war with the first little street. In Russia, the socialist revolution defeated the Tsar Nicholas II.

17
00:02:25,710 --> 00:02:33,710
In this year, the United States entered in the war as a triple entente member. This made more powerful the triple entente.

18
00:02:33,710 --> 00:02:39,710
Germany, after all the years of war, was in social and economic crisis.

19
00:02:39,710 --> 00:02:44,710
The emperor Guillermo II abdicated and Germany became a republic.

20
00:02:44,710 --> 00:02:54,710
The 11th of November 1917 Germany signaled the end of the fight in Copenhagen.

21
00:02:54,710 --> 00:03:00,710
The war ended with the trade of Versailles where all the countries that participated in the war signaled the peace.

22
00:03:00,710 --> 00:03:05,710
This happened in the 28th of June of 1918.

23
00:03:05,710 --> 00:03:13,710
At 1914 Christmas, the soldiers from both sides sent some Christmas carols to each other.

24
00:03:13,710 --> 00:03:16,710
In the war participated more than 30 countries.

25
00:03:16,710 --> 00:03:21,710
A third of the deaths were due to a pandemic.

26
00:03:21,710 --> 00:03:26,710
The Russian Empire was the largest with more than 12 million soldiers.

27
00:03:26,710 --> 00:03:31,830
and as several countries use toxic gases as a weapon.

28
00:03:32,490 --> 00:03:34,169
Thanks for listening.
