How did world war one change the world ?

IT CHANGED THE WORLD

Explanation: WORLD WAR II HAPPENED SO THAT'S HOW IT CHANGED THE WORLD

t became known as the Great War because it affected people all over the world and was the biggest war anyone had ever known.

It even came to be known as 'the war to end all wars', as no conflict before World War One had caused destruction on this scale before. People wanted to believe that nobody would ever want to go to war again after it. (Sadly, we know it was not to be the last devastating war that the world would experience).

Millions of people - both soldiers and ordinary citizens - lost their lives. Of those who did come home from the war, many were injured physically or struggled mentally as a result of what they had experienced.

On 11 November 1918, the guns fell silent and the war came to an end, but its impact was felt for many, many years after.

World War One changed the world in ways that nobody could have imagined. Here, we take a look at how.

New technology

One of the most significant impacts of World War One was huge advances in technology, which would transform the way that people all around the world travelled and communicated, in particular, in the years after the conflict.

New weapons and technologies were developed and used that led to more destruction than any war had seen in the past.
