The First World War had begun in 1914 and continued for the next 4 years up to 1918. It led to a great economic and political instability in many countries of the world. It was a war among all the leading industrial nations. Since it was the first industrial war many heavy types of equipment were used. Many soldiers were recruited and most of them were either injured or dead. Since the industries were pushed to produce war related goods and men were sent on the battlefield, the women began to work in the industries. It had also ended the economic links between different countries. Hence it is said that there was no war like the First World War.
