Since the First World War, countless lives have been shattered by conflict. Refugees across the globe have had to leave their homes and make journeys to settle somewhere else.
This is still happening today. But what drives this displacement? Why do people leave their homes?
Military conflict took place during every year of the 20th Century. There were only short periods of time that the world was free of war. The total number of deaths caused by war during the 20th Century has been estimated at 187 million and is probably higher.
