The war in Syria has gone on for over many years and has claimed the lives of more than a quarter of more than a million people.
It is being fought between soldiers who support the president of Syria, Bashar al-Assad, and a group of fighters known as rebels, who don't want him to be in power anymore.
Because it is being fought between two sides within the same country, it is known as a civil war.
There was a significant battle in the Syrian city of Aleppo recently, which was part of this conflict.
The war has meant that millions of ordinary people living in Syria have had to escape from their homes in order to find somewhere safer to live.
Some have stayed in Syria, while others have left the country entirely.
Many of those that remain in Syria have run away from the cities to seek safety in the countryside. Lots of children can no longer go to school because their schools have been destroyed or there are no teachers where they have moved to.
Of those that have left Syria, many have fled to the neighbouring nations of Jordan, Lebanon, Turkey and Iraq.
When people are forced to leave the country where they live like this, they become known as refugees. The conflict in Syria has caused one of the largest refugee movements in recent history.
Many refugees have made the decision to try to reach Europe, which can be a long and dangerous journey. This is because some countries in Europe have said they will accept refugees who want to start a new life here.
