As a result of the Syrian civil war and the accompanying war against ISIS, approximately 4.8 million people in the surrounding area are now refugees, according to the United Nations.
These people have lost their homes, then fled on foot or on small rafts across the sea, all in the hopes of building a stable life for themselves and their families in Europe and beyond. And with people flooding into other nations, the Syrian refugee crisis has tested the resolve — and tolerance — of many nations around the world.
Here is what that crisis looks like:

A Syrian girl plays outside a tent camp on the outskirts of Izmir, Turkey on April 27, 2016.
A month earlier, the EU reached a deal with Turkey stipulating that if refugees arriving in Greece do not apply for asylum in Europe or if their claim is rejected, they will be sent back to Turkey, where their journey began.
,br>As a result, many refugees are stranded in Turkey, hoping to settle there permanently. With limited healthcare and education, and without stable housing, many are forced to squat on empty land or unused buildings, living in tents or makeshift structures and under the constant threat of being relocated to one of the 25 official camps elsewhere in the country.
Although many have been given restricted work permits allowing them to work various jobs, the long hours and minimal pay only provide enough money for basic necessities. Most cannot afford rent. Chris McGrath/Getty Images
