Over the past six months, nearly two million Iraqis have been forced to leave their homes as they flee tribal violence and ISIS advances.

In those hasty last moments, there's no time to thougtfully pack a suitcase and get your house in order. In most cases, these refugees could grab only a few small items, which grow heavy with nostalgia the longer these people are displaced from their homes.

Anwar Nassir: The drum maker said he had to leave most of the musical instruments he handcrafts behind when ISIS militants advanced on his town; after he ensured his family had safely departed, he was left with just a small motorbike to carry his belongings, including one handmade instrument. "They can take whatever they want, but I pray that they will have left my instruments," he said. | (Matt Cardy/Getty Images)

After speaking with Iraqi Christians at a refugee camp in Erbil, Iraq, photographer Matt Cardy created portraits of his subjects with the items they hold most dear. Many had less than an hour to pack before running, and while the refugees have found some semblance of safety in hastily built camps in the region, there is no guarantee they will be able to go home again. If they are lucky enough to one day return, the refugees said they fear there will be nothing left to greet them.

Below, moving portraits of the refugees and their cherished possessions.
