If you had one minute to flee your home in a crisis, what would you think to take with you? This is the question refugees face every day. Today, there are over 45 million people that have been displaced because of war or persecution around the world, reports the UNHCR (The United Nations High Commission for Refugees), hoping to engage the public to think about the heart-wrenching decisions families are forced to make when they flee their homes.

The project was inspired by a series of images taken by photographer Brian Sokol called "The Most Important Thing."

Varvara from Georgia says she had to run, when she read in a newspaper that her only brother had been killed. "The most important thing? For mothers the choice is easy. I took my children. Without them I would not have left anywhere." (R.Kostrzynski/UNHCR)

Congolese refugee Florence Mukeshimana and her five children escaped to Uganda from eastern DRC because of fighting between the army and rebel forces. She initially hid in the bush and later found out that her husband had been blown up by a land mine. "When I found out he was dead I lost hope and decided to leave the country." This old and worn saucepan is the only thing she has left after selling the rest of her belongings along the way. She made sure she kept it so she could cook for her children. (L. Beck/UNHCR)

Noela Sumaili, fled the Democratic Republic of Congo after her husband was caught by soldiers. She believed she would never see him again. The most important thing she brought with her was a bicycle.

We use it for small business, it helps our family." (M. Senelle/UNHCR)
