In its five years of existence, South Sudan has had a turbulent history.

After securing independence from Sudan in 2011 following decades of fighting, the oil-rich country set out on what it hoped would be a prosperous path. Just two years later, however, South Sudan plunged into civil war following a dispute between President Salva Kiir and Vice President Riek Machar.

South Sudan has shown small signs of reconciliation after fighting that has killed thousands and displaced millions of its citizens. A tentative peace agreement was signed in August 2015, and Machar recently returned to the capital Juba to re-take-up his post as vice president.

But problems abound: As well as ongoing clashes and a dysfunctional government, South Sudan is facing the worst food crisis in its short history, with almost half of the population at risk of going hungry in summer 2016.
