The second Sudanese civil war started in 1983 and ended in 2005.
The war was about becoming an Arabic country. The north was mostly Muslim and the government wanted Sudan to be an all Muslim country, but many people in the south were of diverse religions and did not want to practice the Islamic faith.
During this time millions of people were killed, imprisoned, tortured, kidnapped or enslaved. Many families were separated and some people were unable to return home.
During this time there was something called the Lost Boys. They were either displaced or didn't have a family and would travel in desperation through many countries surround Sudan. They were looking for a safe heaven or a place were they could eat or drink.
