With inter-ethnic clashes in South Sudan and the nation as a whole bracing itself for upcoming elections, the western region of Darfur has been reminded that the war is not over. In mid-September, attacks by the Sudan Armed Forces around Korma North Darfur were reported to have killed 16 civilians, wounded dozens more, and destroyed several villages. An estimated 2.7 million people still live in displaced persons camps in Darfur and 200,000 refugees remain in Chad, unable to return home for fear of precisely this kind of violence between the rebel groups and the Sudanese government.

Efforts to address the current situation in Sudan continued this month with an international conference on Sudan in Moscow, attended by the UN, AU, and League of Arab States. Peace talks on Darfur are set to resume by the end of October in Doha.

In an unprecedented visit by an American secretary of state, Hillary Clinton visited Goma in eastern Congo this week, in order to call attention to the region's ongoing conflict, which is marked by extreme brutality and widespread sexual violence. Secretary Clinton's visit comes admit increased concern for the region, as hope vanishes that the combined Rwandan-Congolese operation launched last January against rebel groups would finally bring an end to the violence.

Instead, the joint military operation provoked revenge attacks and drove more than 500,000 people from their homes. The number of internally displaced persons in the Congo now stands at two million, according to the U.N. Office for the Coordination of Humanitarian Affairs (OCHA). A spike in rape cases since January is being blamed on the overstretched and unpaid Congolese army, with the number of rapes doubled or tripled in the areas government soldiers are deployed.

Just days before Secretary Clinton's arrival, Congo's President Joseph Kabila and Rwandan President Paul Kagame held a rare meeting on the border. Former rivals, the two leaders agreed to plan joint economic initiatives and to revive the Joint Permanent Commission for cooperation between the two countries that has not been in operation for 21 years.

Last week, communities around the world observed World Refugee Day in order to draw attention to the plight of the 42 million refugees today who have been forced to flee their homes because of conflict, persecution, or natural disasters. Among the most vulnerable populations in the world, refugees often lack access to clean water, food, sanitation, shelter, and health care.

Although conflicts and disasters have uprooted people throughout human history, the legal definition of a "refugee" developed relatively recently in response to the Holocaust.

During World War II, the Nazis deported between seven and nine million people, mostly Jews, to concentration camps across Europe. Within months of Germany's surrender in May 1945, some six million displaced persons were repatriated, although between one and a half million and two million DPs refused repatriation because of the destruction of their communities and postwar antisemitism.

In response, the United Nations established a new legal definition of a "refugee" and outlined new protections to which they are entitled. The 1951 Convention on Refugees defined a refugee as someone who:

"...owing to a well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group or political opinion, is outside the country of his nationality and is unable, or owing to such fear, is unwilling to avail himself of the protection of that country; or who, not having a nationality and being outside the country of his former habitual residence as a result of such events, is unable or, owing to such fear, is unwilling to return to it."

The 1951 document limited the definition of a refugee to those displaced in Europe before 1951. An additional protocol in 1967 removed both the time and location limitations. Today, the United Nations High Commissioner for Refugees estimates there are 42 million refugees and displaced people in the world today.
