July 11 marks the 25th anniversary of the Srebrenica genocide, the worst atrocity on European soil since the Holocaust.
In July 1995, Serb forces systematically killed more than 8,000 Bosniak Muslim men and boys in the so-called UN-protected enclave in Srebrenica, Bosnia and Herzegovina.
But what led to the massacre?
In the nineties, American genocide scholar Gregory H Stanton, examined the stages of genocide, which eventually became his "10 stages of genocide" theory.
Genocide is not committed by a small group of individuals, rather a large number of people and the state all contribute to genocide.
At each stage, preventive measures can stop the situation from deteriorating further, Stanton noted.
Bosnian Australian anthropologist Hariz Halilovic later added an eleventh stage particular to Bosnia's case - "triumphalism".
Here is how Stanton's 10 stages - and Halilovic's eleventh - relate to the Srebrenica genocide:
Stages one, two, three: Classification, symbolisation and discrimination
The idea of a Greater Serbia (including the territories of Bosnia, Kosovo, Croatia, Montenegro and other neighbouring countries) dates back to the 19th century, and was revived following the death of Yugoslav leader Josip Broz Tito in 1980.
With the decline of the Communist bloc, Serbian President Slobodan Milosevic and Serbian nationalists saw a chance to mobilise the masses in support of establishing a homogenous Serbian state.
In Milosevic's famous address to a crowd in Belgrade in 1989, he presented himself as the saviour of Serbdom and Europe. It enforced the notion of "us [Serbs] vs them".
Bosniaks were typically called Turks, Balije (a slur for a Bosnian Muslim) and branded as "terrorists" and "Islamic extremists".
Stage four: Dehumanisation
Many Serbs dehumanised Bosniaks, regarding them as Muslims who posed a threat to the Serbian hegemonist project.
"In order to mobilise domestic public opinion against the Muslims and to justify future acts against them in the eyes of the West, the Serbian leadership needed an image of Islam as a totalitarian, inherently violent, and culturally alien system on European soil," writes Fikret Karcic, professor at the University of Sarajevo, in his paper, Distorted Images of Islam: the case of former Yugoslavia.
"Such a distorted image had been provided by some influential Serbian orientalists, the Orthodox Church, and some historians."
Just as Nazis identified the Jews during the Holocaust, Biljana Plavsic, a genetic biologist who served as president of Republika Srpska (Bosnia's Serb-run entity) and is now a convicted war criminal, claimed in the early nineties Bosnian Serbs were racially superior to Bosniaks.
In 1994 she said she and other leaders of Republika Srpska were unable to negotiate with Bosniaks due to their genetic deformity.
Plavsic said: "It was genetically deformed material that embraced Islam. And now of course, with each successive generation it simply becomes concentrated. It gets worse and worse. It simply expresses itself and dictates their style of thinking, which is rooted in their genes. And through the centuries, the genes degraded further."
Stage five: Organisation
A plan to destroy Bosnia and "completely exterminate its Muslim people" was drawn up as early as the 1980s by the General Staff of the Yugoslav People's Army, according to Vladimir Srebrov, a politician who co-founded the SDS party with convicted Bosnian Serb war criminal Radovan Karadzic.
Known as the RAM (frame) plan, its aim was to carve up Bosnia into a Greater Serbia and a Greater Croatia.
In the plan, the officers explained how artillery, ammunition and military equipment would be stored in strategic locations in Croatia and Bosnia.
A secret police force was planned to arm and train local Serbs to create police and paramilitary units in Bosnia.
One document, written by the army's special services including experts in psychological warfare, stated the most effective way to create terror and panic among the Bosniak population would be by raping women, minors, and even children.
