What crime was Slobodan Milosevic tried by in international court?

Slobodan Milosevic, the former President of Serbia, was tried by the International Criminal Tribunal for the former Yugoslavia (ICTY) in The Hague, Netherlands. He was indicted on 66 counts of war crimes, genocide, and crimes against humanity. During the break-up of the former Yugoslavia and the ensuing war, Serbs in breakaway republics such as Croatia, Bosnia, and Kosovo carried out numerous atrocities, including the mass murder of civilians and forced deportations, also known as ethnic cleansing. Milosevic, as Serbian President, was held to be largely responsible for these outrages, both directly and indirectly. Specifically, he was accused of ordering, planning, preparing, and instigating these crimes.
The case against Milosevic dragged on at the ICTY for four long years. Even after all this time, the court still hadn't been able to get through the mountain of evidence offered by the prosecution. In any case, Milosevic died in his prison cell before any final judgment could be reached. Due to this unexpected development, the court was unable to render a verdict. But most historians and commentators believe that the charges brought against Milosevic were backed up by an overwhelming body of evidence, and that had he lived, he would certainly have been convicted on all counts of the indictment.
