The Rome Statute is the result of multiple attempts for the creation of a supranational and international tribunal. At the end of the 19th century, the international community took the first steps towards the institution of permanent courts with supranational jurisdiction. With the Hague International Peace Conferences, representatives of the most powerful nations made an attempt to harmonize laws of war and to limit the use of technologically advanced weapons. After World War I and even more after the heinous crimes committed during World War II, it became a priority to prosecute individuals responsible for egregious crimes so serious that they needed to be exemplified by being referred to as "crimes against humanity". In order to re-affirm basic principles of democratic civilisation, the alleged criminals were not executed in public squares or sent to torture camps, but instead treated as criminals: with a regular trial, the right to defense and the presumption of innocence. The Nuremberg trials marked a crucial moment in legal history, and after that, some treaties that led to the drafting of the Rome Statute were signed.
