Welcome to the United Nations. It's your world.

Twelfth United Nations Congress
on Crime Prevention and Criminal Justice
Salvador, Brazil, 12-19 April 2010


For more than half a century, the United Nations has held congresses aimed at strengthening international cooperation against expanding crime.

The quinquennial congresses have impacted criminal justice policies, as well as national procedures and professional practices throughout the world. The congresses are especially critical now, as the globalization of many contemporary problems, including crime, has made international collaboration an urgent priority. The United Nations’ efforts to set international guidelines for criminal justice are not without precedent. In 1872, the International Prison Commission — which later became the International Penal and Penitentiary Commission (IPPC) — was created during an international conference to make recommendations for prison reform. The IPPC became affiliated with the League of Nations and continued to hold crime control conferences every five years.

With the dissolution of IPPC after World War II, its functions were transferred to the United Nations in 1950, including the practice of holding international conferences on crime control matters at five year intervals. Accordingly, the First United Nations Congress was held in Geneva in 1955.

Fifty-five years later, this tradition continues with the Government of Brazil hosting the Twelfth United Nations Congress in Salvador, Brazil. The theme of the Twelfth Congress is “Comprehensive strategies for global challenges: crime prevention and criminal justice systems and their development in a changing world”.
