The Agency for Reincorporation and Normalization (ARN), formerly the Colombian Agency for Reintegration (ACR), was created on November 3, 2011 as a Special Administrative Unit – under the Administrative Department of the Presidency of the Republic (DAPRE) - responsible for strengthening the implementation of the Reintegration Policy.

The origins of the Agency date back to the Program for the Reincorporation of Civil Life (PRVC) that worked in the Ministry of Interior and Justice between 2003 and 2006.

The PRVC was characterized by psychosocial care, services and benefits for demobilized people. It was a short-term reintegration program. At first, this characteristic did not represent a problem, because the demobilized population was relatively small. However, when the rate of collective and individual demobilizations grew, the PRVC became congested and faced administrative, conceptual and operational difficulties.
