The Protocol was adopted by the United Nations in November 2000 as part of the United Nations Convention against Transnational Organized Crime. 

It is the first legally binding instrument with an internationally recognized definition of human trafficking. This definition provides a vital tool for the identification of victims, whether men, women or children, and for the detection of all forms of exploitation which constitute human trafficking. Countries that ratify this treaty must criminalize human trafficking and develop anti-trafficking laws in line with the Protocol’s legal provisions. 
They must provide protection and assistance to victims of human trafficking and ensure that their rights are fully respected. Find out how UNODC assists countries to implement the Protocol
