Year 2000 was a starting point for a major mobilization as it was the International Year for the Culture of Peace (UN Resolution A /RES/52/15): see IYCP Exhibition. On this special occasion, a global movement for a culture of peace was initiated by the United Nations to create a " grand alliance " of existing movements that unites all those already working for a culture of peace in its eight domains of action. This movement grew even more with the proclamation of the International Decade for a Culture of Peace and Non-violence for the Children of the World (2001-2010) (UN Resolution A /RES/53/25).

As Focal Point for the International Year for the Culture of Peace (UN Resolution E/1997/47 and lead agency for the Decade (UN Resolution A/55/47), UNESCO developed an interactive website allowing the actors of the movement to promote their initiatives and to exchange information and resources between each other for a better interaction. More than 75 million individuals and thousands of local, national and international organizations representing more than 160 countries are already part of it.

Various initiatives are being planned in Brazil in order to celebrate the closure of the Decade.
