Tehran municipality created in 1999 the neighborhood councils, literally called “neighborhood associations”. They are defined as voluntary, collaborative, non politic and nongovernmental associations. Their members are volunteers elected each four years by universal suffrage.

On one side, the neighborhood associations reproduce elements of the Iranian political context within their own organizations and within their relationship with other actors. In this perspective, they are institutions of the Islamic Republic of Iran: The religious temporality, the figure of the shahid, the importance of the mosque as a meeting place or the institution vocabulary are “figures" of the Republic we can observe at the neighborhood level. On the other side, the setting up of a competition with more open procedures has enabled new actors to access to this local arena.

This paper is based on a field research conducted in Tehran in many neighborhood councils since 2007 (participant observation, semi-structured interviews with the various stakeholders (City advisors, citizens, researchers, state representatives, religious field actors...).
