The study concerns the armed Shiism in Iraq and its most prominent embodiment, the Mahdi Army (MA). It deals with the relationship between the MA and the Sadrist movement, as a case og the relationship between political organizations and their armed wings. It explores the specificity of this relationship, whereby the MA arose within the Najaf Shiite's Hawza . Hence, the  MA was not a typical armed wing, but was more like a general beacon of mobilization for the Shiite community in Iraq. MA was the first organizational step for the movement as much as its presence as the armed wing remained an essential pillar, controlling and determining the development of the movement. The study argues that the debate over the extent of armed action led to a struggle over the identity of the movement, between two wings: remaining an armed organization,  or turning to political action. Therefore, the leadership's efforts to control  MA were intersects with the political struggle between its wings.
