Today, one of the most serious threats have engulfed a large portion of the Middle East is the emergence of the Sunni Muslim extremist group, known as ISIS (Daesh). After capturing a sizeable territory in Iraq and Syria, the group changed its name to Islamic State (IS). This text is geared towards discussing or describing the identification of ISIS in the age of globalization. ISIS at a limited national and regional level (compared to global level of Al-Qaeda) tries to build its identity via radical Islamic ideology, in a globalized world and identity crisis era. The weakening and in some cases breakdown of the political infrastructures such as Iraq and Syria often leads to a narrowing of identity and social solidarity away from national and towards sectarian, ethnic, and kin-based(however fictive) relations. In such a situation the dynamics of identity construction shift away from "project" towards "resistance" identities . If we take to account fundamentalist as a response to the identity crisis and also a solution to save its believers against the unsatisfied conditions of modern age, ISIS extended its ideology well through the region via protest against the unsatisfied conditions of the region. Findings of the research show that beside the similarities between ISIS and other Islamic extremist groups such as emphasizing on salafi ideology, work for founding Islamic Emirate or Caliphate based on Sharia law, extremist interpretations of Islamic religion, Jihadist and Takfiri vision, and believing in suicide tactics and dying for victory, ISIS's main goal is Jihad against Shiites (Near Enemy) and this may be the main difference between them that causes different kinds of behaviors. Other differences are different ideological roots, emphasizing on Jihad or Takfir by Al-Qaeda and ISIS respectively, giving priority to far enemy by Al-Qaeda and to near enemy by ISIS.
