Iraq is one of the most important countries in the world that has received its share of terrorist acts by the terrorist organization the Islamic State of Iraq and al-Sham (ISIS), which has caused instability, especially during the period of ISIS's control of seven Iraqi provinces (2014-2017). This stage has caused a decline in the levels of human and economic development and its inconsistency with the capabilities and needs of the Iraqi population. Therefore, this study aims to investigate the hypothesis that there is a close relationship between the decline in development in Iraq and the brutal practices of ISIS that it committed during his period of control over many Iraqi cities and regions. This study used several methods in order to address and identify all aspects related to the subject, such as the inductive descriptive approach and the documentary approach. Likewise, government documents, data and statistics mentioned in the reports issued by research and studies centers, conferences, regional and international organizations concerned with the study of terrorism and development were hotspots for obtaining information. A study trying to formulate a new research vision aimed at highlighting the main dimensions of the terrorist ideology of ISIS in that period and its role in the decline of the individual's right to development. The study recently concluded that the terrorist organization ISIS has a negative impact on Development indicators in Iraq through its direct effects on human security and freedom and the threat it poses to their lives, as well as the indirect impact on people's capabilities to access health, education and decent living resources.
