Abstract-In this paper, the relationship between conflicts within OIC and historical development of Islamic state is studied in depth. By analyzing conflict databases that are divided into 4 periodical categories of Cold war and Decolonization, Post-Islamic Revolution, Fall of Berlin War and Soviet Empire, and Post 9/11 terrorism period, we found out the periodic phases significantly exacerbate the problem of Islamic diplomacy. We analyzed the intrinsic causes such as religion and corruption of Syria civil war and Iraq war to find out the reason for establishment of Islamic state, since IS primarily work in areas of Iraq and Syria. Through our statistical experiment, we showed that when both non-international armed conflicts (NIAC) and international armed conflicts (IAC) that involve states act in concert, the level of effective control a state has over its forces is the determining factor in whether the state can be said to be involved in an armed conflict. Using SPSS program, we calculated each frequency of conflicts that are divided into certain categories in order to show the broader perspective by using average N standard deviation. By quantifying the amount of variation or dispersion of a set of data values, we proved the firm connection between conflicts with high standard deviation and its foundation for Islamic states, thereby proving that historical conflicts within Islamic countries set the reason for the formation of Islamic state and better strategy of diplomacy and its religious makeup is needed.
