A Caliphate is an Islamic State. In 2014, the group of Islamic State of Iraq and Syria (ISIS) has restored the Islamic Caliphate and named their leader, Abu Bakr al-Baghdadi, as a Caliph, to the prophet Muhammad in the early Islamic empire (John, E.L., 2018). Therefore, ISIS established the Caliphate in order to continue the prophecy of Muhammad from the seventh century. ISIS main objective of establishing Caliphate is to create a Muslim state that will conquer the world (Tim, L., 2015). To Muslims, it is a duty to always seek to establish a caliphate and they believed a Caliphate can only exist if it holds power and territory. This is what makes them psychologically binding to each other that anyone besides their group or against their group are their enemies and they need to eliminate them. Hence, ISIS seeks to fight for greater political, legitimacy and militant power. For instance, ISIS’ first goal is to assert control over Iraq and Syria. They succeeded in controlling Libya and present in many parts of the world such as Yemen, Afghanistan, the Sinai Peninsula in Egypt, Europe, Asia, and the United States (Tim, L., 2015). Through this, ISIS has been using their Caliphate propaganda to reach out to all Muslims around the world in order to bind them into one perspective. As this is a technology era, their propaganda is mostly based on the internet presence and its objective is to influence other Muslims and to recruit more members to the group. As an example, before the pedestrians attack in Barcelona, it is reported that the Islamic State’s online magazine published an article about advices on how to kill a large number of people using a special kind of truck. The authorities still figure out whether the lone wolves killers read the article but it seems that they followed the advices. As a result, ISIS’ propaganda machine seems to grow and influence significantly to the people around the world as they aims to recruit more supporters by publishing many videos and articles a day (Joby, W., 2015). This propaganda also influences them put their devotion only to their god. “Propaganda isn’t just one guy putting together a magazine or a pamphlet; it’s a form of strategic communication…” (Douglas, W., 2017).
