In this thesis will be discussed about the reasons for the increase of Islamophobia in Hungary in 2015-2016. The theory that used to answer this problem is the theory of perception and the concept of non-traditional security threats. So there are two hypotheses from the answer to this problem, the first is the negative perception of the Hungarian government and society against the refugees who are predominantly Muslim and the second is the Hungarian government and society feel the risk of disruption of Hungarian national security by allowing Muslim refugees to live in Hungary . The bad perception that the Hungarian community and government have towards Islam is caused by several factors. The first is the historic Hungarian grudge caused by Mohacs War in 1546 which was won by Islam, the bad news of the western media about Islam, and also the terrorist case that happened in the name of Islam. This makes the Government very critical to receive Syrian refugees who want to go to Hungary and Europe because the majority of refugees are Muslims. It also worries the disruption of Hungary's national security by sticking to a bad image of Islam.
