Cairo - Established in 1998, the Arab Center for Research and Studies (ACRS) is an independent think tank to study movements of political Islam and political-cum-sociological phenomena. The ACRS mainly focuses on developing theories in order to monitor, analyze and explain actions of Islamist movements and groups, and by extension assist policy and decision makers in this regard. This area of specialization is the backbone of the ACRS. The center also concentrates on studying Islamist movements' ideologies, circles, thought patterns and internal, intra and international interactions and incarnations. The ACRS is par excellence a pioneer research center in Egypt and Arab world that pays much attention to deeply studying, better understanding and closely monitoring political Islamist movements at local, regional and international levels. The center has more than two million documents that represent large and valuable databases of different strains of political Islam worldwide.
