The Islamic world in the Abbasid era

The Islamic world in the Abbasid era Author: Dr. Ahmed Ibrahim Al-Sharif Dr. Hassan Ahmed Mahmoud About the book: This book presents research on the roots of the Abbasid call and how it turned into a comprehensive revolution, how the Abbasid era was an application of its principles, and how this revolution left a deep impression on all aspects of the political, social, and cultural era. Then how this revolution opened the door for non-Arab Muslims to appear in all these fields. Then how the Abbasid Caliphate lost its effectiveness in the second Abbasid era due to the weakness of the Abbasid party in philosophy and organization, but the principles called for by the revolution continued to bear fruit despite the weakness of the caliphate. And it was no longer the history of the caliphate, but the Islamic peoples became the ones who made this history and its direction.
