This documentary tracks the history of the longest-standing caliphate (Khilafat) of the contemporary world, which grew from dozens of devotees in a small village in India, into one of the largest Muslim communities in the world today. Following the passing of Hazrat Mirza Ghulam Ahmad^(as) in 1908, founder of the Ahmadiyya Muslim Jama’at, this documentary traces the establishment of his successorship (caliphate) and the brave Caliphs who continued his mission.
