It includes the biographies of ten prominent reformers in the modern era, chosen by the great thinker Ahmed Amin to be the subject of his book. Among them were: Jamal al-Din al-Afghani from the countries of Afghanistan, Muhammad Abduh, Ali Mubarak from Egypt, Sayyid Amir Ali and Sayyid Ahmed Khan from India, and others who were from the Hijaz, the Levant, and other countries.
Ahmed Amin's goal in publishing the biographies of these reformers was to awaken the enthusiasm of young people to follow in their footsteps and look to the future with optimism and will.
