Final answer:
Al-Biladuri was a contemporary historian who wrote to document the early Islamic conquests and to inform future generations about the past.
Step-by-step explanation:
Al-Biladuri was a contemporary historian, remembered for documenting the early Islamic conquests. His motivations for writing such historical works were likely informed by a desire to record the events and processes that shaped the Islamic world during his lifetime, as well as to provide a resource for future generations to understand their past. Although the background information mentions other historians such as Rashid al-Din and Ibn Khaldun, al-Biladuri's own work also made significant contributions to the field of historical scholarship during the medieval Islamic era.
