Abu'l Fazl wrote the Ain-i-Akbari between the years 1589 and 1596. This Persian text served as the third volume of the larger Akbarnama and documented the administrative machinery of the Mughal Empire under Emperor Akbar.
The Ain-i-Akbari is divided into five books covering the imperial household, military and civil services, land revenue and judicial departments, social customs and literary traditions, and moral sentences. The first book Manzil-Abadi details 90 regulations regarding the court and household, while the second book Sipah-Abadi explains the Mansabdari System and military organization.
Raja Todar Mal organized the land revenue collection system known as Raja Todar Mal's Bandobast within the third book Mulk-Abadi. This system surveyed the land and established rent-rolls for the 15 Subhas or provinces of Akbar's empire to ensure fair and equitable revenue collection.
The original Persian text was translated into English in three volumes between 1873 and 1896. Heinrich Blochmann translated the first volume in 1873, while Col. Henry Sullivan Jarrett translated the second volume in 1891 and the third volume in 1896 for the Asiatic Society of Calcutta.
Sir Syed Ahmad Khan finished his scholarly edition of the text in 1855 and asked Mirza Asadullah Khan Ghalib to write a laudatory foreword. Ghalib instead wrote a short Persian poem criticizing the work and praising the English rulers, which caused Sir Syed Ahmad Khan to lose interest in history and archaeology.
