Francis Gladwin had a considerable reputation in his days as an accomplished Persian scholar and translator. After his valuable translation of Abul Fazl's Aini-i-Akbari, it encouraged him to persevere in his researches in the history of the successors of Akbar to attempt a delineation of the most material changes that happened in the constitution of Hindostan during the reign of Jahangir, Shah Jahan and Aurangzeb. Though he could not complete the project, this book, which is a fragment of it, is complete as far as the reign of Jahangir is con­cerned. It is a scholarly work based on a careful study of the original sources in Persian. Gladwin gives a short but essentially just estimate of?Jahangir's?character?and?attainments.
