This volume contains writings on the 'Royal Period' (1626-1700), as distinguished from the 'Peshwa Period' of Maratha history, and added a long life of Malik Ambar (from original Persian sources) and biographies of four eminent Marathi historical research-pioneers, Rajwade, Sane, Khare and Parasnis.

The materials have come from Persian manuscripts (patiently gathered during a life-time), newly discovered Rajasthani despatches, Portuguese documents, French books, English factory records, and Marathi works brought to light only in the twentieth century, besides notes observed and heard during scores of visits to Maratha lands since 1907 by the author. Thus intimate personal information about Rajwade was secured at Dhulia where he died, and similarly about Parasnis at Satara and Poona.
