Inscription can be classified as monolingual, bilingual and trilingual and so on or as royal, official and private or religious and secular or as commemorative and donatives. Indian epigraphy of the medieval period covers mainly inscriptions for Arabic and Persian from Delhi Sultanate to later Mughal and British period.
Sultanate period’s inscriptions span by far the longest period of time from Shamsuddin Iltatmish, sultan of slave dynasty to Ibrahim lodi, sultans of Lodi, likewise among provincial kingdoms, from sultans of Malwa, to sultans of Gujarat, sultans of Bengal and Sarqi sultan of Jaunpur, Deccan kingdom such as Adil Shahi of Bijapur, Barid Shahi of Bidar, Qutub Shahi of Golconda, Nizam Shahi of Ahmadnagar, Imad Shahi of Berar were incorporated to the study of Indian epigraphy of medieval period, besides, Nawwab of Awadh, Nizam of Hyderabad, Nawwab of Murshidabad and sultans of Mysore, but to name a few.
Inscriptions present comprehensive picture of the past, in particular, local history of different village, town, cities and provenances of the province of imperial monarchy for which little references exist in the contemporary literary work. They also offer the ground information about the development of Language and Literature at the time of the imperial king when inscriptions were written. Epigraphs equally tell us about the evolution of sort of Arabic Persian script used at that time and space. Calligraphy is of the immense role in inscription which is instrumental in exhibiting the aesthetic contour of the edifices.
