The present work is a handy volume of all the available inscriptions so far known to us of the several minor ruling dynasties ruling in different sub-regions of early medieval Odisha roughly from the 8th to the 12th century CE. It has two sections: Section I: Introduction and Section II: Texts and Abstracts. In Section I, an analysis of the copper plate inscriptions of twenty minor ruling families have been included. The features of the copper plates and the royal seals attached to them have been narrated, and it also contained the script, language, and orthography of the inscribed texts. The genealogy and chronology of the ruling houses, the locality they held and the land grants they issued have been examined.
