Beginning with the Neolithic Chalcolithic phase to the introduction of iron technology in the Megalithic period and its consequent impact in the early historic times, this book examines the variations in iron making in peninsular India. Using archaeological data, where available, of the various regions of Andhra Pradesh (including Telengana), Karnataka, Tamil Nadu, and Kerala, a phase-wise analysis has been presented to highlight the material conditions of the various regions prior to, and after the introduction of iron technology, and to reflect changes in agricultural patterns, artisanal and structural activities and civilizational progress over time.
