The document summarizes the emergence of new dynasties and kingdoms in India during the 7th-12th centuries. Samantas, or warrior chiefs, gained power and wealth and declared themselves rulers, founding new dynasties like the Rashtrakutas. Men from noble families also established kingdoms through military conquests. These new kingdoms developed extensive administrative systems to collect taxes from across their territories to support their rule. Rulers competed for control of strategically important areas and wealthy temples through warfare. Powerful empires like the Cholas rose to prominence during this period and left lasting legacies through their large temple building programs and administrative innovations.
