Many radical changes took place as a result of the transition between the early and later Vedic periods.
The later Vedic period began around 500 BCE. The transition between the two is marked by the emergence of fully developed agriculture throughout India as well as a sharp decline in cattle ranching.
There were also sudden changes in the size of kingdoms because of increases in long distance trade. The power of the singular ruler increased. Rulers gave themselves elaborate titles like “one ruler” or “ruler of the world” which reflects their great gains. Sacrifices, especially of horses, became more and more common. Coronations became larger and more ostentatious, and while all these changes were taking place the political power of the common people was severely curtailed.
