EVOLUTION OF INDIAN ADMINISTRATION:
Indian 'Administration' traces its earliest known form to the tribal system which later emerges as a monarchical system. We gain a lot of knowledge about ancient Indian Administration from ancient religious and political treatises. In the early Vedic period there were many tribes who elected their own chiefs and he handled all their responsibilities and the administration of the tribes and the Sabha( Assembly of elders) and Samiti(Assembly of people) were the tribal assemblies. The chief protected the tribe but had no revenue system or hold over land thus wars were resorted to and the booty shared among the tribes.
The first form of the 'State' in India can be traced back to the times of Manu(original name Satyavrata) the first King and progenitor of mankind according to Hinduism.People were fed up with anarchy as there was no neutral judge/arbitrator in between to solve issues of society, and so they appointed Manu as King and paid service fees as taxes for looking after them and ensuring mutual benefit and justice to everyone in society owing to his wisdom and philosophical attitude & the King was divine and regarded as descended from God.
As per the Ramayana and Mahabharata/Later Vedic times it goes to portray the role of the King as the whole and sole of administration being helped by his principal officers who were the Purohit and Senani where the Purohit( Priest) wielded much more authority than the kshatriya(Warrior clan) kings. Other figures of administration were Treasurer,Steward,Spies and Messengers,Charioteer,Superintendent of Dices. This is also mentioned in the Manu Smriti and Sukra Niti.
No legal institutions were there and the custom of the country prevailed as the law and capital punishment was not practiced but trials took place where justice was delivered by the King in consultancy with the Priest and Elders at times. By the time Kautilya wrote the ArthaShastra the Indian Administrative system was well developed and the treatise of Kautilya gives a very first detailed account of the same
