Political organisation

Early Vedic Aryans were organised into tribes rather than kingdoms. The chief of a tribe was called a rajan. The autonomy of the rajan was restricted by the tribal councils called sabha and samiti. The two bodies were, in part, responsible for the governance of the tribe. The rajan could not accede to the throne without their approval. The distinction between the two bodies is not clear. Arthur Llewellyn Basham, a noted historian and indologist, theorises that sabha was a meeting of great men in the tribe, whereas, samiti was a meeting of all free tribesmen. Some tribes had no hereditary chiefs and were directly governed by the tribal councils. Rajan had a rudimentary court which was attended by courtiers (sabhasad) and chiefs of sects (gramani). The main responsibility of the rajan was to protect the tribe. He was aided by several functionaries, including the purohita (chaplain), the senani (army chief), dutas (envoys) and spash (spies). Purohita performed ceremonies and spells for success in war and prosperity in peace.

In the later Vedic period, the tribes had consolidated into small kingdoms, which had a capital and a rudimentary administrative system. To aid in governing these new states, the kings and their Brahmin priests arranged Vedic hymns into collections and developed a new set of rituals (the now orthodox Śrauta rituals) to strengthen the emerging social hierarchy. The rajan was seen as the custodian of social order and the protector of rashtra (polity). Hereditary kingship started emerging and competitions like chariot races, cattle raids, and games of dice, which previously decided who was worthy of becoming a king, became nominal. Rituals in this era exalted the status of the king over his people. He was occasionally referred to as samrat (supreme ruler). The rajan's increasing political power enabled him to gain greater control over the productive resources. The voluntary gift offering (bali) became compulsory tribute; however, there was no organised system of taxation. Sabha and samiti are still mentioned in later Vedic texts, though, with the increasing power of the king, their influence declined. By the end of the later Vedic age, different kinds of political systems such as monarchical states (rajya), oligarchical states (gana or sangha), and tribal principalities had emerged in India.

According to Michael Witzel 's analysis of the Kuru Kingdom, it can be characterized as the earliest Vedic "state", during the Middle Vedic Period. However, Robert Bellah observes that it is difficult to "pin down" whether the Kurus were a true "state" or a complex chiefdom, as the Kuru kings notably never adopted royal titles higher than "rājan," which means "chief" rather than "king" in the Vedic context. The Middle Vedic Period is also characterized by a lack of cities; Bellah compares this to early state formation in ancient Hawaii and "very early Egypt," which were "territorial states" rather than "city-states," and thus "it was the court, not the city, that provided the center, and the court was often peripatetic." Romila Thapar characterizes Vedic-era state formation as being in a condition of "arrested development," because local chiefs were relatively autonomous, and because surplus wealth that could have been directed towards state-building was instead used for the increasingly grandiose rituals that also served to structure social relations. The period of the Upanishads, the final phase of the Vedic era, was approximately contemporaneous with a new wave of state formations, linked to the beginning of urbanization in the Ganges Valley: along with the growth of population and trade networks, these social and economic changes put pressure on older ways of life, setting the stage for the Upanishads and the subsequent śramaṇa movements, and the end of the Vedic Period, which was followed by the Mahajanapada period.

According to George Erdosy, archaeological data for the period from 1000 to 600 BCE shows a two-tiered settlement pattern in the Ganges Valley, with some "modest central places," suggestive of the existence of simple chiefdoms, with the Kurukshetra district itself displaying a more complex (albeit not yet urbanized) three-tiered hierarchy. Subsequently, (after 600 BCE) there are four tiers of site sizes, including large towns and fortified cities, consistent with an urbanized state-level society.
