• The increased agricultural activity and settled life led to the rise of sixteen Mahajanapadas (large territorial states) in north India in sixth century BC. The Buddhist literature Anguttara Nikaya gives a list of sixteen great kingdoms called ‘Sixteen Mahajanapadas’. 
• They were:

• The mahajanapadas are classified as ganasanghas and chiefdoms based on the nature of their polity.

Political Administration:

Gana-Sanghas

• The Vrijjis were one of the best known of the gana-sanghas, and Vaishali was their capital in the Mithila region. These kingdoms did not come under the single decision-making authority of a king but decisions were taken on a collective basis by the heads of the different clans together. There were also smaller kingdoms such as Kosala and Kasi.

Monarchies or Kingdoms

• The mahajanapadas on the Gangetic plains were all monarchies. Vedic orthodoxy was an established practice in these kingdoms. The priestly class enjoyed a preeminent status in the mahajanapadas unlike in the gana-sanghas. 
• The kingdoms were governed by kings and the administration was centralised. The brahman priests provided legitimacy to the king through various rituals. The kingship was hereditary and the succession was in most cases based on the law of primogeniture. The king was assisted by councils called parishad and sabha. The councils were advisory in nature. 
• The king appropriated the agricultural surplus through land revenue apart from a few other taxes. 

• Bali was a tax imposed based on the area of cultivable land. 
• Bhaga was obtained as a share of the produce. 
• Kara and Shulka were some of the other taxes collected during this period. 
• Thus the king raised revenue through taxes to maintain an elaborate administrative structure and an army. 

• The richer landowners were called grihapatis. These landowners employed labourers called dasas or karmakaras. The smaller landowners were known as kassakas or krishakas. 

Economy:

• Agriculture was the primary employment in the kingdoms.
• Trading and commerce thrived, with established trading routes.
• Kingdoms produced their own coinage to facilitate trade and commerce.
• Silver or copper coins were stamped with symbols and inscriptions reflecting the state’s political and cultural identity.
• These coins were referred to as punch-marked coins due to the punched symbols and dots on the metal.

Art & Architecture

• The Mahajanapadas developed a unique style of art and architecture.
• The kingdoms built impressive structures such as stupas, temples, and palaces.
• The art was characterized by intricate carvings and sculptures, which reflected the cultural and religious beliefs of the people.

Significance of the Mahajanpadas

• The Mahajanapadas signaled the beginning of the establishment of major territorial states in ancient India, governed by kings with clear administrative institutions.
• The growth of the Mahajanapadas also resulted in a move toward urbanisation. Many of these states’ capitals served as centers of trade, commerce, and culture.

• The Mahajanapadas saw the establishment of political alliances amongst numerous kingdoms. These alliances were formed for a variety of reasons, including mutual gain and countering foreign threats.
• Trade and commerce grew in importance when major territorial states emerged. The opening of new trade routes, as well as the development of roads and bridges, made it easier to exchange products and services.

• The Mahajanapadas had a significant effect on subsequent Indian history. Many of the political, social, and economic systems that arose during this time influenced Indian civilization for centuries to come.

State of Varna in the Society

• The society was stratified on the basis of varna. It emerged as a marker of status. Cultivators and artisans were identified as the shudras. A new social category that emerged during this period was placed below the shudras in the social hierarchy and considered untouchables. 
• They were forced to live on the fringes of the settlements and subsisted on hunting and gathering their food. 

• They were marginalised and given only menial jobs as urbanisation was on the rise. They had their own language, which was different from that spoken by the Indo-Aryans
