The correct option is (a) 1 and 2 only.
Explanation
During the Mahajanapada period (c. 6th century BCE), the emergence of large territorial states coincided with the Second Urbanisation. Capital cities became centers of power and were often fortified with massive walls made of wood, brick, or stone to serve military and administrative functions.- Statement 1 is Correct: The primary motivation for constructing forts was defense. As Mahajanapadas frequently fought for supremacy, kings built high walls to protect their capital cities and subjects from attacks by rival rulers.
- Statement 2 is Correct: Fortification served as an instrument of state control. Enclosing the city within huge walls allowed the king to monitor the movement of people, enforce laws, and collect taxes more efficiently. It also acted as a demonstration of the king's power and resource mobilization capabilities.
- Statement 3 is Incorrect: The construction of such massive fortifications required immense resources, thousands of laborers, and detailed logistical planning. This scale of work necessitated centralized planning and organization by the state authority. It was not a voluntary, unplanned effort by citizens.
Key Takeaway: Fortification in the Mahajanapada era was a centrally planned state enterprise designed for military defense against external threats and administrative control over the internal population.
