Why did the rajas of mahajanapadas build forts?

The rajas of Mahajanapadas constructed forts for strategic, defensive, and administrative purposes. Primarily, forts served as military strongholds, providing defense against external threats and invasions. Their strategic locations often overlooked key trade routes, enabling rajas to control commerce, exact tolls, and manage economic activities. These forts also functioned as administrative hubs, housing governance facilities, treasuries, and serving as symbols of the ruler’s authority. The construction of forts wasn’t just a military tactic but a manifestation of political power, reinforcing the legitimacy of the rajas. Additionally, forts provided refuge during times of conflict, ensuring the safety of the local population. In the dynamic and often turbulent landscape of ancient India, the building of forts was a multifaceted strategy to assert control, maintain order, and secure both the military and economic interests of the Mahajanapadas.
