Why did Asoka build stone pillars across his empire?

To encourage his subjects to live moral lives
To remind his subjects that he was in charge
To commemorate fallen soldiers, from the battle of Kalinga
To add decoration to the provinces

The correct answer is: To encourage his subjects to live moral lives.

Asoka, the Mauryan emperor, erected stone pillars across his empire as a means to spread his moral teachings and encourage his subjects to live virtuous lives. These pillars, known as Asoka pillars or Edicts of Asoka, were inscribed with edicts that promoted principles such as non-violence, truthfulness, tolerance, and charity. By displaying these teachings prominently in public spaces, Asoka intended to shape the behavior and values of his citizens.
