Why was the Ashoka called the great?

Ashoka, the third Mauryan emperor of India, is often referred to as "the Great" due to his significant contributions to the spread of Buddhism and his promotion of non-violence, tolerance, and ethical governance following the Kalinga War. His conversion to Buddhism led him to advocate for peace and welfare, resulting in numerous inscriptions that outlined his moral and social policies. Additionally, Ashoka's efforts in building infrastructure, including hospitals and roads, greatly improved the lives of his subjects and facilitated cultural exchange across his vast empire. His legacy as a ruler who prioritized the well-being of his people has cemented his status in history as a great leader.
