Step-by-step explanation:
Ashoka Maurya, also known as Ashoka the Great, was an emperor of the Maurya Dynasty. Ruling from approximately 268 to 232 BCE, he is renowned for his transformation from a ruthless conqueror to a benevolent ruler following the battle of Kalinga, which deeply affected him and led to his conversion to Buddhism.
Ashoka implemented many reforms, promoting peace, compassion, and welfare, through initiatives such as building hospitals, planting trees, digging wells, and establishing rest houses for travelers. He disseminated his teachings and edicts by erecting the Pillars of Ashoka across his empire, inscribed with messages of non-violence and ethical governance. These pillars also served to unite the empire and spread the influence of Buddhism, notably contributing to its prominence in regions like Sri Lanka.
