Step-by-step explanation:
Widely regarded as the greatest ruler in the history of India, Ashoka the Great is remembered for his contributions to the spread of Buddhism and his transformation into a compassionate ruler. After a brutal conquest of Kalinga that resulted in extensive death and suffering, Ashoka converted to Buddhism and embarked on a mission to promote harmonious and benevolent governance. His substantial role in propagating Buddhism beyond India, including missions to places like Sri Lanka, and his implementation of a new law code that provided protection for the vulnerable cemented his legacy as a revered figure.
