Final answer:
Mahmud of Ghazni was an invader and not responsible for the spread of Buddhism in India. Emperor Ashoka of the Maurya Dynasty was the one who, after converting to Buddhism, promoted its spread throughout India and across Asia through missionary work and by inscribing Buddhist teachings on pillars.
Step-by-step explanation:
Mahmud of Ghazni, a ruler primarily known for his invasions of the Indian subcontinent, did not directly contribute to the spread of Buddhism; this attribute is more closely associated with Emperor Ashoka of the Maurya Dynasty. Ashoka, after the battle of Kalinga, adopted Buddhism and promoted its principles across his empire and beyond. His rule marked a significant period in Indian history, known for the expansion of Buddhism through missionary work, and the inception of a law code that aimed to pr te harmony and compassionate governance. The great king Ashoka was responsible for disseminating Buddhism, as he constructed pillars inscribed with Buddhist teachings and sent Buddhist missionaries, including his son, to Sri Lanka to spread the faith.
Therefore, the influence of Mahmud of Ghazni on India is starkly different from the benevolent and cultural advancements attributed to Emperor Ashoka and the Mauryan Empire.
