Why did ashoka the great write his edicts?

Ashoka the Great wrote his edicts to encourage his people to convert to Buddhism.

Explanation:

The Ashoka edicts are 33 edicts proclaimed by Emperor Ashoka and inscribed in caves, walls, rocks and the pillars of Ashoka, a series of columns scattered throughout their domains with the aim of bringing the content of these edicts to the entire population. Some pillars contain more than one edict, others are monographic and finally others do not retain the original text. The edicts explain parts of the life of its creator and his vision of the dharma, and constitute a key testimony of the history of Buddhism and customs of the third century BC.

The texts were dictated by Emperor Ashoka and distributed throughout the Indian subcontinent during his reign over the Maurya Empire since in 269 B.C. until 232 B.C. These inscriptions are the oldest historical documents in India that have been deciphered and the first to mention Buddhism. The edicts revolve around some recurring themes: the conversion of Ashoka to Buddhism, description of their efforts to spread this religion, their moral and religious precepts, as well as their social program.
