Ashoka was one of the most prominent emperors in India and successfully dominated the majority of the Indian subcontinent through conquest of military and maintenance of unity. Ashoka recently converted to Buddhism and saw the future of his empire in harmony and silence of his teachings. If Ashoka gathered so many wonderful people, the most difficult work had not yet arrived, and maintained peace between them. Ashoka's response to this difficult task was to invent and distribute various pledges to the people of the Mauryan empire.
Among the 16 Mahajanapadas, the Kingdom of Magdalen rises among several dynasties under Ashoka Maurya, one of India's most legendary and famous emperors. During the reign of Ashoka, Chola, Chera, Pandya dominated the south, King Devanampiya Tissa ruled the Kingdom of Anuradhapura (present Sri Lanka). These kingdoms do not belong to the Ashoka Empire, but they are friendly to the Maurya Empire. There was a strong alliance between Devanampiya Tissa (250-210 BC) and Ashoka in India, they sent Arahat Mahinda to four monks and sent beginners to Sri Lanka.
Chandragupta's son Bindusara ruled between 298 - 272 BC and expanded the empire during India. His son was great King Ashoka (born from 239 BC to 232 R was governed from 269 BC to 232 BC), under which his empire was very prosperous. Eight years after his reign, Ashoka conquered the eastern province Calinga and put out more than 100,000 dead. Shocked by destruction and death, Ashoka accepted the teachings of Buddha and started a systematic plan to argue Buddhist ideas and principles. He built many monasteries and generously contributed to the community of Buddhists. The enthusiastic support for his Buddhist values ultimately leads to financial and political pressure on the government, even his grandson Sampadi inherited the throne and opposed his policy. At the end of Ashoka's rule, the government's Ministry of Finance was severely exhausted through his normal religious contribution, after his death, the Empire declined immediately.
