Emperor Samprati, the grandson and successor of Ashok, is poorly highlighted in history. He is regarded as the "Jain Ashok" for his patronage and efforts to spreading Jainism in east India. Samprati, according to Jain historians, is considered more powerful and famous than Ashok himself. The historical authenticity of Samprati is proved because Samprati Vihär, after the name of Samprati, existed at Vadamänu in the Krishna Valley during the second century A.D. Under the influence of Suhastin (the disciple of Acharya Sthulibhadra, the leading saint of the Jain community under Mahagiri, Samprati was again converted to Jainism, the Mauryas' ancestral religion. He spread Jainism by every means, working hard for Jainism as scriptures. He had decided to rinse his mouth in the morning, only after hearing that another new temple had been built. Besides, he got all the old and existing temples repaired and set up in all of them holy statues made of gold, stone, silver, brass and of a mixture of fine metals and performed their Anjankala ceremony: i.e., declared them fit for worship. It is said that Samprati built thousands of Jain Temples in India, many of which are still in use, such as the Jain temples at Viramgam and Palitana (Gujarat), Agar Malwa (Ujjain). Within three and a half years, he got one hundred and twenty-five thousand new temples built, thirty-six thousand repaired, twelve and a half million murtis, holy statues, consecrated and ninety-five thousand metal murtis prepared. Samprati is said to have erected Jain temples throughout his empire. He founded Jain monasteries even in non-Aryan territory, and almost all ancient Jain temples or monuments of unknown origin are popularly attributed to him. It may be noted that all the Jain monuments of Rajasthan and Gujarat, with unknown builders are also attributed to Emperor Samprati.
King Samprati had no children. He considered it the consequence of earlier Karma and observed the religious customs more scrupulously. After ruling over his large dominion for 53 years, he died in 179 BCE.
