According to the Puranic lists of future kings, "137 years after the accession of Chandragupta Maurya, the Sungas will rule for 112 years and then the Kanvayanas for 45 years whose last king Susharman will be killed by the Andhra Simuka". If the accession of Chandragupta Maurya is dated to 324 BCE, then Simuka started to rule 294 years later, in 30 BCE.
