The "Mahavamsa" states that when Bindusara fell sick, Ashoka returned to Pataliputra from Ujjain, and gained control of the capital. After his father's death, Ashoka had his eldest brother killed, and ascended the throne. The text also states that Ashoka killed ninety-nine of his half-brothers, including Sumana. The "Dipavamsa" states that he killed a hundred of his brothers, and was crowned four years later. The "Vamsatthapakasini" adds that an Ajivika ascetic had predicted this massacre based on the interpretation of a dream of Ashoka's mother. According to these accounts, only Ashoka's uterine brother Tissa was spared. Other sources name the surviving brother Vitashoka, Vigatashoka, Sudatta (So-ta-to in "A-yi-uang-chuan"), or Sugatra (Siu-ka-tu-lu in "Fen-pie-kung-te-hun").
