He married Anulā, wife of Khallātanāga, and adopted Mahācūlika as his own son; because of this Vaṭṭagāmaṇī came to be known as Pitirājā (this name occurs several times in the Commentaries — e.g., VibhA. passim, see Pitirājā).
Vaṭṭagāmaṇī had a second wife, Somadevī, and also a son of his own, called Coranāga. In the fifth month of his reign a brahmin, named Tissa, rose against him, but was defeated by seven Damiḷā who landed at Mahātittha. After that, the Damiḷā waged war against the king and defeated him at Kolambālaka.
