An emination ofthe events of this period should help us to narrow down these limits and to understandthe circumstances that led to the rise ofthe new kingdom. We have already pointed out the significance oftheinvasion of I4gha andofthe events of his regis inthe bistorl ofthe island !gha began his rule at Poloanaruva in 1215. It is agreed that he was still ruling there in 1236 when Par]cramabThu II ascended the throne at Dabadeiya But there has been some amount of difficulty in determining the date of his defeat andthe duration of his reign. The CUavaisa gives the length of his rule as twenty-one years In the Pjva1iya, too, it is generally given as twenty-one years, but in one version it appears as nineteen (ekunvisi) years It has 1.

It is not stated in our sources how gha met his death or how his reign came to an end. In the account of Parkramabhu's campaign against the Dami.a a2d Ker4a forces, it is claimed that the mercenaries were completely routed but no mention is made ofthe fate of ?gha What then happened to Igha 2 Did he die in 1236 or later 7 Was he defeated by the Sinhalese army or did he meet his death before the final debc1e2 These are questions to which our sources do not provide any definite answer. It has been suggested that ?gha's rule did not end in 1236, although the C1lavazsa andthe P1!jva1iya have allowed him only a reign of twenty-one years According to this view, ParkramabThu II, unlike his father,Vijayabhu III, proclaimed himself as the sole monarch ofCeylonin 1236. 1.
