Simhavarman (Chế Năng)
Simhavarman, better known as Chế Năng, was a son of Chế Mân by the Javanese queen Tapasi and the last king of Champa's twelfth dynasty. After the Annamese captured his half-brother Chế Chí in 1312, the Trần court installed him as a vassal ruler.
He tried to recover the lost provinces of Ô and Lý. In 1318 Trần generals routed his army; Chế Năng fled to Java, opening the way for the Annamese-backed Chế A Nan.
