Rudravarman was a descendant of king Manorathavarman (Fàn Wéndí). His father was a brahman, while his mother was a niece of Manorathavarman. In 530 he was enfeoffed with titles king of Linyi (Linyi Wang 林邑王), Commissioner with Special Powers (Chijie 持節), Commander-in-Chief of all Military Affairs in the Coastal Region (Dudu Yanhai Zhujunshi 都督沿海諸軍事), General of Pacification of the South (Annan Jiangjun 安南將軍) by the Chinese Liang dynasty.[1][2]
In 541 he invaded the Jiude/Cửu Đức (Chinese: 九徳; pinyin: Jiǔdé; today Hà Tĩnh) province.[3] Pham Tu, a general of Ly Bon, defeated Rudravarman in 544. Michael Vickery speculates that Pham Tu might be a Linyi subject who then fled north and joined with Ly Bon.[4]
