Gandaraditya
Gandaraditha Chola (Tamil: கண்டராதித்ய சோழன்) succeeded his father Parantaka I and became the Chola king c. 955 CE.
Turbulent period
From the death of Parantaka I, to the accession of Rajaraja I in 985 CE, Chola history is obscure. During this period of 30 years there were five princes who must have occupied the throne. There are several theories surrounding the rapid ascension to the Chola throne.
One was that there were internal feuds among the different members of the royal family. The other is that the effects of the Rashtrakuta invasion, under Krishna III and his brother-in-law Ganga Butuga, and the defeat of the Chola army at Takkolam resulting in the death of heir-apparent Rajaditya Chola (the first in line to the throne - "aanai mael thunjiya devar") must have brought large-scale disorder in the kingdom.
The second theory has more merit since the sons of Parantaka I (specifically Gandaraditya and Arinjaya) must have also fought along with their brother, Rajaditya in that epic battle and must have been variously injured and died rapidly. Thus, Parantaka I was forced to get his grandson Sundara Chola (the son of Arinjaya and probably the oldest surviving prince) to be the heir-apparent.
