Uthama was known Vikrama Chozhan. and Madurantagan. Rajendra was also known as Vikrama Chozhan and Madurantagan!
This Vikrama ascended throne post Kulothunga I - 12th Century - ruled a brief spell of about ten years. The weblink posted gives more details of this King.
the contemprory chola of narasimha and his father was a minor king who comes in sivakaamiyin sabatham
his ticket to fame was that he was the father of mangayarkarasi and father in law of nedumaran the pandya king( both of them nayanmars).
vikrama solan of parthiban kanavu was a fictional charecter rising out of the creative churnings of kalki.
as others pointed out many of the major cholas were also called vikrama but I think there was one vikrama who was called exclusively by that name after kulothunga.
but I have a feeling think this discovery is going to stir the hornets nest again I CAN VISUALISE THE NEXT ISSUE OF VARALAARU:-))))
Vikrama Chola succeeded his father the famous Kulothunga Chola I to the Chola throne in 1120 C.E.
He was partially successful in regaining some of the territories lost by his father.
During his reign the Chola country suffered from severe floods and the resultant drought subsequently. Most of his provinces were affected.
Vikrama Chola was a great devotee of Siva and greatly patronised the temple at Chidambaram. In 1128 C.E. he signalled his devotion by allocating the entire revenue of the year to the upgrade and extension of the temple. He had the main Vimana of the temple and the roofs of the passages around the main deity covered with gold. He spent much of his time there.
The most characteristic title of Vikrama Chola was Tyagasamudra the ocean of sacrifice, which is found in his inscriptions and in Vikramacholan Ula.
