There are a lot of gaps to be filled in Indian history. Indian history is recorded in Purana and Ithihasas, Ramayan and Mahabharata. This information is complimented, corroborated and supplemented in the Regional languages of India. As, among Regional languages of India, I am familiar with Tamil and it’s early literature, I am quoting from Tamil references. Tamil is dated 20,000 years, at the very least. This date is based on the underwater findings of the remains of Poompuhar.
Tamil land was ruled by Three Dynasties, Chera, Chola and Pandya from ancient times. Cholas trace their ancestry to Solar Dynasty, the Surya Vamsa of Ikshvaku and Sri Rama . First human Manu was from the South of Vindhya mountain, Dravida and he meditated near Madagascar, as evidenced in the Srimad Bhagavadham.
One of the three Dynasties, Pandyas ruled from Madurai, now in Tamil Nadu. One of their earlier rulers was Kulasekara Pandya.
Sri Krishna invaded the Pandya Kingdom and in the battle he killed Kulasekara Pandya.

Radha and Krishna.
Initial capital of Pandyans was Manavur, from where a king named Kulasekhara Pandyan ruled. Sangam literature started developing during this regime.
He was contemporary to Magadha king Jarasandha.This king Kulasekhara Pandyan was killed by Krishna. This incident is described in Mahabharata.
Lord Krishna broke open the gates of a Pandyan King Kulasekhara and killed him in a battle.( Mahabharata VII.11.398) and VIII.23.1016)
Kulasekhara is said to be as strong as a bull. He is apparently killed by Lord Krishna, but although his son wants to avenge his father’s death, he is dissuaded from doing so by his well wishers. Krishna also defeated Chola King.(Mahabharata VII.11.321).
Krishna slew king Kulasekhara Pandya by striking his breast against his, and moved down the Kalingas in battle (5:48).
The Cholas and the Pandyas were mentioned as vanquished by Krishna at (7:11).
The date of the war between Kulasekara Pandya and Krishna war, therefore, is between 3200 and 3100 BC.
Kulasekhara was succeeded by his son Malayadhwaja Pandyan.
Malayadhwaja was also called as Saragadhwaja as Pandyan flag had symbol of a Bow. Saranga (Bow) + Dhwaja (flag).
An inscription records that a Pandya king led the elephant force in the Mahabharata War on behalf of the Pandavas, and that early Pandyas translated the epic into Tamil.
Malayadhwaja fought from Pandavas side in Kurukshetra war.
Kulashekharan is said to be as strong as a bull. He is apparently killed by Lord Krishna, but although his son wants to avenge his father’s death, he is dissuaded from doing so by his well wishers.
One of the contemporaries of Jarasandha of the Brhadratha dynasty of Magadha is Jayatsena of Magadha. He takes part in the Kurukshetra War in the Mahabharata as one of the leaders on the side of Kauravas, along with Srutayus of Kalinga, Paundraka Vasudeva of Pundra, Karna of Anga, and Malayadwaja of the Pandyas. Bhagadatta of the Naraka kings is also involved in the war.
During the battle, Malayadwaja apparently wounds the mighty Dronacharya, the teacher of both the Pandavas and the Kauravas, and who fights on the side of the Kauravas. Malayadwaja goes further and takes on Drona’s son, Ashwathama, in a duel. https://www.historyfiles.co.uk/KingListsFarEast/IndiaPandyas.htm
Malayadwaja’s daughter is Meenakshi, after whom the famous temple of Meenakshi Amman is built in Madurai. The city of Madurai is built around this temple. After this, the Pandyas fall back into obscurity for seven centuries.
