Trtsu-Bharata were a royal family mentioned in Rigveda, their King Sudas defeated the 10 kingdoms in the battle of the 10 kings. This very battle was used to invent the fraud of Aryan invasion by colonial historians with vested interests.
that is just your bogus fake pride/nationalism and nothing else
you have only ''assumed'' that since kikatas were mentioned in rigveda which you assume to have been geographically confined to the punjab NW indian region, but nothing in the hymm itself indicates anything like that
Kikatas were never in southern punjab, always in Bihar, as has been confirmed by atharvaveda, mahabharatha, puranas etc.from rigveda to puranas, kikatas have been declared following nastika school of philosophy and not vedic philosophy which was predominantly the case during the historic periods itself.
the Kikatas are only mentioned in one RV hymn an it never states that there was any armed struggle between kikatas and the vedic tribes who have written this hymm or kikatas migrated and settled in east india.
if we go with the migrationist POV then obviously all the rigvedic and other post rigvedic tribes and kingdoms had their base in arctic circle, which is nothing but an argument based on bogus assumptions and zero evidences.
