The term 'Panchajana' in the Rigvedic period refers to the "five tribes" commonly mentioned in the hymns. These tribes were:
Yadu
Turvasha
Anu
Druhya
Puru
These were considered the primary tribes or lineages mentioned repeatedly in the Rigveda.
The Bharatas were a sub-tribe or a clan of the Purus.
They rose to prominence later and are particularly noted in the Battle of Ten Kings (Dasharajna).
Although important in later Vedic literature and epics, they are not listed among the original Panchajana.
