In the early Vedic period, the famous 'Battle of the Ten Kings' (Dasharajna) was fought on the banks of the river:

The "Battle of the Ten Kings" (Dasharajna), described in the seventh mandala of the Rigveda, was fought on the banks of the river Parushni, the present-day Ravi.

About the battle:

• It was fought between King Sudas of the Bharata tribe on one side, and a confederacy of ten kings (tribes) on the other.
• The ten tribes included the Purus, Yadus, Turvashas, Anus, Druhyus and others.
• Sudas won the battle, with the help of the god Indra, according to the Rigveda.
• The opposing forces are said to have drowned when they tried to cross the river.

Causes of the battle:

• According to the Rigveda, the sage Vishvamitra had been the priest of Sudas, but he was replaced by the sage Vasishtha.
• Vishvamitra then joined the rival tribes against Sudas.
• The battle may also reflect conflicts over land, cattle and the waters of the rivers.

Importance:

• It is one of the earliest recorded battles in Indian history.
• The victory of the Bharatas made them a dominant tribe in the region.
• Later, the Bharatas and the Purus came together to form the Kuru tribe, which became powerful in the later Vedic period.
• The name "Bharat" for India is linked with the Bharata tribe (or the legendary king Bharata).

Wars in the Rigveda:

• Conflicts were common, both between the Vedic tribes themselves and with other groups called "dasas" or "dasyus".
• War was called "gavishti" (search for cows), as many conflicts were over cattle.

About the Ravi:

• It rises in Himachal Pradesh and flows through Punjab into Pakistan, where it joins the Chenab.
• The Greeks called it "Hydraotes".

Why not the other options?

• ✗The Asikni (Chenab), Saraswati and Yamuna are other rivers of the Vedic region, but the battle took place on the Parushni.
