Trigarta (also known as Jalandhara) was an ancient Indo-Aryan kingdom based in the region of modern day Punjab.

According to a genealogical record of the Kangra State, the first significant monarch is identified as Susarman, who is recognised for his participation in the Kurukshetra War based in the early Iron Age.

[2] Prior to the incursions by Muhammadan forces, Trigarta encompassed the territory situated between the Sutlej and Ravi rivers in the outer hills, extending to the Jalandhar Doab in the South, as outlined by J. Ph.

[2] The etymology of Trigarta has been understood to mean 'The land of the three rivers', referring to the Sutlej, Ravi and Beas in modern day Punjab.

These warriors had vowed to either die or kill Arjuna as part of a larger plan by Duryodhana to capture Yudhishthira alive.

Along with the Greeks, the following were mentioned as vratya kshatriyas or mlechhas: Dravida, Abhira, Sabara, Kirata, Malava, Sibi, Trigarta, and Yaudheya.

Hiuen Tsang visited Jalandhara in 635 A.D. and gave details that it was a country 1000 li (about 267 km) in breadth from north to south.

[15] The Trigarta capital was moved from Jalandhara to Nagarkot (Kangra) in 1070 A.D. due to constant contact in Jalandhar with various ambitious invading forces who usually were en route to central India.

[16] Ferishta mentioned another account of the 1st century A.D. when the king of Kanauj, Raja Ram Deo, went on conquest and overran the hills.
