King Porus (from Puru, the Latinisation of the Greek Πῶρος - Pôros, ultimately from Sanskrit: पुरुषोत्तम Purushottama) was the King of Paurava, an ancient state within the territory of modern day Punjab, located between the Jhelum river and the Chenab river (in Greek, the Hydaspes and the Acesines) rivers in modern day Punjab, Pakistan, and later of dominions extending to the Beas (in Greek, the Hyphasis). Porus fought Alexander the Great in the Battle of the Hydaspes River in 326 BC (at the site of modern day Mong) and was defeated. He then served Alexander as a client king.
Dynastic background 
Theories based on etymology 
Battle of the Ten Kings (dāśarājñá) is a battle alluded to in Mandala 7 of the Rigveda (hymns 18, 33 and 83.4-8), the ancient Indian sacred collection of Vedic Sanskrit hymns. It is a battle between Aryans (Vedic Indians) (an "internecine war", as the 1911 Britannica puts it, as opposed to the more frequent accounts of Aryans fighting Dasyus). It took place as Puru tribes, allied with other tribes of the Punjab and guided by the royal sage Vishvamitra, oppose the Trtsu (Bharata) king Sudas in battle, but are defeated as was celebrated in a provocative hymn of Sudas' poet and priest Vasistha (RV 7.18) One scholar, Buddha Prakash, Professor of History and of Ancient Indian History, Culture and Archaeology, Director of the Institute of Indic Studies (1964); in his book Political and Social Movement in Ancient Punjab states:
The Purus settled between the Asikni and the Parusni, whence they launched their onslaught on the Bharatas, and after the initial rebuff in the Dasarajna War, soon regrouped and resumed their march on the Yamuna and the Sarasvati and subsequently merged with the Bharatas, Some of their off-shoots lingered on in the Punjab and one of their scions played a notable part in the events of the time at Alexander's invitation. They probably survived in the Punjab under the name of Puri, which is a sub-caste of the Kshatriyas.
Theories based on symbolism and location 
Ishwari Prashad and some other notable scholars of Indian History Congress believe that Porus was Shoorsaini. They argue that Porus' vanguard soldiers carried a banner of Herakles whom Megasthenes - who travelled to India after Porus had been supplanted by Chandragupta- explicitly identified with the Shoorsainis of Mathura. This Herakles of Megasthenes and Arrian has been identified by some scholars as Lord Krishna and by others as his elder brother Baldeva, who were both the ancestors and patron deities of Shoorsainis. Tod and other notable scholars (Iswhari Prashad et al.) following his lead found further support of this conclusion in the fact that a section of Shoorsainis were supposed to have migrated westwards to Punjab and modern Afghanistan from Mathura and Dvārakā, after Krishna's demise and had established new kingdoms there.
The capital of Porus is located between the rivers Jhellum and Chenab in Punjab. This location is also the home of the Punjabi Khatri or Kshatriyas in Sanskrit. A gotra or subcaste of Punjabi Khatris are called "Puri" after him. Most of Puris are Hindus or Sikhs and migrated to various parts of India after the partition in 1947. After hasty departure of Alexander from Punjab triggered by the reluctance of his troops to move forward in Punjab, King Porus was established as the sovereign for the West Punjab. Some historians blame conspiracy by Chanakya in poisoning Porus. His son reigned for a short period and was eventually succeeded by Chandragupta Maurya.
Porus and Harikulas (Yadus) opposed Alexander 
Puru dynasty was probably the regal abode of the Porus who opposed Alexander. Puru dynasty is generally understood to be that of the Pandavas. The Harikulas have been identified by some scholars as none other than the descendants of Yadu.
- The cause of the Ten-Kings battle was that the Ten tried to divert the river Parushni. This is a stretch of the modern Ravi which, however, changed its course several times. Diversion of the waters of the Indus system is still a cause for angry recriminations between India and Pakistan. The 'greasy-voiced' Purus, though enemies of Sudas, were not only Aryans but closely related to the Bharatas. Later tradition even makes the Bharatas a branch of the Purus. The same clan priests in the Rigveda impartially call down curses and blessings upon the Purus in diverse hymns, which shows that the differences between them and the Bharatas were not permanent. The quarrel was of another sort than that between Aryan and non-Aryan. The Purus remained in the Harappa region and expanded their rule over the Panjab in later times. It was they who put up the strongest fight against Alexander in 327 BC.

- According to Arrian, Diodorus, and Strabo, Megasthenes described an Indian tribe called Sourasenoi, who especially worshipped Herakles in their land, and this land had two cities, Methora and Kleisobora, and a navigable river, the Jobares. As was common in the ancient period, the Greeks sometimes described foreign gods in terms of their own divinities, and there is a little doubt that the Sourasenoi refers to the Shurasenas, a branch of the Yadu dynasty to which Krishna belonged; Herakles to Krishna, or Hari-Krishna: Mehtora to Mathura, where Krishna was born; Kleisobora to Krishnapura, meaning "the city of Krishna"; and the Jobares to the Yamuna, the famous river in the Krishna story. Quintus Curtius also mentions that when Alexander the Great confronted Porus, Porus's soldiers were carrying an image of Herakles in their vanguard.Krishna: a sourcebook, pp 5, Edwin Francis Bryant, Oxford University Press US, 2007

From Hasti issued several tribes, of which the Curu and Pandus were the most distinguished; while from Yadu, elder brother of Pooru, issued the Hericula, or " race of Heri," who erected the cities of Surpaora, Mathura, and Baldevd, on the Jumna."
