Porus or
Poros (from the
Greek Πῶρος,
Pôros) was a king of the
Pauravas whose territory spanned the region between the Hydaspes (
Jhelum) and Acesines (
Chenab) rivers in what is now
Punjab. Porus famously fought
Alexander the Great in the
Battle of the Hydaspes in 326 BC and it was generally believed by historians that he was defeated. Alexander was however greatly impressed by his adversary and not only reinstated him as a
satrap of his own kingdom but also granted him dominion over lands to the north extending until the Hyphasis (
Beas). After Alexander's death in 323 BC, Porus was assassinated by one of Alexander's generals named
Eudemus sometime between 321 and 315 BC.
