King Porus was the King of Paurava, an ancient state within the territory of modern day Punjab, Pakistan.  He fought Alexander the Great in the Battle of the Hydaspes River in 326 BC.  Alexander won the battle and the Punjab was annexed to his Empire.  The impressive resistance put up by King Porus and his men won Alexander’s respect – Alexander asked Porus to become a Macedonian satrap, following the latter’s surrender.
