The river Jhelum (called the Hydaspes by the ancient Greeks) is a river in Northern India and Eastern Pakistan. It is a tributary of the Indus River. The “Battle of the Hydaspes” was fought in 326 BCE between Alexander the Great and King Porus of the Paurava kingdom on the banks of the river. The Greeks were victorious, resulting in large areas of the Punjab being absorbed into the Alexandrian Empire and the opening of the Indian subcontinent to Greek political and cultural influences.
