The Battle of the Hydaspes was fought by Alexander the Great in 326 BC against King Porus of the Paurava kingdom on the banks of the river Hydaspes (now known as the Jhelum) in the Punjab near Bhera. The battle resulted in a complete Macedonian victory and the annexation of the Punjab, which lay beyond the far easternmost confines of the already absorbed Persian empire, into the Alexandrian Empire.
