King Porus
When Alexander the Great defeated King Porus, he established two towns: one near the Jehlum River, and another near the Chenab River. The latter, present day Jalalpur Jattan was named "Shaklanagar", an amalgamation of Greek and Sanskrit words meaning "the city of beauty". These cities were settled by people from Alexander's multinational armies, which included a majority of Greeks. These Indo-Greek cities and their associated realms thrived long after Alexander's departure. Later, when Jalal ud din Firuz Khalji and his forces stayed here to suppress the invasion of Mongols, he renamed the city Jalalabad after himself. The name was once again changed to Jalalpur Jattan by the notable Jatts of their time, said to be Zabardast Khan and Ajmer Khan.
