was wounded and his force routed. When asked by Alexander how he wished to be treated, Porus replied "Treat me as a king would treat another king". Despite the apparently one-sided results, Alexander was impressed by Porus and chose to not depose him. Not only was his territory reinstated but also expanded with Alexander's forces annexing the territories of Glausaes, who ruled to the northeast of Porus' kingdom. After Alexander's death in 323 BCE, Perdiccas became the regent of his empire, and after Perdiccas's murder in 321 BCE, Antipater became the new regent. According to Diodorus, Antipater recognized Porus's authority over the territories along the Indus River. However, Eudemus, who had served as Alexander's satrap in the Punjab region, treacherously killed Porus. Eastern Punjab republics (c. 4th BCE - c. 4th CE) The Eastern Punjab republics, known as the Punjab Janapadas, were a group of republics during the ancient period of Punjab which were militaristic in nature, consisting of the Yaudheyas, Arjunayanas, Kunindas, Trigartas and the Audumbaras.

After the eventual fall of the Mauryans, the Indo-Greek Kingdom took its place in the Western Punjab. The Eastern Punjab supposedly wouldn't become subdued till the rule of Menander I, however there is little evidence of conflicts with the republics till after his death where the republics then begin to battle with his successors. The Trigartas producing their own coinage, the Yaudheyas and Arjunayanas winning "victory by the sword" and the Audumbaras under their ruler Dharagosha checking the indo Greek advance to the upper bari doab (ravi river) defining their control in the region. Two centuries after defeating the Indo-Greeks, the republics would become
