325 BC
Year 325 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Camillus and Scaeva (or, less frequently, year 429 Ab urbe condita). The denomination 325 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Macedonian Empire
Alexander the Great leaves India and nominates his officer Peithon, son of Agenor, as the satrap of the region around the Indus.
Alexander the Great orders his admiral, Nearchus, to sail from the Hydaspes River in western India to the Persian Gulf and up the Euphrates River to Babylon while Alexander's army starts marching through Gedrosia (Baluchistan).
While returning to Persia, Alexander's army runs into the Malli clans (in modern day Multan). The ensuing battle severely weakens his army. Alexander sends much of his remaining army to Carmania (modern southern Iran) with his general Craterus, while he leads the rest of his forces back to Persia by the southern route through the Gedrosian Desert (now part of southern Iran and Makran in southern Pakistan).
