Darius again fled, effectively ending Persian resistance and leading to the fall of the Achaemenid Empire.

Alexander founded the city of Alexandria on the Mediterranean coast of Egypt. He personally selected the site and oversaw the initial planning. Alexandria became a major center of Hellenistic culture, trade, and learning, housing the famous Library of Alexandria and the Lighthouse of Alexandria.

Alexander crossed the Indus River and defeated King Porus at the Battle of the Hydaspes. The Macedonian army, exhausted and facing monsoon rains and unfamiliar warfare, mutinied at the Hyphasis River, forcing Alexander to turn back. This campaign marked the easternmost extent of his conquests.

Yang Su was appointed Grand Chancellor (Shangshu Ling), the highest civil office in the Sui government. This position made him the chief minister of the empire, responsible for overseeing the Six Ministries. He held this office until his death in 606.

Yang Su died in 606 AD. Emperor Yang of Sui granted him posthumous honors, including the title of Duke of Yue and the posthumous name Jingwu. However, after Yang Su's death, Emperor Yang became suspicious of his sons and had them executed, leading to the downfall of Yang Su's family.
