Alexander the Great
Alexander the Great (356-323 BCE) was King of Macedon who built one of the largest empires in ancient history, stretching from Greece to northwestern India, without ever losing a battle.
Alexander inherited the throne of Macedon at age 20 following the assassination of his father, Philip II, and quickly moved to expand the kingdom his father had built into an empire spanning three continents.
His campaigns took him through Egypt, where he founded the city of Alexandria, and across the Persian Empire, defeating King Darius III in several major battles, before pushing as far east as India.
Alexander died in Babylon in 323 BCE at just 32 years old, and his empire fractured among his generals shortly after. His conquests spread Greek culture across the ancient world in what is known as the Hellenistic period.
