Alexander the Great
A famous ancient king who conquered a huge empire.
Alexander the Great was a king and military commander who conquered much of the world known to people around the Mediterranean by age 30. Born in 356 BC in Macedonia (a kingdom north of ancient Greece), Alexander became king at 20 after his father was assassinated. Over the next 13 years, he led his army on an unprecedented campaign, conquering the massive Persian Empire and marching as far east as India, creating an empire that stretched from Greece to Egypt to the borders of India.
What made Alexander “great” wasn't just winning battles. He was a brilliant strategist who studied with the philosopher Aristotle as a boy and carried a copy of Homer's Iliad everywhere he went. He founded over 20 cities (many named Alexandria), spread Greek culture across three continents, and created connections between civilizations that had never really met before.
Alexander died suddenly at 32, possibly from illness, possibly from poisoning. His empire immediately broke apart as his generals fought over it. But the cultural mixing he started, blending Greek, Persian, Egyptian, and other traditions, lasted for centuries and changed world history.
