Alexander The Great

Alexander the Great was a king of the ancient Greek kingdom of Macedon who succeeded his father Philip II at the age of 20 and went on to create one of the largest empires in history by the age of 30. He was undefeated in battle and is widely considered to be one of history's greatest and most successful military commanders, conducting a lengthy military campaign throughout Western Asia, Central Asia, parts of South Asia, and Egypt. Alexander invaded the Achaemenid Persian Empire in 334 BC and broke its power in a series of decisive battles, eventually conquering the Achaemenid Empire and leaving a vast territory between the Adriatic Sea and the Indus River. After his death in 323 BC, a series of civil wars broke out across the Macedonian Empire, leading to its disintegration, but Alexander's legacy includes the cultural diffusion and syncretism that his conquests engendered, and he founded more than twenty cities, including the city of Alexandria in Egypt.learn more on wikipedia
