Alexander the Great

"Philip's son, Alexander the Great (356–323 BC), managed to briefly extend Macedonian power not only over the central Greek city-states, but also to the Persian empire, including Egypt and lands as far east as the fringes of India. Alexander's adoption of the styles of government of the conquered territories was accompanied by the spread of Greek culture and learning through his vast empire. Although the empire fractured into multiple Hellenic regimes shortly after his death, his conquests left a lasting legacy, not least in the new Greek-speaking cities founded across Persia's western territories, heralding the Hellenistic period. In the partition of Alexander's empire among the Diadochi, Macedonia fell to the Antipatrid dynasty, which was overthrown by the Antigonid dynasty after only a few years, in 294 BC."
