For a little over 200 years, the First Persian Empire ruled over a vast expanse across three continents, making it arguably the world’s first great superpower. At its peak, it stretched from its base in Persia - roughly analogous to modern-day Iran, all the way to India in the East, incorporating swathes of Central Asia, Egypt, Libya and Iraq. It also conquered ancient powers such as Pharaonic Egypt, and the Neo-Babylonian Empire. Altogether, it ruled an area that now comprises some twenty nation-states.

But from where did it spring, and how did it establish such formidable power? Who were its leaders? And what led to its decline, completed with such ferocity by Alexander the Great?

This is a Short History Of… The First Persian Empire.
