The Persian king at the time of the Ionian Revolt (which began in 499 BCE) was Darius I, also known as Darius the Great. He ruled from 522 to 486 BCE and sought to consolidate and expand the Persian Empire.

Alexander was fortunate his soldiers refused to go east into India as he would have run into the overwhelming power of the expanding Mauryans and been exterminated.
