We're somewhere around 483 BCE, give or take a decade depending on who you ask. The Persian Empire is the largest political structure the ancient world had ever seen -- running from the Aegean coast in the west all the way to the borders of India in the east, with tens of millions of people spread across 127 provinces. Estimates of the empire's population vary widely in the scholarly literature, ranging from roughly 17 million on the low end to around 50 million on the high end, so the exact figure is genuinely uncertain -- but by any count, this is an enormous number of people under a single imperial authority. Its capital, Susa, is a place where the king's word is law, loyalty is everything, and a misstep in front of the wrong person can get you impaled on a stake. For Jewish exiles living here -- descendants of people deported from Judah by Nebuchadnezzar about a century earlier -- survival means learning this world's rules and deciding, often under real pressure, when to fit in and when to hold the line.
