What happened
Croesus, king of Lydia in western Anatolia and famous even in his own time for his wealth, saw Cyrus's growing power as both a threat and an opportunity. He asked the Oracle at Delphi whether he should attack Persia and was told that if he did, he would destroy a great empire, advice he took as encouragement without asking whose empire the oracle meant. Cyrus met Croesus's army on the plains north of the Lydian capital Sardis, and, according to Livius.org's account of the ancient sources, neutralized the feared Lydian cavalry by putting camels in the Persian front line, since horses that had never smelled the animals panicked and bolted. Cyrus then besieged the citadel of Sardis itself and took the city after a brief blockade. Ancient sources disagree on the precise year, with 547 or 546 BCE both defended by different scholars using the same Babylonian chronicle evidence.
Why it matters
Lydia's fall gave Cyrus control of the Aegean coast and its Greek cities, along with Lydia's mines and its innovation of minted coinage, which the Achaemenids would later adapt empire-wide. It was also the first time Cyrus took an old, wealthy, literate kingdom rather than a tribal confederation, a pattern he would repeat at Babylon a few years later.
How we know
Herodotus is the main narrative source, followed centuries later by other classical writers; a contemporary Babylonian text, the Nabonidus Chronicle, records Cyrus's activity in this period but its damaged text leaves the exact date of the Lydian campaign disputed among specialists.
