Lydia (Ancient Greek: Λυδία, romanized: Ludía; Latin: Lȳdia) was an Iron Age kingdom situated in western Anatolia, in modern-day Turkey. Later, it became an important province of the Achaemenid Empire and then the Roman Empire. Its capital was Sardis.
At some point before 800 BCE, the Lydian people achieved some sort of political cohesion, and existed as an independent kingdom by the 600s BCE. At its greatest extent, during the 7th century BCE, it covered all of western Anatolia. In 546 BCE, it became a satrapy of the Achaemenid Empire, known as Sparda in Old Persian. In 133 BCE, it became part of the Roman province of Asia.
