Miletus (Ancient Greek: Μίλητος, romanised: Mílētos) was an influential ancient Greek city on the western coast of Anatolia, near the mouth of the Maeander River in present day Turkey. Renowned in antiquity for its wealth, maritime power, and extensive network of colonies, Miletus was a major center of trade, culture, and innovation from the Bronze Age through the Roman period. The city played a foundational role in the development of early Greek philosophy and science, serving as the home of the Milesian school with thinkers such as Thales, Anaximander, and Anaximenes.
Miletus's prosperity was closely linked to its strategic coastal location and the productivity of its surrounding rural hinterland, which supported thriving agriculture and facilitated wide-ranging commercial activity. The city established dozens of colonies around the Mediterranean and Black Sea, significantly shaping the Greek world’s expansion.
