The Greek geographer Herodotus (5th century BC) describes India, calling it ἡ Ἰνδική χώρη (Roman transliteration: hē Hindikē chōrē, meaning "the Indian land"), after Hinduš, the Old Persian name of the Indus river and the associated satrapy of Sindh in the Achaemenid Empire. Darius the Great had conquered this territory in 516 BC. The Greek colonies in Asia Minor (western Turkey) were already part of the Achaemenid Empre since 546 BC and, thus, the Greeks and Indians came into contact with each other as subjects of the Empire.[1]
