The Strait of Hormuz stretches about 100 miles and narrows to roughly 20 miles at its tightest point, acting as the gateway between the Persian Gulf and the Arabian Sea. Its strategic position made it a focal point for early sailors, traders, and historians who recorded it in the language of their own cultures.
Over centuries the passage earned a variety of labels. Greek geographers placed it within the broader "Erythraean Sea" and noted a "narrow passage" leading to the Persian Gulf. Roman writers later called it the "Strait of the Persians," while medieval Arab scholars used the Arabic phrase "Mugharr al‑Hormuz" meaning "the narrow of Hormuz." Each name reflects the perspective of the culture that named it.
