The name sounds ancient. Almost mythic. It feels as if it belongs to scripture rather than shipping lanes.
So where did it come from?
To answer that, we must travel not just across water, but back through empire, language and faith.
THE PORT BEFORE THE STRAIT
Long before modern geopolitics turned the strait into a global flashpoint, there was a thriving port city called Hormuz. It sat on the southern coast of present-day Iran and later moved to an island nearby for security reasons.
Medieval travellers wrote about it with awe. Merchants from India, Persia and the Arab world docked there. It became one of the richest trading hubs in the region between the 13th and 16th centuries.
The waterway gradually took the name of the port. In other words, the strait was named after the city, and not the other way around.
But that only pushes the question further back. Where did the city of Hormuz get its name?
PERSIAN ROOTS, ZOROASTRIAN ECHOES
Most historians trace ‘Hormuz’ to the Middle Persian word ‘Hormoz’ or ‘Ahura Mazda’, the supreme deity in Zoroastrianism. Ahura Mazda was the central god of wisdom and light in ancient Persian belief.
Over centuries, the name evolved linguistically. ‘Hormoz’ became ‘Ormus’ in European records. Portuguese traders in the 16th century wrote it that way when they briefly controlled the island.
So is the name Persian or Zoroastrian?
The simplest answer is: both.
Zoroastrianism was the dominant religion of ancient Persia before Islam arrived in the 7th century. A divine name from that faith passed into place names. Those place names then travelled into trade maps and colonial charts.
By the time global powers began referring to the Strait of Hormuz in diplomatic cables, the name had already journeyed across languages and empires.
FROM SACRED WORD TO STRATEGIC CHOKEPOINT
Today, the Strait of Hormuz lies between Iran and Oman, linking the Persian Gulf to the Gulf of Oman and the Arabian Sea. Its geography makes it one of the world’s most watched maritime corridors.
Yet its name carries whispers of a much older world — one of fire temples, caravans and spice fleets.
The story of Hormuz is not simply about oil routes and naval patrols. It began with belief, moved through trade, and settled into maps. A Zoroastrian divine name flowed into Persian speech, then into a port city, and finally into the narrow waters that now shape global politics.
That is how a word born in ancient faith came to define one of the most powerful sea lanes on earth.
