Draft:History of Ray (Sasanian)

Tappe Mil (Bahram fire temple) in Rey, dating back to Sassanid Empire.

During the Sasanian period (224–651 CE), Ray was a well-fortified, densely-populated city with major military and strategic value. It helped fend off northern threats and carried out imperial campaigns. Ray’s religious role was long-standing and multi-layered, with Zoroastrian temples that looked after rituals and passed down sacred traditions. Archaeological finds have brought to light urban growth, pointing to Ray’s resource-rich lands and well-managed systems. The city was part of a network of Sasanian centers with shared architecture. Politically, Ray became a policy-driven, power-central hub where officials set up provincial control and carried out reforms. Its location linked it to cities like Ctesiphon, reinforcing imperial unity.

In the book Ancient Rey by Hossein Kariman, it is stated that during the Sasanian era, Rey was one of the major cities of Media or Jibal.

During the Sasanian period (224–651 CE), Ray became a densely-populated, military-centered city with strong architectural character. The Sasanians built up Ray as a strategic stronghold, putting up fire temples, barracks, and ceremonial halls across its semi-urban landscape. One of the most iconic structures was the Bahram Fire Temple at Tappe Mil, which stood out for its high-vaulted ceilings and thick-walled sanctuaries. Local craftsmen teamed up with imperial architects to carry out large-scale projects that reflected Zoroastrian ideology and state power. These buildings helped reinforce Ray’s role as a frontier city and spiritual center.

Strategic Role and Early Sasanian Importance

During the early Sasanian Empire (224–651), Ray stood out as a well-fortified and densely-populated city, located near present-day Tehran. The Sasanians built up Ray as a military stronghold to guard the empire’s northern frontier, especially against nomadic incursions from Central Asia. Historical and archaeological records show that Ray hosted a large military camp, which helped the empire fend off threats and carry out campaigns in the region. Its location at the crossroads of major trade and military routes made it a vital center for logistics and administration.

Tappe Mil

The Fire Temple of Rey (Tappe Mil) was the famous place of worship for Bahram Gur, the powerful Iranian king known for honoring Zoroastrian traditions and holding many celebrations. This temple is located about twelve kilometers southeast of present-day Rey.

Religious and Cultural Significance

Ray also played a long-standing and multi-layered role in the religious life of the Sasanian Empire. Zoroastrianism, the state religion, was deeply rooted in the city’s temples and fire sanctuaries. Priests and religious officials looked after sacred sites and passed down rituals that reinforced Sasanian ideology. The city’s religious institutions were closely tied to the central government, helping to unify the empire under a shared spiritual framework. Ray’s cultural influence extended into later Islamic literature, preserving its legacy as a sacred and scholarly center.

Urban Development and Archaeological Evidence

Archaeological surveys have brought to light a wide range of ceramic remains and settlement patterns that point to Ray’s urban growth during the Sasanian era. The city benefited from well-managed irrigation systems and resource-rich surroundings, which supported agriculture and sustained its population. Excavations reveal that Ray was part of a broader network of Sasanian urban centers, with shared architectural styles and material culture. These findings help historians reconstruct the city’s layout and understand its role in regional development.

Political Influence and Administrative Role

Ray’s political importance grew as the Sasanians set up provincial administrations and carried out reforms to strengthen control over distant territories. The city served as a power-central and policy-driven hub, where governors and officials coordinated tax collection, military recruitment, and legal affairs. Its strategic location allowed it to connect with other key cities like Ctesiphon and Nishapur, reinforcing the empire’s cohesion. Ray’s administrative role was crucial in maintaining order and projecting imperial authority across the Iranian plateau.

Strategic Crossroads

Main article: Military history of Rey, Iran

Ray, located near modern Tehran, was a strategically vital city during the Sasanian Empire (224–651 AD). Its fertile plains and proximity to the Alborz Mountains made it a well-connected base for military and administrative operations. The Sasanians set up long-term camps there to carry out troop musters and send reinforcements toward vulnerable frontiers, especially in the north and east. Ray’s water-rich landscape and road access helped cut down delays and shore up supply chains during wartime. As steppe and northeastern threats grew, Ray became a fallback zone where forces regrouped and pushed out again. Even though major battles with Rome and Byzantium happened farther west, Ray still played a key role in storing provisions and backing up multi-front coordination. Its fast-moving support helped hold the empire together during times of strain. In the late Sasanian period, internal collapse and external invasions wore down Ray’s defenses. Despite efforts to shore up the city, it couldn’t keep up with cascading defeats. However, its legacy as a war-tested, densely-settled center lived on into the early Islamic era. Archaeologists and historians continue to piece together Ray’s layered past, drawing on multi-lingual sources to build up a clearer, well-grounded narrative of its enduring importance.

Science

Sasanian science thrived through temple schools and courtly institutions that brought together Greek, Indian, and Iranian knowledge. Texts on medicine, astronomy, and philosophy were compiled and passed on, setting up knowledge flows that shaped later Islamic traditions.

Cheshmeh-Ali

In ancient times, the name of Cheshmeh Ali in the city of Rey was likely associated with the Sureni stream, probably named after the noble House of Suren, contemporaneous with the Parthian and Sasanian dynasties.
