After taking down the Seleucids, the Parthians established a huge empire in Iran and Mesopotamia. For over 400 years, they controlled the Silk Road and became Rome’s biggest competitor.
The Parthians, who rose to prominence around 247 BCE, turned into a major political and military force after defeating the Seleucids. At their peak, the Arsacid dynasty ruled an impressive area that stretched from the Euphrates River all the way to the Himalayas. Their grip on the Silk Road brought them massive wealth, allowing them to revive the glory of the Achaemenid Empire and embrace its diverse culture.
This wealth helped them create a top-notch army, famous for its skilled mounted archers and heavy cavalry. It’s no surprise that the Parthian Empire quickly became a superpower, the only ancient state capable of standing up to Rome. However, in a surprising turn of events, this powerful empire was nearly wiped from history by the rise of the Sassanian Empire.
Parthia Emerged Out From a Nomadic Tribe
Here’s a silver coin from Mithridates I, the Parthian king of kings. On one side, you see his head wearing a Hellenistic crown, and on the other, there’s a nude Hercules standing tall. This coin dates back to around 165–132 BCE and is part of The British Museum’s collection.
The Parthian Empire kicked off in 247 BCE when Arsaces I, who led a small nomadic group called the Parni, decided to invade the Seleucid Empire. Taking advantage of a local governor’s rebellion, he conquered the Parthia region, which became a key area for the new empire. The Arsacid rulers took advantage of the ongoing conflict between the Seleucids and Ptolemaic Egypt, expanding their territory both east and west. Their war with the Seleucids dragged on for years, allowing them to stretch their influence from the Euphrates all the way to Bactria, India, Central Asia, and even the Persian Gulf and Indian Ocean.
By the mid-second century BCE, the Parthians had taken control of all the main areas that were once part of the Achaemenid Empire, including the rich lands of Mesopotamia. It was here that King Mithridates I set up Ctesiphon, which eventually became the capital of the powerful Parthian Empire. The Parthian rulers started calling themselves shahanshah, meaning King of Kings, highlighting their connection to the legacy of the Achaemenids.
Parthia Was Famous for Its Military, Culture and Trade
The Parthian Empire, positioned perfectly at the crossroads of China, India, and the Eastern Mediterranean, became a major player in the Near East mainly because they controlled the Silk Road. This control not only boosted their economy through trade but also led to rich cultural exchanges, making their society diverse and prosperous. They developed a unique style in art and architecture that mixed Hellenistic, Persian, and local influences.
The ruling family, the Arsacids, showcased the empire’s inclusivity by initially using Greek as their official language, switching to Parthian only after tensions with Rome escalated. For centuries, Parthia was a strong rival to Rome, thanks to its vast wealth and a formidable military known for its skilled mounted warriors and the famous “Parthian shot” tactic. This strategy was later adopted by their successors, the Sassanids, as well as other nomadic groups from the Eurasian steppe like the Huns, Scythians, Mongols, and Magyars.
Parthia Controlled the Silk Road

The Parthian Empire was super important for the Silk Road trade, acting as a major link between the East and West. They controlled crucial parts of this trade route, which allowed silk, spices, and precious gems to flow, boosting their economy. Along with luxury goods, ideas like Buddhism also traveled through, influencing Parthian culture. You could see Indian art mixing with Parthian and Hellenistic styles, creating something really unique.
The Parthians were key players in connecting big ancient empires, like China and India in the East and Rome in the West. But their political and military strength made it tough for the Romans to get closer to the Eastern empires, especially China. To break the Parthian grip on the Silk Road, the Romans kicked off trade in the Indian Ocean, using ports in Egypt’s Red Sea as a launchpad for profitable maritime routes. Still, Rome and China never managed to connect directly.
Parthia and Rome Were the Greatest Rivals

So, the first time Rome and the Parthian Empire crossed paths was back in the early 1st century BCE during Rome’s conflict with Mithridates VI Eupator, the king of Pontus. In 92 BCE, they struck a deal that set the Euphrates River as the border between them. But that peace didn’t last long—things went south in 54 BCE when Roman general Marcus Licinius Crassus led his troops into Mesopotamia. The Romans quickly found out that Parthia was no pushover; they faced a crushing defeat at the Battle of Carrhae in 53 BCE. The Parthians used a clever hit-and-run tactic called the “Parthian shot” with their mounted archers, plus their heavy cavalry really gave the Romans a hard time.
Crassus didn’t make it out alive either, marking the start of many Roman leaders who would fall in the East instead of coming home as heroes. Although the Romans had some wins later on, especially under Augustus and Trajan, Parthia stayed Rome’s biggest rival right up until it fell in the early 3rd century.

Fall of Parthia Led to the Sassanid Empire

While Rome and Parthia were busy battling it out, they also sent envoys to each other, traded goods, and even teamed up sometimes, which showed they recognized each other’s strength. This tense situation went on until the early 3rd century when the Parthians, weakened by internal conflicts and their wars with Rome, fell to a new power. In 224 CE, Ardashir I revolted against the Parthian king, Artabanus IV, leading to the end of Parthia and the rise of the Sasanian Empire.
Unlike the Parthians, the Sassanians were always at odds with Rome. During the Crisis of the Third Century, the Parthians had a big win by defeating the Roman army at Edessa and capturing Emperor Valerian. The fighting in the East continued for about 400 years, with both sides having their ups and downs, until the early 7th century when Rome and Persia faced off in a brutal conflict known as the Last Great War of Antiquity.
In the end, the Romans came out on top but soon found themselves battling a new threat—the Arabs—just to stay afloat, while the Sassanids faded away as the last major ancient Iranian power.
