In 256 AD, at the siege of Dura Europos, Roman soldiers entered a tunnel for a sneak attack—and encountered history's first recorded chemical weapon. This is the full story of the brutal clash between Rome and the Sassanid Empire. The siege was a key battle in the centuries-long Romano-Persian Wars. The city was a crucial Roman frontier fortress on the Euphrates, defended by the Cohors XX Palmyrenorum and legionary detachments. Its strong walls were tested by the besieging Sassanid army, leading to desperate tactics. This video explores the entire history of the siege, from the Roman defenses to the shocking archaeological discovery of the tunnel where Persian forces used toxic smoke from bitumen and sulfur to kill the Roman soldiers. We uncover the truth behind this ancient war crime and the fall of a Roman border stronghold. This is the World's FIRST Poison Gas

Or what the equivalent of a Legionary is today? In this video, we break down the chain of command, comparing the ranks of the world's most famous ancient military—the Roman Empire—with the modern structure of the United States Armed Forces. We'll see which ranks translate directly, which responsibilities have changed, and how the principles of leadership have stood the test of time.Roman Legions serving as foreign mercenaries??Historia Militum2025-09-23 | ...Did Roman Legions get SOFT? | The Late Roman Army ExplainedHistoria Militum2025-09-07 | What really happened to the Roman legions in the Late Roman Empire? Were they in decline, or did they simply adapt to survive new challenges? This video explores the transformation of the Roman army from the Principate to the 4th and 5th centuries, examining the evolution of Roman legions, auxiliaries, and cavalry into the Comitatenses and Limitanei. We’ll cover how Roman military equipment, tactics, and organization changed after the Crisis of the Third Century, why the creation of mobile field armies was necessary, and how the frontier defenses of the empire were structured. Along the way, we’ll bust the myth of a “declining” army and show how the Late Roman military remained disciplined, powerful, and capable of defending the empire against foreign invasions and civil wars alike. So How and Why did the Roman Legions change?

Not for emperors or generals — but for ordinary people. In the late 3rd century AD, as inflation spiraled out of control, Emperor Diocletian tried to fix the problem with one of the boldest economic experiments in history: the Edict on Maximum Prices. It failed — but it left behind an extraordinary record of everyday goods and services. In this video, we bring that list to life by stepping into the shoes of three very real Romans from different corners of society. Through their incomes, their meals, and the things they could (or couldn’t) afford, we’ll see how money, survival, and status were woven into daily life. Was life as a Roman soldier better than that of a provincial farmer? Could even the wealthy live well? And how do their struggles compare to ours today? Join us as we explore the Roman economy not through numbers on a page, but through the lived experiences of real people.Roman Legions that survived the Fall of Rome - Which Legion was the LAST?Historia Militum2025-08-17 | Support us on Patreon: patreon.com/HistoriaMilitum Our NEW YouTube channel: youtube.com/channel/UC1PiGi79snPk_qBH_VfCTsg?sub_confirmation=1
The Roman Empire may have fallen in 476 AD, but some legions lived on; their banners, traditions, and discipline unchanged. From the snowy frontiers of Gaul to the deserts of Palestine, they fought under the same names given to them by Caesar, Pompey, and Marc Antony. This video goes over the incredible stories of the last Roman legions to determine which one can be crowned the winner of the title of "the last Legion". This surprise legion served for 700 years, with 60 of its last soldiers choosing death over surrender. It’s a tale of survival, loyalty, and the end of a golden era.

The Dacian Wars rages on and its now time for Emperor Trajan to assemble the largest army Rome has ever brought to bear for an external campaign. The stage is set high up in the Carpathian Mountains, and Decebalus must fight for his life or face the subjugation of his people.The Roman Art of Combat | How ancient armies REALLY foughtHistoria Militum2025-07-26 | This video serves as part 2 of our series on reconstructing Roman combat, and dives into the mechanics of battle itself!

From the time of Julius Caesar, the Romans recognized the Dacian threat and vowed to one day subdue them. But with Caesar's assassination and continued internal civil wars and unrest, the Romans put off this campaign until 86 AD; all the while the Dacians have been growing in strength and number. Having delayed the campaign until now, the Romans looked on at the, by now, colossal challenge ahead of them: They are to scale the Carpathian mountains, enter the heart of the Dacian kingdom, and fight to the Dacian in their homeland and on their terms. To take on such an undertaking, the Romans will have to assemble the largest and most skilled army they have ever seen, and march them into the deep mysterious forests of Dacia, in what would be their largest challenge yet...

Some were hunters, others; engineers, armorers, bankers, stone masons, or craftsmen. Despite this very chaotic mess of different ranks and positions, we can develop a clear hierarchy of promotions that one had to follow in order to become a Centurion - The most respected officer position within each Century of 80 men.

This system was used during the Late Republic to bring the first Marian legions up to strength, and was practiced, in one form or another, in legions during the Late Empire, and even other nations during the Middle Ages.

But as a standing professional army, they were given large tasks of running the empire when not at war. In this video, we follow the 3rd Augusta legion, which was perhaps the legion with the least time fighting on the battlefield. It was stationed along the relatively peaceful African provinces, but this did not mean they sat idly. In fact, their enormous effort in countless civil tasks was so widespread, that the Provinces would likely not be able to function as efficiently without them. The 3rd legion serves as an example of just how important Roman legions were to the provinces they were stationed in, often taking up tasks like policing, tax collection, transportation, security, and even capturing animals for spectacles in the games!
