Romans absolutely used spears, and they used them extensively throughout every period of their history. What makes Rome unusual among ancient civilizations isn’t the absence of spears but the variety of them. Roman armies deployed different spear types for different purposes: lightweight javelins for throwing, heavy thrusting spears for close combat, and long lances for cavalry charges. The specific designs evolved dramatically over roughly a thousand years of Roman military history.
The Pilum: Rome’s Signature Javelin
The weapon most associated with the Roman legionary is the pilum, a specialized throwing spear designed to be hurled at enemies just before close combat. Unlike a standard spear meant for stabbing, the pilum had a long, thin iron shank attached to a wooden shaft. This design gave it enough weight to punch through shields and armor, but the thin shank would bend on impact, making it impossible for enemies to pull out and throw back. Experimental archaeology by researchers Peter Connolly and Tod Todeschini confirms a maximum effective throwing range of about 25 to 30 meters, making it a close-range weapon used in the final seconds before soldiers drew their swords.
The pilum was standard legionary equipment from the middle Republic (around the 3rd century BC) through the height of the Empire. Soldiers typically carried two: one lighter version for longer range and a heavier one for maximum impact at close quarters. This combination of javelin volley followed by sword fighting became the signature Roman infantry tactic and distinguished legionaries from the spear-and-shield formations used by Greek and Macedonian armies.
The Hasta: A Traditional Thrusting Spear
Before the pilum became standard issue, and alongside it for centuries, Roman soldiers carried the hasta. This was a straightforward thrusting spear, roughly 2 meters (about 6.5 feet) long, similar in concept to the Greek dory. During the Roman Republic’s manipular system, the hasta was carried by the triarii, the third and final line of infantry in a Roman battle formation.
The triarii were the most experienced soldiers in the army. In the earliest periods they were also the wealthiest, since Roman soldiers supplied their own equipment, and high-quality spears, armor, and shields were expensive. By the time of the Second Punic War against Carthage in the late 3rd century BC, the army had shifted from sorting soldiers by wealth to sorting them by age and experience. The triarii remained the veterans, kept in reserve as a last resort. The expression “it has come to the triarii” became a Roman idiom meaning a situation had become desperate. Their role was to form a solid wall of spear points if the front lines of younger soldiers failed.
Auxiliary Troops and Their Spears
Roman legionaries were citizens, but a huge portion of Rome’s military consisted of auxiliary units recruited from conquered or allied peoples. These non-citizen soldiers frequently fought with spears as their primary weapon rather than the pilum-and-sword combination of the legions. Light spears served as throwing weapons for skirmishing troops, while heavier lances were standard equipment for auxiliary cavalry. This division of labor meant that across the Roman army as a whole, spears were probably more common than swords.
Auxiliary cavalry, in particular, relied on spears for mounted combat. Riders used lances for thrusting during charges, a role where the short legionary sword would have been nearly useless. As the Roman Empire expanded and incorporated more cavalry-heavy forces from the eastern provinces and the frontiers, spear-armed horsemen became an increasingly important part of Roman military power.
Late Roman Spears: The Spiculum and Contus
Around 250 AD, the Roman army underwent significant reorganization, and its weapons changed with it. The pilum was gradually replaced by the spiculum, a spear that worked both as a throwing javelin and as a thrusting weapon for hand-to-hand fighting. The spiculum retained some of the pilum’s penetrating power when thrown but was sturdier and more versatile in close combat. It remained in service until sometime after 400 AD.
The infantry also adopted a longer thrusting spear called the contus, with an ash wood shaft and either a leaf-shaped or pyramidal iron tip. Infantry versions ran about 8 feet long, while cavalry versions could reach up to 12 feet. Anything over 8 or 9 feet was generally too unwieldy for a soldier on foot. This shift toward longer spears reflected a broader change in late Roman tactics: as the traditional legionary fighting style built around the short sword faded, Roman infantry increasingly fought in formations that looked more like earlier Greek or later medieval spear walls.
Materials and Construction
Roman spear shafts were typically made from ash wood, prized for its combination of strength, flexibility, and light weight. Ash was the standard choice across many ancient cultures for the same reasons. The contus, for example, consistently used ash shafts. Spearheads were forged from iron, with shapes varying by purpose: broad leaf blades for cutting damage, narrow pyramidal points for punching through armor, and the distinctive long thin shanks of the pilum for its unique bending effect.
The quality of Roman spear manufacturing was closely tied to the army’s logistical system. State-run workshops called fabricae produced weapons in large quantities, ensuring a degree of standardization that most ancient armies lacked. This industrial approach to arms production meant Roman soldiers could reliably expect replacement weapons and consistent quality, a significant advantage in prolonged campaigns.
Why Romans Are Associated With Swords
If spears were so central to Roman warfare, why do most people picture a Roman soldier with a sword? The answer is partly about the Republic and early Empire, when the gladius (short sword) really was the legionary’s defining close-combat weapon. Roman tactical doctrine during this period emphasized throwing the pilum, then closing rapidly to fight at very short range where the gladius excelled. Writers like Polybius and Livy highlighted this aggressive sword-fighting style because it was distinctive, not because spears were absent.
The other factor is cultural emphasis. Roman military writers focused on citizen legionaries, whose pilum-and-gladius combination was seen as uniquely Roman. The thousands of auxiliary spearmen and cavalrymen who fought alongside them received far less attention in the sources. In reality, a Roman army on the march would have bristled with spears of every description, carried by auxiliaries, cavalry, and (in the later Empire) legionaries themselves.
