Medieval Helmets: Types, Evolution, and Knight Armor Guide
Medieval helmets were one of the most important elements of medieval armor, protecting warriors from swords, arrows, axes, and blunt-force weapons. On the battlefield, a strong helmet often meant the difference between survival and death, which is why helmet construction improved steadily throughout the Middle Ages.
As weapons became more powerful and warfare more organized, armorers responded with increasingly sophisticated designs. Early helmets focused on basic skull protection, while later versions fully enclosed the head with steel plates engineered to deflect blows. From the early Spangenhelm to the heavily armored Great Helm, and later the versatile Bascinet and aerodynamic Sallet, helmet evolution mirrors the technological arms race of medieval warfare.
What Were Medieval Helmets?
Medieval helmets were protective headpieces worn by knights and soldiers throughout the Middle Ages to defend against swords, arrows, and blunt-force weapons. Evolving from simple iron caps to fully enclosed steel designs, these helmets balanced protection, visibility, and breathability while becoming defining symbols of medieval armor and battlefield survival.
In short, medieval helmets were essential defensive armor that evolved alongside weapons technology to improve a warrior’s chances of survival in combat.

The most recognizable design was the Spangenhelm, built from metal plates joined by riveted bands. Its conical shape helped deflect downward strikes.
High Medieval Period (11th–13th Century)
As heavy cavalry warfare expanded, knights demanded stronger facial protection.
- Rise of fully enclosed helmets
- Improved defense against direct blows
- Essential for mounted combat
The answer was the Great Helm — a helmet strongly associated with crusading knights. While highly protective, it restricted airflow and visibility, forcing warriors to balance defense with endurance.
Late Medieval Period (14th–15th Century)
Helmet engineering reached new levels of sophistication as armorers refined both safety and usability.
- Introduction of visors and ventilation
- Steel surfaces shaped to glance away blows
- Increasing specialization by battlefield role
During this period, the Bascinet became one of the most widely used combat helmets before eventually giving way to the highly refined Sallet throughout much of Europe.
Overall, medieval helmet design progressed from practical early protection to fully enclosed knightly armor, culminating in advanced late medieval helmets that combined survivability with improved battlefield awareness.
