Introduction
The side sword, known in Italy as the Spada da Lato, marks a crucial turning point in European sword history. It forms the bridge between the robust, medieval arming sword and the elegant, slender rapier of the 17th century. As knights in the early Renaissance left their heavy armour in the cupboard more often, there arose a need for a sword that could be worn not only on the battlefield, but also in everyday life at the side for self-defense.
Evolution of Hand Protection
The most striking difference with older swords is the hilt. Because civilians and soldiers outside the battlefield didn't wear steel gloves (armour gloves), the hand was extremely vulnerable.
Weapon smiths therefore added the following elements:
Finger rings: To allow the index finger to hook over the crossguard for more control, without being cut off.
Knuckle guards: A metal arch that protected the knuckles.
Ricasso: An unhardened part of the blade just above the hilt, often protected by extra rings, to provide grip for the fingers.

The Spanish and Italian School
The side sword flourished in the Mediterranean. In Spain it was called the Espada Ropera (literally "cloak sword"), because it was part of everyday clothing (ropa).
Italy, however, was the center of fencing. The Bolognese School, with masters such as Achille Marozzo and Antonio Manciolino, wrote extensive manuals about this weapon. Their techniques were dynamic and made use of both the cutting edges and the point of the sword.
Use with the "Main Gauche"
In a duel, the side sword was rarely used alone. Fencers often wielded a second object in the left hand (Main Gauche) for defence or distraction:
The Parrying Dagger: To catch attacks from the opponent.
The Buckler: A small round shield (brocchiero).
The Cloak: Which was wrapped around the arm to dampen blows or thrown over the opponent's sword.
Military vs. Civilian Context
Unlike the later rapier, which was almost exclusively intended for thrusting in civilian duels, the side sword remained a formidable military weapon. Thanks to the sturdy, broad blade, a soldier could still deliver powerful cuts with it, which was essential in the chaos of a battlefield. Christopher Columbus allegedly carried a side sword during his landing in the New World in 1492.

Frequently Asked Questions (FAQ)
Is a side sword the same as a rapier?
Not quite. A side sword has a broader blade and is better suited for cutting. The rapier is longer, thinner and almost entirely focused on the thrust. You can think of the side sword as the "father" of the rapier.
Why do some blades have waves (Flamberge)?
These "flame-shaped" blades were mainly a fashion trend in the 16th century (Mannerism). Although people at the time thought the waves caused extra vibrations when parrying, they often served to impress during parades on side swords.
Can I train with a side sword?
Yes, within HEMA (Historical European Martial Arts), the side sword is a popular weapon. There is much training with the techniques of the Bolognese masters.
Summary
The side sword is the versatile successor to the medieval sword.
It introduced complex hand protection for use without gloves.
It was the favorite weapon of the Bolognese fencing school.
Due to the sturdy blade, unlike the rapier, it remained highly effective on the battlefield.
