The longsword is a straight, double-edged European sword built for two hands, with a grip long enough for both fists and a blade usually a metre or more long. It rose from the great war swords of the 13th century, matured around 1350–1500 as plate armour spread, and became the central weapon of the written fencing traditions of Germany and Italy.
The longsword is a straight, double-edged European sword designed for two hands, with a grip long enough for both fists and a blade usually a little over a metre. It is distinct from the one-handed arming sword: where the arming sword was carried with a shield, the longsword gave up the shield for reach, leverage, and two-handed control.
It emerged from the large war swords of the 13th century and matured between roughly 1350 and 1500, exactly as plate armour was replacing mail. That timing shaped it — the mature longsword had to both cut an unarmoured opponent and thrust into the gaps of a man in plate.
It was the weapon of knights and men-at-arms fighting on foot, and, just as importantly, of the civilian fencing guilds of Germany and Italy. The fight-books those masters left behind make the longsword one of the best-understood weapons of the Middle Ages.
"Longsword" is chiefly a modern classification. Medieval writers used shifting terms in several languages — the German Langes Schwert, the French espée de guerre or grant espée — without a single fixed technical vocabulary.
"Hand-and-a-half sword" describes the same physical idea: a grip that takes one hand comfortably and a second at need. "Bastard sword" is historically attested but was used loosely, and does not map neatly onto any one blade form.
These labels overlap rather than divide cleanly, so they should not be treated as precise, interchangeable categories. They name a family of related two-handed swords, not a set of standardised types.
Longsword fighting is preserved in unusual detail because fencing masters wrote and illustrated it. Their systems treat the sword as a lever and a probe, not a bludgeon: the fight is won by timing, leverage at the bind, and control of the opponent's point as much as by any single powerful blow.
The same weapon was used very differently depending on whether the enemy was armoured. Open, unarmoured fencing (Blossfechten) relied on cuts, thrusts and the play of the blades; armoured fencing (Harnischfechten) abandoned most cuts for the thrust and the half-sword.
Crucially, sword combat was never isolated from wrestling. A bind could become a throw, a disarm, or a dagger thrust, and the masters taught grappling as part of the same art. The cards below break down the main modes.
The German tradition descends from Johannes Liechtenauer, a 14th-century master whose teaching survives as a cryptic verse "Zettel" preserved and explained in later glosses and fight-books. Its core ideas — seizing the initiative (Vor), the master-cuts, winding at the bind, and feeling pressure through the blades — became the backbone of German longsword fencing.
The Italian tradition is best known through Fiore dei Liberi, whose Fior di Battaglia (c. 1409) lays out an integrated art of wrestling, dagger, sword in one and two hands, armoured combat, poleaxe, and mounted fighting. Fiore shows the longsword as one part of a whole martial education, not a stand-alone skill.
Together these traditions are why the longsword is so well understood today. They also anchor the weapon in a specific culture of trained fighters and fencing schools, well beyond the battlefield.
The longsword did not appear suddenly, and plate armour did not simply "create" it. It grew out of the high-medieval knightly sword through a gradual lengthening of blade and grip during the 13th and early 14th centuries, when big "war swords" could already be gripped in two hands.
As mail gave way to plate through the 14th century, blades diverged: some stayed broad for cutting, while stiff, sharply tapering forms developed for thrusting into armour. The mature hand-and-a-half sword of about 1350–1450 balanced these needs and coincided with the writing-down of the fencing systems.
The timeline below traces that progression. It runs on into the later 15th and 16th centuries, when the longsword flourished in the fencing guilds even as its battlefield role declined.
On the battlefield the longsword faded through the 16th century as massed pike and shot changed infantry warfare and lighter civilian swords took over personal defence. Its two-handed descendants, the great Zweihänder and montante, lingered as specialist weapons.
Its deepest legacy is documentary. Because masters like Liechtenauer, Fiore and later Hans Talhoffer and Paulus Kal recorded their art, the longsword is the anchor of the modern revival of historical European martial arts, reconstructed directly from period manuals.
That written record also corrects the popular picture. The medieval longsword of the sources is a fast, precise, versatile weapon used by trained fighters — not the clumsy heavy blade of later imagination.
