The longsword is a European sword used during the medieval and Renaissance eras. Longswords are also sometimes called bastard swords, greatswords or hand-and-a-half swords. In addition to its length, its most important characteristic was your way to wield it. These weapons were used exclusively to two hands, and since its handle was “to hand and a half”, few of its forms could be made to use them with one hand.
The longsword was developed because plate armor replaced chainmail, so a longer and heavier sword was needed to penetrate the armor. This sword is used for striking, cutting and thrusting. This sword was not used as often in medieval combat, as the lighter swords were much easier to handle. These types of swords were heavily used back in the 13th-14th century, whereas using ending would be around 17th century.
The longest of these swords was the zweihander whose length was up to 6 feet. This sword was used by the landsknechts who came from the Holy Roman Empire or an area that is now modern-day Germany. These swords were also used to break up infantry formations by attacking pikes and halberds.
