The Zweihänder (t͡svaɪhɛndɐ, literally 'two-hander'), also Doppelhänder ('double-hander'), Beidhänder ('both-hander'), Bihänder or Bidenhänder, is a large two-handed sword primarily in use during the 16th century. Zweihänder swords developed from the longswords of the Late Middle Ages and became the hallmark weapon of the German Landsknechte from the time of Maximilian I (d. 1519) and during the Italian Wars of 1494–1559. The Goliath Fechtbuch (1510) shows an intermediate form between longsword and Zweihänder. These swords represent the final stage in the trend of increasing size that started in the 14th century. In its developed form, the Zweihänder acquired the characteristics of a polearm rather than a sword due to their large size and weight and therefore increased range and striking power. Consequently, it was not carried in a sheath but across the shoulder like a halberd. Due to their size and weight—typically at least long and with a mass/weight of over —Zweihänders require two hands, as the name implies; as such they require at least for the grip. Zweihänders above were confined to ceremonial use. Early Zweihänders were simply larger versions of longswords. Later examples had Parierhaken ("parrying hooks") at the top of the ricasso as well as side rings on the hilt. Swords continued to be made without one or both features. Some Zweihänders had wavy blades and were called Flammenschwert. The weapon is mostly associated with either Swiss or German mercenaries known as Landsknechte, and their wielders were known as Doppelsöldner. However, the Swiss outlawed their use, while the Landsknechte kept using them until much later. The Black Band of German mercenaries (active during the 1510s and 1520s) included 2,000 two-handed swordsmen in a total strength of 17,000 men. Zweihänder-wielders fought with and against pike formations. Soldiers trained in the use of the sword were granted the title of Meister des langen Schwertes (lit. Master of the Long Sword) by the Mark Brotherhood.
