A longsword (also spelled as long sword or long-sword) is a type of European sword characterized as having a cruciform hilt with a grip for primarily two-handed use (around 15 to 30 cm or 6 to 12 in), a straight double-edged blade of around 80 to 110 cm (31 to 43 in), and weighing approximately 1 to 1.5 kg (2 lb 3 oz to 3 lb 5 oz).
The "longsword" type exists in a morphological continuum with the medieval knightly sword and the Renaissance-era Zweihänder. It was prevalent during the late medieval and Renaissance periods (approximately 1150 to 1550), with early and late use reaching into the 11th and 17th centuries.
The Teutonic Order is a Catholic religious institution founded as a military society c. 1190 in Acre, Kingdom of Jerusalem. The Order of Brothers of the German House of Saint Mary in Jerusalem was formed to aid Christians on their pilgrimages to the Holy Land and to establish hospitals. Its members have commonly been known as the Teutonic Knights, having a small voluntary and mercenary military membership, serving as a crusading military order for the protection of Christians in the Holy Land and the Baltics during the Middle Ages.
