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 Crusades were a series of religious wars initiated, supported, and sometimes directed by the Latin Church in the medieval period. The best known of these military expeditions are those to the Holy Land in the period between 1095 and 1291 that were intended to conquer Jerusalem and its surrounding area from Muslim rule. Beginning with the First Crusade, which resulted in the conquest of Jerusalem in 1099, dozens of military campaigns were organised, providing a focal point of European history for centuries. Crusading declined rapidly after the 15th century.
In 1095, Pope Urban II proclaimed the first expedition at the Council of Clermont. He encouraged military support for Byzantine emperor Alexios I Komnenos against the Seljuk Turks and called for an armed pilgrimage to Jerusalem. Across all social strata in western Europe there was an enthusiastic response. Participants came from all over Europe and had a variety of motivations, including religious salvation, satisfying feudal obligations, opportunities for renown, and economic or political advantage. Later expeditions were conducted by generally more organized armies, sometimes led by a king. All were granted papal indulgences. Initial successes established four Crusader states: the County of Edessa; the Principality of Antioch; the Kingdom of Jerusalem; and the County of Tripoli. A European presence remained in the region in some form until the fall of Acre in 1291. After this, no further large military campaigns were organised.
