le the sword remained a privilege, it was not so heavily confined to only the richest individuals, but rather to the richest classes.
The military importance of swordsmanship rapidly diminished with the advent of firearms. The last prominent battlefield sword to be used was the backsword. Although it was not a new invention, it managed to outlast other forms of war swords, being used by cavalry units and officers.
The power, accuracy, and reliability of firearms continued to improve, however, and soon swords had little place on the battlefield aside from ceremonial purposes. The preferred civilian dueling weapon shifted from the rapier to the faster but shorter smallsword, and eventually shifted totally away from swords to the pistol, following developments in firearm technology. The civilian affair of dueling was banned in most areas, but persisted to some degree regardless of law until well into the 20th century.
The German school of swordsmanship, in general, faced a decline during the Renaissance as the Italian and Spanish schools, which tilted more toward the rapier and civilian dueling, took the forefront. The compendium compiled by Paulus Hector Mair in the 1540s looks back to the preceding century of work and attempts to reconstruct and preserve a failing art. The treatise by Joachim Meyer, dating to the 1570s and notable for its scientific and complete approach to the style (it is suggested that Meyer's students came to him with less military knowledge and therefore required more basic instruction), is the last major account of the German school, and its context is now almost entirely sportive.
The use of the longsword continued to decline throughout the Renaissance period, marked by the increased effectiveness of the arquebus (a firearm) and the use of pike squares as a powerful implement of battle. During this time, civilian swords evolved to side-swords, also known as "cut and thrust" swords, and progressed towards the thicker, tapering sword that eventually became the 17th century rapier. This new weapon was popular for both protection on the street and as a tool in the duel, but found little success on the battlefield. The Italian, French, and Spanish schools embraced this change in civilian armament and developed systems of rapier fencing. The German school, however, provides little on this weapon and ceases its prevalence thereafter.
Development into a sport
The need to train swordsmen for combat in a nonlethal manner led fencing and swordsmanship to include a sport aspect from its beginnings, from before the medieval tournament right up to the modern age.
The shift towards fencing as a sport rather than as military training happened from the mid-18th century, and was led by Domenico Angelo, who established a fencing academy, Angelo's School of Arms, in Carlisle House, Soho, London in 1763. There, he taught the aristocracy the fashionable art of swordsmanship which they had previously had to go the continent to learn, and also set up a riding school in the former rear garden of the house. He was fencing instructor to the Royal Family. With the help of artist Gwyn Delin, he had an instruction book published in England in 1763 which had 25 engraved plates demonstrating classic positions from the old schools of fencing. His school was run by three generations of his family and dominated the art of European fencing for almost a century. 
He established the essential rules of posture and footwork that still govern modern sport fencing, although his attacking and parrying methods were still much different from current practice. Although he intended to prepare his students for real combat, he was the first fencing master yet to emphasize the health and sporting benefits of fencing more than its use as a killing art, particularly in his influential book 'L'École des armes (The School of Fencing), published in 1763. According to the Encyclopædia Britannica, "Angelo was the first to emphasize fencing as a means of developing health, poise, and grace. As a result of his insight and influence, fencing changed from an
