By 1840 the duels had diminished considerably; When the 7th Earl of Cardigan was acquitted of a statutory murder formality in a duel with one of his former officers, outrage was expressed in the media, with the Times claiming that there had been deliberate and high-level complicity in leaving the prosecution in a vacuum, reporting that «there is one law in England for the rich and another for the poor» and The Examiner on verdict as a «defeat of justice».   Duel culture survived in France, Italy and Latin America until the 20th century. After World War II, duels had become rare even in France, and those that still took place were treated as eccentricities in the press. Duels in France at that time were still taken seriously as a matter of honor, but not before death. They consisted of fighting with a sword, usually at a fixed distance, in order to draw blood from the opponent`s arm. In 1949, former Vichy civil servant Jean-Louis Tixier-Vignancour fought against teacher Roger Nordmann.  The last known duel in France took place in 1967, when Gaston Defferre insulted René Ribière in the French parliament and was later challenged to a duel with swords. René Ribière lost the duel after being injured twice.  In Uruguay, in 1971, there was a pistol duel between Danilo Sena and Enrique Erro, in which neither combatant was injured.   In most countries, duels were also used to decide impersonal matters.
In Spain, for example, a duel took place in 1085 to decide whether the Latin or Mozarabic rite should be used in the liturgy of Toledo: the Mozarabic master Ruiz de Mastanza won. The course of these duels was determined in great detail. They took place on closed fields, usually in the presence of the court and high legal and ecclesiastical dignitaries. Before the fight, each participant swore that his case was fair, that his testimony was true, and that he carried no weapons other than those prescribed and no magic tools. If one of the combatants was wounded or thrown, his opponent would usually put a knee on his chest and, if not called for clemency, drive a dagger through a joint of the armor. The tradition of the duel and the word duel itself were introduced to Russia in the 17th century by adventurers in the service of Russia. The duel soon became so popular – and the number of casualties among commanders so high – that Emperor Peter I was forced to ban the practice in 1715, otherwise he would leave the two duelists hanged. Despite this official prohibition, the duel became an important military tradition in the Russian Empire with a detailed unwritten duel code, which was finally written by V. Durasov and printed in 1908.
 This code prohibited duels between persons of different ranks. For example, an infantry captain could not challenge a major, but could easily use a titular advisor. On the other hand, a person of higher rank could not stoop to challenge lower ranks; It was therefore up to his subordinates or servants to take revenge on their master. And yet, the Coast Guard could still rain down on your parade.

Is there a place in the world where it is still legally possible to kill someone in a duel and not be charged? If not, when and where was the last place where this practice was banned? Mutual wrestling is also legal in Texas. As in Washington State, people who want to fight in Texas must do so under the watchful eye of a police officer. Given that Texas law allows people to carry swords in public, it`s hardly surprising that consensual fights are legal. In the 1770s, the practice of duel was increasingly attacked by many sections of enlightened society, as a violent relic of Europe`s medieval past unfit for modern life. As England began to industrialize and benefit from more effective urban planning and policing, the culture of street violence in general began to slowly decline. The growing middle class maintained its reputation either through allegations of defamation or through the rapid growth of the print media of the early 19th century, where it could defend its honor and resolve conflicts through correspondence in newspapers.
 The Washington State Mutual Struggle Act contains a provision that makes fighting a bit difficult legally: to be legal, a fight must be supervised by a police officer. Most of the time, police officers have something better to do with their time than watching a bunch of guys fight. In Ireland, until 1777, a code of conduct was drawn up to regulate duels between summer assizes in the town of Clonmel, County Tipperary. A copy of the code, known as «The Twenty-Six Commandments,» should be kept in a men`s pistol case for reference in the event of a procedural dispute.  William I introduced legal dueling to England in the 11th century; It was finally abolished in 1819. In France, deadly judicial duels became so frequent that attempts were made to reduce them from the 12th century onwards. The last, authorized by a French king, took place on July 10, 1547.  Research has associated fewer duels with increased government capacity.  Otto von Bismarck is said to have challenged Rudolf Virchow to a duel in the 1860s. Virchow, who had the right to choose weapons, chose two pork sausages, one of which was infected with the roundworm Trichinella; The two would each choose a sausage and eat. Bismarck reportedly refused.  However, the story could be apocryphal.
 Thank you for your question. No, not all duels ended in death. An example is this account of the duel between John Randolph and Henry Clay. blogs.weta.org/boundarystones/2013/09/04/guys-trying-get-themselves-killed-john-randolph-and-henry-clay The last fatal duel between Englishmen in England took place in 1845, when James Alexander Seton argued with Henry Hawkey over his wife`s affection, leading to a duel at Browndown at Gosport. However, the last fatal duel in England took place in 1852 between two French political refugees, Frédéric Cournet and Emmanuel Barthélemy, near Englefield Green; The first was killed.
