Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH2CH2Cl)2, as well as other species. In the wider sense, compounds with the substituents −SCH2CH2X or −N(CH2CH2X)2 are known as sulfur mustards or nitrogen mustards, respectively, where X = Cl or Br. Such compounds are potent alkylating agents, which can interfere with several biological processes. Also known as mustard agents, this family of compounds comprises infamous cytotoxins and blister agents with a long history of use as chemical weapons. The name mustard gas is technically incorrect; the substances, when dispersed, are often not gases but a fine mist of liquid droplets. Sulfur mustards are viscous liquids at room temperature and have an odor resembling mustard plants, garlic, or horseradish, hence the name. When pure, they are colorless, but when used in impure forms, such as in warfare, they are usually yellow-brown. Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death.
The use of toxic chemicals as weapons dates back thousands of years, but the first large-scale use of chemical weapons was during World War I. They were primarily used to demoralize, injure, and kill entrenched defenders, against whom the indiscriminate and generally very slow-moving or static nature of gas clouds would be most effective. The types of weapons employed ranged from disabling chemicals, such as tear gas, to lethal agents like phosgene, chlorine, and mustard gas. These chemical weapons caused medical problems. This chemical warfare was a major component of the first global war and first total war of the 20th century. The killing capacity of gas was profound, with about 90,000 fatalities from a total of 1.3 million casualties caused by gas attacks. Gas was unlike most other weapons of the period because it was possible to develop countermeasures, such as gas masks. In the later stages of the war, as the use of gas increased, its overall effectiveness diminished. The widespread use of these agents of chemical warfare, and wartime advances in the composition of high explosives, gave rise to an occasionally expressed view of World War I as "the chemist's war" and also the era where weapons of mass destruction were created.
MoulayYusef ben Hassan, born in Meknes on 1882 and died in Fes in 1927, was the 'Alawi sultan of Morocco from 1912 to 1927. He was the son of Hassan I of Morocco, who was the son of Muhammad IV of Morocco.
Muhammad bin ‘Abd al-Karīm al-Khaṭābī, better known as Abd el-Krim, was a Moroccan political and military leader and the president of the Republic of the Rif. He and his brother M'Hammad led a large-scale revolt by a coalition of Riffian tribes against the Spanish and French Protectorates of the Rif and the rest of Morocco. His guerrilla tactics, which included the first-ever use of tunneling as a technique of modern warfare, directly influenced Ho Chi Minh, Mao Zedong and Che Guevara. He also became one of the major figures of Arab nationalism, which he actively supported.
The Battle of Annual was fought on 22 July 1921 at Annual, in northeastern Morocco, between the Spanish Army and Rifian Berbers during the Rif War. The Spanish suffered a major military defeat, which is almost always referred to by the Spanish as the Disaster of Annual which is widely considered to be the worst defeat suffered by the modern Spanish Army.
The Republic of the Rif was a confederate republic in the Rif, Morocco, that existed between 1921 and 1926. It was created in September 1921, when a coalition of Rifians led by Abd el-Krim revolted in the Rif War against the Spanish protectorate in Morocco. The French would intervene on the side of Spain in the later stages of the conflict. A protracted struggle for independence killed many Rifians and Spanish–French soldiers, and witnessed the use of chemical weapons by the Spanish army—their first widespread deployment since the end of the World War I. The eventual Spanish–French victory was owed to the technological and manpower advantages despite their lack of morale and coherence. Following the war's end, the Republic was ultimately dissolved in 1926.
The Rif or Riff, also called Rif Mountains, is a geographic region in northern Morocco. It is bordered on the north by the Mediterranean Sea and Spain and on the west by the Atlantic Ocean, and is the homeland of the Rifians and the Jebala people. This mountainous and fertile area is bordered by Cape Spartel and Tangier to the west, by Berkane and the Moulouya River to the east, by the Mediterranean to the north, and by the Ouergha River to the south. The Rif mountains are separated into the eastern Rif mountains and western Rif mountains.
Dámaso Berenguer y Fusté, 1st Count of Xauen was a Spanish general and politician. He served as Prime Minister during the last thirteen months of the reign of Alfonso XIII.
The Rif War was an armed conflict fought from 1921 to 1926 between Spain and the Berber tribes of the mountainous Rif region of northern Morocco.
The Ait Ouriaghel or Ait Waryaghar is one of the biggest Riffian tribes of the Rif region of the north-eastern part of Morocco and one of the most populous. Ait Waryagher means "those who do not back off/ those who do not retreat". They inhabit most of the territory around the city of Al Hoceima. The Ait Waryaghar speak the "Western-Tarifit" dialect of the Riffian language.
Hugo Gustav Adolf Stoltzenberg was a German chemist associated with the German government's clandestine chemical warfare activities in the early 1920s.
Rudibert Kunz is a German investigator, journalist and television editor.
Rolf-Dieter Müller is a German military historian and political scientist, who has served as Scientific Director of the German Armed Forces Military History Research Office since 1999. Rolf-Dieter Müller is also a former professor of military history at Humboldt University.
Riffians or Rifians are a Berber ethnic group originally from the Rif region of northeastern Morocco. Communities of Riffian immigrants are also found in southern Spain, Netherlands and Belgium as well as elsewhere in Western Europe. They are overwhelmingly Sunni Muslims, but retain their pre-Islamic traditions such as high status for Riffian women.
Francisco Gómez-Jordana y Sousa, 1st Count de Jordana, was a Spanish soldier and politician who served as Minister of Foreign Affairs during the rule of Francisco Franco.
There have been narrow-gauge railways which used 1,000 mm, 750 mm and 600 mm gauges.
The Alhucemas landing was a landing operation which took place on 8 September 1925 at Alhucemas by the Spanish Army and Navy and, in lesser numbers, an allied French naval and aerial contingent, that would put an end to the Rif War. It is considered the first amphibious landing in history involving the use of tanks and massive seaborne air support. Alhucemas is seen as a precursor of the Allied amphibious landings in World War II, and the first successful combined operation of the 20th century.
Chemical weapons have been a part of warfare in most societies for centuries. However, their usage has been extremely controversial since the 20th century.
The massacre of Monte Arruit took place on 9 August 1921 in Al Aaroui during the Rif War, when, after the July 1921 Battle of Annual, Riffian forces slaughtered most of the Spanish soldiers who had surrendered on that day.
Anarchism in Morocco has its roots in the federalism practiced by Amazigh communities in pre-colonial Morocco. During the Spanish Civil War, Moroccan nationalists formed connections with Spanish anarchists in an attempt to ignite a war of national liberation against Spanish colonialism, but this effort was not successful. Despite the brief establishment of an anarchist movement in post-war Morocco, the movement was suppressed by the newly independent government, before finally reemerging in the 21st century.
