Bogotazo
El Bogotazo (from "Bogotá" and the ''-azo'' suffix of violent augmentation) was a massive outbreak of rioting after the assassination in Bogotá, Colombia of Liberal leader and presidential candidate Jorge Eliécer Gaitán on 9 April 1948 during the government of President Mariano Ospina Pérez. The 10-hour riot left much of downtown Bogotá destroyed. The aftershock of Gaitan's murder continued extending through the countryside and escalated a period of violence which had begun eighteen years before, in 1930, and was triggered by the fall of the conservative party from government and the rise of the liberals. The 1946 presidential elections brought the downfall of the liberals allowing conservative Mariano Ospina Pérez to win the presidency. The struggle for power between both again triggered a period in the history of Colombia known as '' La Violencia'' ("The Violence") that lasted until approximately 1958; the civil conflict that continues to this day originated from t ...

Streetcar
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term '' light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than main line and rapid transit trains. Most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city streets and diesel in more rural environments. Occasionally, trams also carry frei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molotov Cocktails
A Molotov cocktail (among several other names – ''see '') is a hand-thrown incendiary weapon consisting of a frangible container filled with flammable substances and equipped with a fuse (typically a glass bottle filled with flammable liquids sealed with a cloth wick). In use, the fuse attached to the container is lit and the weapon is thrown, shattering on impact. This ignites the flammable substances contained in the bottle and spreads flames as the fuel burns. Due to their relative ease of production, Molotov cocktails are typically improvised weapons. Their improvised usage spans criminals, gangsters, rioters, football hooligans, urban guerrillas, terrorists, irregular soldiers, freedom fighters, and even regular soldiers; usage in the latter case is often due to a shortage of equivalent military-issued munitions. Despite the weapon's improvised nature and uncertain quality, many modern militaries exercise the use of Molotov cocktails. However, Molotov cockta ...

Machete
A machete (; ) is a broad blade used either as an agricultural implement similar to an axe, or in combat like a long-bladed knife. The blade is typically long and usually under thick. In the Spanish language, the word is possibly a diminutive form of the word ''macho'', which was used to refer to sledgehammers. Alternatively, its origin may be ''makhaira, machaera'', the name given by the Greeks and Romans to the falcata. It is the origin of the English language equivalent term ''matchet'', though this is rarely used. In much of the English-speaking Caribbean, such as Jamaica, Barbados, Guyana, Grenada, and Trinidad and Tobago, the term ''cutlass'' is used for these agricultural tools. Uses Agriculture In various tropical and subtropical countries, the machete is frequently used to cut through rainforest undergrowth and for agricultural purposes (e.g. cutting sugar cane). Besides this, in Latin America a common use is for such household tasks as cutting large foodstu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, charcoal (which is mostly carbon), and potassium nitrate, potassium nitrate (saltpeter). The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building Pipeline transport, pipelines, tunnels, and road#Construction, roads. Gunpowder is classified as a Explosive#Low, low explosive because of its relatively slow decomposition rate, low ignition temperature and consequently low brisance, brisance (breaking/shattering). Low explosives deflagration, deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonation, detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamite
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay), and Stabilizer (chemistry), stabilizers. It was invented by the Swedish people, Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany, and was patented in 1867. It rapidly gained wide-scale use as a more robust alternative to the traditional gun powder, black powder explosives. It allows the use of nitroglycerine's favorable explosive properties while greatly reducing its risk of accidental detonation. History Dynamite was invented by Swedish chemist Alfred Nobel in 1866 and was the first safely manageable explosive stronger than black powder. Alfred Nobel's father, Immanuel Nobel, was an industrialist, engineer, and inventor. He built bridges and buildings in Stockholm and founded Sweden's first rubber factory. His construction work inspired him to research new methods of blasting rock that were more effective than black powder. After some bad business deals in S ...

Colombian Communist Party
The Colombian Communist Party (, PCC) is a legal communist party in Colombia. It was founded in 1930 as the Communist Party of Colombia, at which point it was the Colombian section of the Comintern. The party is led by Jaime Caycedo and publishes a weekly newspaper named ''Voz''. The Revolutionary Armed Forces of Colombia (FARC) was founded as the armed wing of the PCC in 1964, but the two organisations separated in 1993. History The Communist Party of Colombia was established in 1930 as the Colombian branch of the Comintern. The party pushed for improved conditions for Colombian laborers and an expansion of rights for the lower classes in Colombian society. Through the PCC, groups of laborers organized to combat the regulations and actions of the government and empowered corporations. These groups, known as "peasant leagues", established an interconnected network that coordinated protests and labor strikes, countered state-sanctioned violence, and sought to protect local ...

Mental Illness
A mental disorder, also referred to as a mental illness, a mental health condition, or a psychiatric disability, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning.

Juan Roa Sierra
Juan Roa Sierra (November 4, 1921 – April 9, 1948) was a Colombian known for assassinating Colombian Liberal leader and presidential candidate Jorge Eliécer Gaitán on April 9, 1948. After he shot Gaitán three times, mortally wounding him, a mob chased Roa Sierra down and killed him. The assassination of Gaitan triggered ''El Bogotazo'', riots that partially destroyed Bogota and led to ''La Violencia'', a period of violence that lasted until approximately 1958. A fictionalized account of his final days was presented in the 2013 feature film '' Roa''. Background Roa Sierra was the youngest child of Rafael Roa and Encarnación Sierra and had 13 siblings. In his book ''El Crimen del Siglo'' ("The Crime of the Century") writer and playwright Miguel Torres reports that Juan Roa Sierra was born in the neighbourhood “Egipto” (Egypt) in Bogotá, very near the humble residence where Jorge Eliécer Gaitán was born. His father was a stonemason and died from a respiratory illness, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
