Memoir
A memoir (; , ) is any nonfiction narrative writing based in the author's personal memories. The assertions made in the work are thus understood to be factual. While memoir has historically been defined as a subcategory of biography or autobiography since the late 20th century, the genre is differentiated in form, presenting a narrowed focus. A biography or autobiography tells the story "of a life", while a memoir often tells the story of a particular event or time, such as touchstone moments and turning points from the author's life. The author of a memoir may be referred to as a memoirist or a memorialist. Early memoirs Memoirs have been written since the ancient times, as shown by Julius Caesar's ''Commentarii de Bello Gallico'', also known as ''Commentaries on the Gallic Wars''. In the work, Caesar describes the battles that took place during the nine years that he spent fighting local armies in the Gallic Wars. His second memoir, ''Commentarii de Bello Civili'' (or ''Com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lynching In The United States
Lynching was the widespread occurrence of extrajudicial killings which began in the United States' pre–Civil War South in the 1830s and ended during the civil rights movement in the 1950s and 1960s. Although the victims of lynchings were members of various ethnicities, after roughly 4 million enslaved African Americans were emancipated, they became the primary targets of white Southerners. Lynchings in the U.S. reached their height from the 1890s to the 1920s, and they primarily victimised ethnic minorities. Most of the lynchings occurred in the American South because the majority of African Americans lived there, but racially motivated lynchings also occurred in the Midwest and border states. Lynchings followed African Americans with the Great Migration () out of the American South, and were often perpetrated to enforce white supremacy and intimidate ethnic minorities along with other acts of racial terrorism. A significant number of lynching victims were accused ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johnson County War
The Johnson County War, also known as the War on Powder River and the Wyoming Range War, was a range conflict that took place in Johnson County, Wyoming from 1889 to 1893. The conflict began when cattle companies started ruthlessly persecuting alleged rustlers in the area, many of whom were settlers who competed with them for livestock, land and water rights. As violence swelled between the large established ranchers and the smaller settlers in the state, it culminated in the Powder River Country when the former hired gunmen to invade the county. The gunmen's initial incursion in the territory aroused the small farmers and ranchers, as well as the state lawmen, and they formed a posse of 200 men that led to a grueling stand-off. The siege ended when the United States Cavalry on the orders of President Benjamin Harrison relieved the two forces, although further fighting persisted in the following months. The events have since become a highly mythologized and symbolic story of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Range War
A range war or range conflict is a type of usually violent conflict, most commonly in the 19th and early 20th centuries in the American West. The subject of these conflicts was control of "open range", or range land freely used for cattle grazing, which gave the conflict its name. Typically they were disputes over water rights or grazing rights and cattle ownership. Range wars occurred prior to the Taylor Grazing Act of 1934, which regulated grazing allotments on public land. Range wars included the Pleasant Valley War, Colfax County War, Castaic Range War, San Elizario Salt War, Mason County War, Porum Range War, Johnson County War, Pecos War, Fence Cutting Wars, Sheep Wars, Barber–Mizell feud, Stuart's Stranglers conflict, and others. Range wars in literature and the arts Range wars have been the subject of movies and novels.

Tuberculosis
Tuberculosis (TB) is an infectious disease usually caused by '' Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with Latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active TB is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condom
A condom is a sheath-shaped barrier device used during sexual intercourse to reduce the probability of pregnancy or a sexually transmitted infection (STI). There are both male and female condoms. With proper use—and use at every act of intercourse—women whose partners use male condoms experience a 2% per-year pregnancy rate. With typical use the rate of pregnancy is 18% per-year. Their use greatly decreases the risk of gonorrhea, chlamydia, trichomoniasis, hepatitis B, and HIV/AIDS. To a lesser extent, they also protect against genital herpes, human papillomavirus (HPV), and syphilis. The male condom is rolled onto an erect penis before intercourse and works by forming a physical barrier which blocks semen from entering the body of a sexual partner. Male condoms are typically made from latex and, less commonly, from polyurethane, polyisoprene, or lamb intestine. Male condoms have the advantages of ease of use, ease of access, and few side effects. Individuals with late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
