Context paragraphs:
Moody Sarno: Amerino J. "Moody" Sarno (September 21, 1914 – November 9, 1997) was an American football player and coach.  An All-American at Fordham University, he played on the same offensive line as future Pro Football Hall of Famer Vince Lombardi.  On March 30, 1941, he was hired as Boston College's line coach.  He became the Eagles head coach in 1943 after head coach Denny Myers joined the United States Navy.  Sarno himself was the only member of the Boston College coaching staff not to join the United States Armed Forces.  In three seasons as head coach at Boston College, he had an 11–7–1 record, including an unbeaten 1943 season.  He later served as head coach at his former school, Everett High School in Everett, Massachusetts, from 1955 to 1982.  In 28 seasons at Everett, he finished with a 128–116–11 record and won four state championships (1961, 1962, 1964, 1965).

C. Everett Koop: Charles Everett Koop, MD (October 14, 1916 – February 25, 2013) was an American pediatric surgeon and public health administrator.  He was a vice admiral in the Public Health Service Commissioned Corps, and served as the 13th Surgeon General of the United States under President Ronald Reagan from 1982 to 1989.  According to the Associated Press, "Koop was the only surgeon general to become a household name."

Coal Creek War: The Coal Creek War was an early 1890s armed labor uprising in the southeastern United States that took place primarily in Anderson County, Tennessee.  This labor conflict ignited during 1891 when coal mine owners in the Coal Creek watershed began to remove and replace their company-employed, private coal miners then on the payroll with convict laborers leased out by the Tennessee state prison system.

American Indian Wars: The American Indian Wars, Canadian Indian Wars or Indian Wars, were the multiple armed conflicts of European governments and colonists, and later American and Canadian settlers or the American and Canadian governments, against the native peoples of North America.  These conflicts occurred in the current boundaries of the United States and Canada from the time of earliest colonial settlements until 1924.  In many cases, wars resulted from competition for resources and land ownership as Europeans and later Americans and Canadians encroached onto territory which had been traditionally inhabited by Native Americans.  Warfare and raiding also took place as a result of conflicts between European governments and later the United States and Canada.  These governments enlisted Native Americans tribes to help them conduct warfare against each other's settlements and their Native American allies.

Armed yacht: An armed yacht was a yacht that was armed with weapons and was typically in the service of a navy.  Their speed and maneuverability made them useful as patrol vessels.  In the United States Navy armed yachts were typically private yachts expropriated for government use in times of war.  Armed yachts served as patrol vessels during the Spanish–American War and the World Wars.  In the latter conflicts, armed yachts were used as patrol vessels, convoy escorts, and in anti-submarine duties.  In the United States, yachts were purchased from their owners with the owners given an option to repurchase their yacht at the close of hostilities.

Charles Everett Lively: Charles Everett Lively (1887–1962) was a private detective affiliated with the Baldwin-Felts Detective Agency.  He played an active role in the Coal Wars in Appalachia, and is chiefly remembered as one of the assassins of Police Chief Sid Hatfield.

Apache Wars: The Apache Wars were a series of armed conflicts between the United States Army and various Apache nations fought in the southwest between 1849 and 1886, though minor hostilities continued until as late as 1924.  The United States inherited conflicts between settlers and Apache groups when Mexico ceded territory after the Mexican–American War in 1846.  These conflicts continued as new United States citizens came into traditional Apache lands to raise livestock, crops and to mine minerals.

Johnson County War: The Johnson County War, also known as the War on Powder River and the Wyoming Range War, was a series of range conflicts that took place in Johnson County, Wyoming between 1889 and 1893.  The conflicts started when cattle companies ruthlessly persecuted supposed rustlers throughout the grazing lands of Wyoming.  As tensions swelled between the large established ranchers and the smaller settlers in the state, violence finally culminated in Powder River Country, when the ranchers hired armed gunmen to invade the county and wipe out or scare off the small settlers they were competing against.  When word came out of the gunmen's initial incursion in the territory, the small farmers and ranchers, as well as the state lawmen, formed a posse of 200 men to fight them, which led to a grueling stand-off.  The conflict ended when the United States Cavalry, on the orders of President Benjamin Harrison, relieved the two forces, although further conflicts persisted in the following months.

Human trafficking in Colombia: The country of Colombia is a major source for women and girls subjected to trafficking in persons, specifically forced prostitution in Latin America, the Caribbean, Western Europe, Asia, and North America, including the United States.  Within Colombia, some men are found in conditions of forced labor, but the forced prostitution of women and children from rural areas and urban areas remains a larger problem.  Individual cases of forced marriage – a risk factor for trafficking – involuntary domestic servitude, and forced begging have been reported.  Some children are subjected to forced labor in mines and quarries, in the agricultural sector or as domestic servants.  Groups at high risk for internal trafficking include displaced persons, poor women in rural areas, and relatives of members of criminal organizations.  Continued armed violence in Colombia has displaced many communities, making them vulnerable to human trafficking.  Guerillas and new illegal armed groups forcibly recruit children to join their ranks; the government estimates thousands of children are exploited under such conditions.  Members of gangs and organized criminal networks force their relatives and acquaintances, and displaced persons – typically women and children – into conditions of forced prostitution and forced labor, including forced work in the illegal drug trade.  Colombia also is a destination for foreign child sex tourists, particularly coastal cities such as Cartagena and Barranquilla.  Migrants from South America, Africa, and China transit Colombia en route to the United States and Europe; some may fall victim to traffickers.

Coal Wars: The Coal Wars, or the Coal Mine Wars, were a series of armed labor conflicts in the United States, roughly between 1890 and 1930.  Although they occurred mainly in the East, particularly in Appalachia, there was a significant amount of violence in Colorado after the turn of the century.
