Great Railroad Strike of 1877:
A nationwide strike that took place from July 14 to September 4, 1877. More than 100,000 railroad workers were ultimately involved, and the strike affected such cities as Baltimore, Newark, Pittsburgh, St. Louis, and Chicago. The state National Guardsmen were often called in, but most militia members (and local residents) were sympathetic to the strikers. Ultimately, President Rutherford B. Hayes authorized the use of federal troops to break the strike. More than 100 workers were killed in the crackdown, and the strikers gained nothing. However, it led to more organized unionizing efforts.
Rutherford B. Hayes
 Nineteenth President. Served 1877–1881. While a Civil War veteran and a Republican, he ended Reconstruction as part of the Compromise of 1877 to resolve the disputed 1876 election. Enacted modest civil service reform. Ordered federal troops in to break up the Great Railroad Strike of 1877. Pledged not to run for reelection and returned to Ohio.
Scabs:
A type of strikebreaker. Specifically, someone who crosses a picket line of striking workers in order to take up a striking worker’s job.
Haymarket Square Riot:
On May 4, 1886, a rally in support of the eight-hour workday was held in Chicago’s Haymarket Square. When police began to break up what had been a peaceful public meeting, someone in the crowd threw a bomb at the police, and police fired into the crowd. Several dozens were killed. Rumors circulated that alleged the Knights of Labor were tried to the anarchist bombing, which fatally weakened the Knights. However, Haymarket Square ultimately became a global rallying point for the eight-hour workday. May Day began, in part, as an international commemoration for Haymarket Square.
American Federation of Labor:
 Founded in 1886, the AFL was a federation of 20 craft unions (unions of skilled workers, each representing a particular trade). The AFL concentrated on what they considered to be basic economic issues, such as the eight-hour workday and higher wages, rather than social change. Because the AFL was made up of skilled rather than unskilled laborers, their workers could not be as easily replaced by scabs if a strike were called. See: collective bargaining, closed shops, National Labor Relations Act.
Collective bargaining:
 The practice of negotiating between owners and a designation group of employees that represent all other employees. Contrast with: blacklisting, locking out, yellow-dog contract.
Homestead Strike:
A major strike in 1892 at the Carnegie Steel Company’s Homestead, Pennsylvania factory. After the workers went on strike, and the factory’s manager hired 300 private Pinkerton detectives to protect the plant and enable strikebreakers to enter and restart the steel operations. After an exchange of gunfire between the Pinkerton men and the workers, nine strikers and seven Pinkerton men were dead and many more people were wounded. Pennsylvania’s governor sent in 8,000 state militia to assist scabs to enter the mill. It was a major setback in unionizing the steel industry.
Turner’s “Frontier Thesis”:
An idea articulated by historian Frederick Jackson Turner in 1893. He argued that the frontier’s existence shaped the American character: a propensity for democracy, egalitarianism, individualism, and violence, as well as a disinterest in high culture. However, by 1890 the U.S. had no unsettled lands left. The Frontier Thesis partly reflects a then-budding romanticization of the American West, leading to the preservation of wilderness by conservationist and such things as the name for Kennedy’s “New Frontier” agenda.
Populist Party:
Also known as the People’s Party. Their 1892 policy platform advocated for a silver standard, a graduated income tax, direct election of U.S. senators, and ownership of railroads, telegraph, and telephone lines. While the Populists won five Western states in the 1892 election, the Democrats absorbed their policies thanks to William Jennings Bryan.
Interstate Commerce Act:
An 1887 law that which would regulate and investigate railroad companies that participated in interstate rail trafficking. The first example of the federal government regulating private industry in U.S. history. See: Interstate Commerce Commission.
Interstate Commerce Commission:
Authorized under the Interstate Commerce Act, the ICC originally investigated railroad companies in order to ensure fair rates. However, in its early years the ICC lacked enforcement powers. Farmers did not gain much from its formation, as they lost most of the cases brought before it. In later decades, the ICC also regulated other sectors of interstate commerce, such as busing, telegraphs, and telephones. Dissolved in 1996.
Battle of Little Bighorn:
Sometimes called Custer’s Last Stand, it is the most famous victory of American Indian forces over the U.S. military (although not the largest in death toll). The Sioux killed over 260 troops and their leader, Lt. Colonel George Armstrong Custer. The Sioux were hunted down and killed by other U.S. forces. See: Northwest Indian War, Blue Turtle.
George Custer:
 A Lt. Colonel who marched his column of men deep into Sioux territory only to discover some 2,500 Sioux warriors waiting for them at the Little Big Horn River. He and his men were then destroyed at the Battle of Little Bighorn—also known as Custer’s Last Stand.
Ghost Dance movement:
A Dakota Sioux movement that began in 1870. It intended to bring about a rebirth of native tradition and a repulsion of white incursion. As part of the U.S. government’s efforts to suppress it, the respected Sioux leader Sitting Bull, was killed.
Wounded Knee Massacre:
A massacre of over 200 American Indian men, women, and children that took place in December 1890 in South Dakota. Over 20 soldiers involved were awarded the Medal of Honor.
Dawes Severalty Act:
An 1887 act which stripped tribes of their official federal recognition and land rights and would only grant individual families land and citizenship in 25 years if they properly assimilated. Former reservation land was sold, and the proceeds funded “civilizing” ventures for natives, such as so-called Indian Schools which were rampant with abuse and neglect. This forced-assimilation policy remained the federal government’s way of dealing with American Indians until 1934.
