"I Will Kill Frick": Emma Goldman Recounts the Attempt to Assassinate the Chairman of the Carnegie S
Henry Clay Frick, chairman of the Carnegie Steel Company, was demonized by labor for his role in the violent Homestead strike in 1892 in which a pitched battle was fought between strikers and company-hired Pinkerton detectives. Known for his uncompromising and cruel tactics, Frick became an obvious target for labor activists looking to make a statement during the protracted strike.

"We Didn't Have Flies Until the White Man Came": A Yankton Sioux Remembers Life on the Plains in the
In the era before the U. S. Army conquered the Great Plains Indians the region's giant buffalo herds provided the primary food and clothing source for the Indians who lived there. Indeed, in 19th century America buffalo were more numerous than people. The various Lakota Sioux tribes who lived in the area that became South Dakota and Nebraska depended largely on the buffalo hunt according to Paul Picotte, a Yankton Sioux born in 1880. In this transcript of a 1968 interview with historian Joseph C

American Soldiers in the Philippines Write Home about the War
During the U.S. war in the Philippines between 1899 and 1904 (which grew out of the Spanish-American War that had erupted in 1898), ordinary American soldiers shared the nationalist zeal of their commanders and pursued the Filipino "enemy" with brutality and sometimes outright lawlessness. Racism, which flourished in the United States in this period, led American soldiers to repeatedly assert their desire "to get at the niggers." An anti-imperialist movement, which rejected annexation by the Uni
"Everything Was Lively": David Hickman Describes the Prosperity Late Nineteenth-Century Railroads Br
The availability of rail connections often determined whether a western community would survive or die. The rails fostered prosperity by bringing both goods and people. This trade, and the local service industries that sprouted up to capitalize on the movement of people and goods, drove many local economies. Here, David Hickman talked about the boom years that followed the arrival of the railroad in the Latah County, Idaho town of Genesee in the 1880s.
"Cast Down Your Bucket Where You Are": Booker T. Washington's Atlanta Compromise Speech
In 1895, Booker T. Washington gave what later came to be known as the Atlanta Compromise speech before the Cotton States and International Exposition in Atlanta.

"It Didn't Pan Out as We Thought It Was Going To"Amos Owen on the Indian Reorganization Act
The Indian Reorganization Act of 1934, which became known as the Indian New Deal, dramatically changed the federal government's Indian policy. Although John Collier, the commissioner of Indian affairs who was responsible for the new policy, may have viewed Indians with great sympathy, not all Native Americans viewed the Indian New Deal in equally positive terms. In this 1970 interview with historian Herbert T. Hoover, Amos Owen, Mdewakanton Sioux tribal chairman, gave a mixed verdict on the Indi
"We Ought to Have the Right to Belong to the Union": Frank Smith Speaks on the 1919 Steel Strike

"This is the United States," he argued, "and we ought to have the right to belong to the union."
"We Had to Be So Careful" A German Farmer's Recollections of Anti-German Sentiment in World War I
German Americans had a complex response to the attacks on their loyalty that emerged when the United States went to war against Germany in 1917. During and after the war, many German Americans began to conceal their ethnic identity--some changed their names; others stopped speaking German; still others quit German-American organizations. Many, like Frank Brocke, son of a German-American farmer, tried to keep a low profile. In this interview, Frank Brocke discussed his own assimilation (he later
