"That Broke Down the Ethnic Barriers": A Steelworker Describes the Decline of Ethnic Hostility in th
Tensions among industrial workers of different ethnic backgrounds often proved a barrier to unionization in the late nineteenth and early twentieth centuries. It was, for example, a key factor in the defeat of the 1919 steel strike. In the 1930s, however, that began to change, particularly under the auspices of the CIO. In this 1974 interview done by historian Peter Gotlieb in 1974, Polish-American steelworker Joe Rudiak recalled how ethnic hostility declined in the "CIO days," particularly amon
"Kill the Indian, and Save the Man": Capt. Richard C. Pratt on the Education of Native Americans
Beginning in 1887, the federal government attempted to "Americanize" Native Americans, largely through the education of Native youth. By 1900 thousands of Native Americans were studying at almost 150 boarding schools around the United States. The U.S. Training and Industrial School founded in 1879 at Carlisle Barracks, Pennsylvania, was the model for most of these schools. Boarding schools like Carlisle provided vocational and manual training and sought to systematically strip away tribal cultur

Croker and Fire Marshall William Beers commented on the safety lapses--the locking of an exit door, the inadequate fire escapes, and the overcrowded factory floor--that led to
"We Are Literally Slaves": An Early Twentieth-Century Black Nanny Sets the Record Straight
In folklore the black nursemaid was seen as a dutiful, self-sacrificing black woman who loved her white family and its children every bit as much as her own. Yet the popular images of the loyal, contented black nursemaid, or "mammy," were unfortunately far from the reality for the African-American women who worked in these homes. In 1912 the Independent printed this quasi-autobiographical account of servant life, as related by an African-American domestic worker, which dispelled the comforting "
