Remembering the First Crusade: Latin Narrative Histories 1099-c.1300
The success of the First Crusade by the Christian armies caught the interest and arrested the imagination of contemporaries, stimulating the production of a large number of historical narratives. Four eyewitness accounts, as well as letters written by the crusaders to the West, were taken up by later authors, re-worked and re-fashioned into new narratives; a process which continued throughout the twelfth century and beyond. This thesis sets out to explore why contemporaries continued to write ab

No Way Out: Two New York City Firemen Testify about the 1911 Triangle Shirtwaist Fire
One of the greatest industrial tragedies in U.S. history occurred on March 26, 1911, when 146 workers, mostly young immigrant women, died in a fire at the Triangle Shirtwaist company in New York City. In this brief excerpt from their testimony before the Factory Investigation Commission, New York City Fire Chief Edward F. 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
"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. In this excerpt from her autobiography, Living my Life, radical Emma Goldman described how fellow radical Alexander
"We Sang Rock of Ages": Frances Willard Battles Alcohol in the late 19th century
Among the social movements joined and led by women in the late 19th century, including unionization and women's suffrage, none had either the widespread fervor or success enjoyed by the temperance movement. The Woman's Christian Temperance Union (WCTU), founded in 1873, drew widespread support from labor movements such as the Knights of Labor by linking the fight against liquor with the desire to protect home and family against the ravages of the new industrial order. Frances Willard was one of
"You Would Never Hear People Complain": Elfido Lpez Recalls Rural Mexican-American Life in the Late
The arrival of the railroad in the Southwest in the early 1870s transformed the area's economy and the lives of its residents. Long-time Mexican residents of the area were quickly drawn into the region's expanding wage economy. In this selection from his handwritten memoir from 1937 Elfido Lpez recalled his childhood on his family's modest homestead and his father's decision to move the family to a small railroad town, and a life of wages, in southern Colorado in 1876.
