A Year's Wage for Three Peaches: A Black Man Tells of Exploitation in the Late 19th century South
The harsh brutality of race relations in the late nineteenth-century South was sometimes best expressed through small incidents. For William Robinson, the story that best encapsulated his own experience growing up African-American in rural Georgia in the 1880s involved three peaches. He was interviewed by oral historian Charles Hardy in 1983 when Robinson was 103 years old. Apparently, some ninety-five years earlier when he was eight years old, three black boys sneaked into a peach orchard on th
"A Perfect Hailstorm of Bullets": A Black Sergeant Remembers the Battle of San Juan Hill in 1899
The best-known image of the Spanish-American War is that of Teddy Roosevelt on horseback charging with his Rough Riders up San Juan Hill in Cuba. But not only was the role of the Rough Riders exaggerated, it also displaced attention from the black soldiers who made up almost 25 percent of the U. S. force in Cuba. Indeed, the Spanish troops, who called the black soldiers "smoked Yankees," were often more respectful of the black troops than were the white officers who commanded them. Here Sergeant
A Georgia Sharecropper's Story of Forced Labor ca. 1900
At the turn of the century the group of black women most subject to sexual exploitation and abuse were those who lived under the system of quasi-slavery known as "peonage."Under contract labor laws, which existed in almost every southern state, a laborer who signed a contract and then quit his or her job could be arrested. The horrors of this system of forced labor (as well as the equally horrific system of convict labor) are detailed in this stark, turn-of-the-century personal account of life u

Insight into Practical Utilization of Knowledge Management Technologies
The focus of knowledge management (KM) has shifted in the last few years towards the ways in which knowledge is created and shared. Nevertheless, KM technologies continue to be an important issue in KM practices.

Utopian Hope and Apocalyptic Religion
Editor's note: The original event recording started slightly after the beginning of the introduction by Professor Lord Meghnad Desai. Where does the utopian impulse in politics originate, and does it have a future? John Gray argues that though they often claimed to be rooted in a scientific analysis of history and society the revolutionary political movements of the past were informed by a utopian vision which derives from religion. Is the age of secular utopianism over, and if so how will relig
Garibaldi: the patriot as global hero
The Italian revolutionary leader Giuseppe Garibaldi was not only worshipped as national hero in his country but he was also a hugely popular global figure in his lifetime - an estimated 500,000 people turned out to greet him on his arrival in London in 1864. The lecture, which marks the bicentenary of Garibaldi's birth, examines the charismatic leader's emergence as global symbol in the context of nineteenth-century globalization processes, developments in mass media, and political conflicts.
