Download or read book The Long Lingering Shadow written by Robert J. Cottrol and published by University of Georgia Press. This book was released on 2013-02-01 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Students of American history know of the law’s critical role in systematizing a racial hierarchy in the United States. Showing that this history is best appreciated in a comparative perspective, The Long, Lingering Shadow looks at the parallel legal histories of race relations in the United States, Brazil, and Spanish America. Robert J. Cottrol takes the reader on a journey from the origins of New World slavery in colonial Latin America to current debates and litigation over affirmative action in Brazil and the United States, as well as contemporary struggles against racial discrimination and Afro-Latin invisibility in the Spanish-speaking nations of the hemisphere. Ranging across such topics as slavery, emancipation, scientific racism, immigration policies, racial classifications, and legal processes, Cottrol unravels a complex odyssey. By the eve of the Civil War, the U.S. slave system was rooted in a legal and cultural foundation of racial exclusion unmatched in the Western Hemisphere. That system’s legacy was later echoed in Jim Crow, the practice of legally mandated segregation. Jim Crow in turn caused leading Latin Americans to regard their nations as models of racial equality because their laws did not mandate racial discrimination— a belief that masked very real patterns of racism throughout the Americas. And yet, Cottrol says, if the United States has had a history of more-rigid racial exclusion, since the Second World War it has also had a more thorough civil rights revolution, with significant legal victories over racial discrimination. Cottrol explores this remarkable transformation and shows how it is now inspiring civil rights activists throughout the Americas.

Download or read book Saracen Tales written by Giuseppe Bonaviri and published by Crossings. This book was released on 2007 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiction. Short Stories. Translated from the Italian by Barbara De Marco. In SARACEN TALES, Italian-born Giuseppe Bonaviri brings a wild newness to the tale of the life of Jesus. In this succession of stories, Bonaviri explores all manners of the known and unknown, the archetypal, the mythological, the symbolic--the life of Jesus is both his material and his point of departure. Part surrealism, part folklore, readers will be amazed at the originality and creativity with which a long-familiar tale is presented. "Bonaviri is a myth-maker, looking simultaneously to the historical past and to the future, to arrive at the a-historical, at cosmic universality"--Franco Zangrilli. Giuseppe Bonaviri was born in 1924 in Sicily. He began writing when he was ten and continued through high school, college, and in his professional life as a doctor, health official, and cardiologist. His work has been widely translated.

Download or read book Afro Argentine Discourse written by Marvin A. Lewis and published by . This book was released on 1996 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Afro-Argentine Discourse, Marvin A. Lewis attempts to write blacks back into the literary history of Argentina by treating in depth, for the first time, the written expression of Argentines of African descent during the late nineteenth and early twentieth centuries. Because their contributions are overlooked or minimized in most literary histories, it is often assumed that blacks had little or no part in the development of Argentine literature. Through original archival research, Lewis corrects this erroneous assumption by examining texts never before made available to the academic community. Afro-Argentine Discourse investigates a new dimension of the black experience in the Americas and will stir much interest and debate regarding the black presence in Argentina.
