Cowboy Presidents
Author: David A. Smith
Publisher: University of Oklahoma Press
ISBN: 0806169699
Category : Political Science
Languages : en
Pages : 405
Book Description
For an element so firmly fixed in American culture, the frontier myth is surprisingly flexible. How else to explain its having taken two such different guises in the twentieth century—the progressive, forward-looking politics of Rough Rider president Teddy Roosevelt and the conservative, old-fashioned character and Cold War politics of Ronald Reagan? This is the conundrum at the heart of Cowboy Presidents, which explores the deployment and consequent transformation of the frontier myth by four U.S. presidents: Theodore Roosevelt, Lyndon B. Johnson, Ronald Reagan, and George W. Bush. Behind the shape-shifting of this myth, historian David A. Smith finds major events in American and world history that have made various aspects of the “Old West” frontier more relevant, and more useful, for promoting radically different political ideologies and agendas. And these divergent adaptations of frontier symbolism have altered the frontier myth. Theodore Roosevelt, with his vigorous pursuit of an activist federal government, helped establish a version of the frontier myth that today would be considered liberal. But then, Smith shows, a series of events from the Lyndon Johnson through Jimmy Carter presidencies—including Vietnam, race riots, and stagflation—seemed to give the lie to the progressive frontier myth. In the wake of these crises, Smith’s analysis reveals, the entire structure and popular representation of frontier symbols and images in American politics shifted dramatically from left to right, and from liberal to conservative, with profound implications for the history of American thought and presidential politics. The now popular idea that “frontier American” leaders and politicians are naturally Republicans with conservative ideals flows directly from the Reagan era. Cowboy Presidents gives us a new, clarifying perspective on how Americans shape and understand their national identity and sense of purpose; at the same time, reflecting on the essential mutability of a quintessentially national myth, the book suggests that the next iteration of the frontier myth may well be on the horizon.

Why I Hate Green Beans
Author: Lincee Ray
Publisher: Baker Books
ISBN: 1493412590
Category : Religion
Languages : en
Pages : 201
Book Description
If there is one thing Lincee Ray has learned over the years, it's that the majority of women on the planet struggle with insecurities. Our skinny jeans mock us. Our just-trying-to-help mothers are just driving us crazy. Our social media feeds taunt us with everyone else's picture-perfect lives. It's enough to send you on a gummy-bear bender while binge-watching Friends reruns and not showering for a week. Lincee knows. She's been there. Right there, in fact. Gummy bears and all. For every woman who's ever wondered if she's unlovable, uninteresting, or unattractive, Lincee offers her particular brand of hilarious (and hard-hitting) self-reflection. Like a true friend, she shows us that the fastest way to happiness is to embrace ourselves in all our imperfection, trust that God knew what he was doing when he made us, and maybe go buy a new tube of mascara. Walk alongside Lincee as she discovers that her identity is not found in her job, her relationship status, her bank account, or her social circle. It's found in Christ.

Black Cowboys in the American West
Author: Bruce A. Glasrud
Publisher: University of Oklahoma Press
ISBN: 0806156503
Category : History
Languages : en
Pages : 263
Book Description
Who were the black cowboys? They were drovers, foremen, fiddlers, cowpunchers, cattle rustlers, cooks, and singers. They worked as wranglers, riders, ropers, bulldoggers, and bronc busters. They came from varied backgrounds—some grew up in slavery, while free blacks often got their start in Texas and Mexico. Most who joined the long trail drives were men, but black women also rode and worked on western ranches and farms. The first overview of the subject in more than fifty years, Black Cowboys in the American West surveys the life and work of these cattle drivers from the years before the Civil War through the turn of the twentieth century. Including both classic, previously published articles and exciting new research, this collection also features select accounts of twentieth-century rodeos, music, people, and films. Arranged in three sections—“Cowboys on the Range,” “Performing Cowboys,” and “Outriders of the Black Cowboys”—the thirteen chapters illuminate the great diversity of the black cowboy experience. Like all ranch hands and riders, African American cowboys lived hard, dangerous lives. But black drovers were expected to do the roughest, most dangerous work—and to do it without complaint. They faced discrimination out west, albeit less than in the South, which many had left in search of autonomy and freedom. As cowboys, they could escape the brutal violence visited on African Americans in many southern communities and northern cities. Black cowhands remain an integral part of life in the West, the descendants of African Americans who ventured west and helped settle and establish black communities. This long-overdue examination of nineteenth- and twentieth-century black cowboys ensures that they, and their many stories and experiences, will continue to be known and told.
