The notion that all people have certain rights, simply by virtue of being human, is a defining issue at the center of human history, and the struggle to define and achieve these rights remains an important issue today. This book traces the history of that struggle, from 3,000 B.C. (the first evidence of slavery in southern Mesopotamia) to 2002, when the U.S. Supreme Court affirmed the constitutionality of drug testing of student athletes.
