Book excerpt: Barack Obama, the first African-American president of the United States. In a country with a rich history of racial animosities, Obama represents a notable deviation in the trajectory of America’s presidential history. At the close of his second term in office, a survey of the personalities and events associated with his presidency is fitting. In this walk through recent history we will be keen to point out the president’s successes, failures, and challenges. Governing in a society ripe with ideological and partisan polarization, the Obama Administration was surrounded by controversy, much of it manufactured by his opponents but salient nonetheless. This volume will attempt to provide perspective and clarity on the most important individuals and experiences connected to Obama during his eight years in office, but also his early life. Information included in this volume also includes discussion of his transition out of office and events taking place at the beginning of the Donald Trump Administration. This second edition of Historical Dictionary of the Barack Obama Administration contains a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 300 cross-referenced entries on important personalities, including the president, his advisors, his family, his opponents, and his critics, as well as members of Congress, military leaders, and international leaders. This book is an excellent resource for students, researchers, and anyone wanting to know more about Barack Obama.
