"This unique book examines the history, culture, and inner workings of the seven smallest independent countries in Europe. These are among the oldest states on the continent and, despite their diversity, they have much in common. Most have relatively high per capita incomes and life expectancies, and relatively low unemployment. This narrative presents the unique issues that confront small countries, including maintaining their independence, economic viability, preserving their native languages, and sustaining their governments. The second part of the book describes each microstate in turn, showing how each one has met these challenges and adapted over time. These concise and engaging chapters contain cultural information on subjects including the arts, gastronomy, and popular tourist sites."--Provided by publisher.

In substantial selections from his earliest writings, the Notes on Virginia, his public papers, and his personal correspondence, this volume traces the development of Jefferson's thinking on such fundamental issues as republicanism, constitutionalism, political parties, and the separation of religion from politics. His proposals for the education of women, the emancipation of slaves, and the expatriation of Native Americans are included, along with a number of intimate letters illustrating the range of Jefferson's interests and offering a peek into his private life. Drawing on the best Jeffersonian scholarship of the last thirty years, Yarbrough's Introduction sets Jefferson's life and writing in context and illuminates the ways in which his understanding of human nature influenced his political views. A brief headnote introduces each selection and provides crucial background information; footnotes offer concise biographies of Jefferson's correspondents and identify other important figures and events. An index and select bibliography are also included.
Thomas Jefferson (1743-1826) was the third United States President (1801-9) and the principal author of the Declaration of Independence. An advocate of republicanism, he envisioned America as an 'Empire of Liberty' that would strive to promote freedom around the world. First published in 1853-4, this nine-volume edition of Jefferson's writings shows the breadth of his intellectual and political interests. His autobiography, letters, diaries and political memoranda reflect a life lived at the centre of pivotal events, including the French and American Revolutions, and the founding of a new nation. Through them we discover the evolving relationships between the United States and the European powers, and the development of the American constitution and judicial system. Volume 9 contains a selection of documents showing the depth and range of Jefferson's diplomatic, political and scientific activities throughout his career, and an index to all the volumes.
