A monumental undertaking. A stunning academic achievement. ABC-CLIO's World History Encyclopedia is the first comprehensive work to take a large-scale thematic look at the human species worldwide. Comprised of 21 volumes covering 9 eras, an introductory volume, and an index, it charts the extraordinary journey of humankind, revealing crucial connections among civilizations in different regions through the ages. Within each era, the encyclopedia highlights pivotal interactions and exchanges among cultures within eight broad thematic categories: population and environment, society and culture, migration and travel, politics and statecraft, economics and trade, conflict and cooperation, thought and religion, science and technology. Aligned to national history standards and packed with images, primary resources, current citations, and extensive teaching and learning support, the World History Encyclopedia gives students, educators, researchers, and interested general readers a means of navigating the broad sweep of history unlike any ever published.
