Offering exhaustive coverage, detailed analyses, and the latest historical interpretations of events, this expansive, five-volume encyclopedia is the most comprehensive and detailed reference source on the First World War available today.

One hundred years after the beginning of World War I in 1914, this conflict still stands as perhaps the most important event of the 20th century. World War I toppled all of the existing empires at the time, transformed the Middle East, and vaulted the United States to becoming the world’s leading economic power. Its effects were profound and lasting-and included outcomes that led to World War II. This multivolume encyclopedia provides a wide-ranging examination of World War I that covers all of the important battles; key individuals, both civilian and military; weapons and technologies; and diplomatic, social, political, cultural, military, and economic developments.

Suitable as a reference tool for high school and undergraduate students as well as faculty members and graduate-level researchers, World War I: The Definitive Encyclopedia and Document Collection offers accessible, in-depth information and up-to-date analyses in a format that lends itself to quick and easy use.
