The Progressive Era, the period in the United States between 1898 and 1917, was a time of great social, political, and industrial change. Following the Spanish-American War of 1898, an event that signaled the emergence of the United States as a great power, the country soon was involved in its first overseas guerrilla war, in the Philippines. Vast changes in communications and transportation, immigration and migration patterns, social mores, gender roles, family structure, class structure, work patterns, business methods, education, intellectual life, religion, the professions, technology, science, medicine, and much else were transforming the scope and feel of people's lives and relationships. In many ways what happened in this era set the agenda for the rest of the 20th century.The A to Z of the Progressive Era is the most comprehensive and coherent reference work on the Progressive Era.
