Book excerpt: How do civilizations rise and, ultimately, fall? U.S. students can have a difficult time understanding that empires come and go throughout the course of history. This volume explains how a once-flourishing civilization ran into decline, once foreign invaders took over the weakened government and spread their influence. Students will learn how India evolved into the country it is today. With engaging text, rich and colorful illustrations, and an enhanced e-book option, this title is a valuable resource for students researching reports.
