When on Earth?

Incredible maps show where history was made. Much more than an atlas or a history book, When on Earth? charts global historical events through stunning world maps. A truly visual guide to discovering when, where, and why things happened, When on Earth? presents history as a series of stunning, specially commissioned historical maps of the world. Each of these maps charts a key global event, such as the migration of the earliest humans, the spread of the Black Death, or the European, African, and Pacific theaters of World War II.
