River Against the Wall ebook

Rivers sustained fields, cities, and trade, yet their floods could erase a season of work in a single day. This history explores how early societies lived with that tension through irrigation, embankments, calendars, storage, and collective labor. From river valleys to growing urban centers, it shows how water shaped authority and cooperation without reducing civilization to a simple environmental story. The changing river remains a force that people studied, feared, and repeatedly tried to negotiate.
