The Rhine River is Europe?s most important commercial waterway, channeling the flow of trade among Switzerland, France, Germany, and the Netherlands. In this innovative study, Mark Cioc focuses on the river from the moment when the Congress of Vienna established a multinational commission charged with making the river more efficient for purposes of trade and commerce in 1815. He examines the engineering and administrative decisions of the next century and a half that resulted in rapid industrial growth as well as profound environmental degradation, and highlights the partially successful restoration efforts undertaken from the 1970s to the present.
