New from Harvard University Press: 
Justice Among Nations: A History of International Law (Feb. 2014), by 
Stephen C. Neff (University of Edinburgh). A description from the Press:
Justice among Nations tells 
the story of the rise of international law and how it has been 
formulated, debated, contested, and put into practice from ancient times
 to the present. 
Stephen Neff avoids technical jargon as he 
surveys doctrines from natural law to feminism, and practices from the 
Warring States of China to the international criminal courts of today. 
 
Ancient China produced the first rudimentary set of doctrines. But 
the cornerstone of later international law was laid by the Romans, in 
the form of natural law—a universal law that was superior to early laws 
and governments. As medieval European states came into contact with 
non-Christian peoples, from East Asia to the New World, practical 
solutions had to be devised to the many legal quandaries that arose. In 
the wake of these experiences, international legal doctrine began to 
assume its modern form in the seventeenth and eighteenth centuries. 
New challenges in the nineteenth century encompassed the advance of 
nationalism, the rise of free trade and European imperialism, the 
formation of international organizations, and the arbitration of 
disputes. Innovative doctrines included liberalism, the nationality 
school, and solidarism. The twentieth century witnessed the formation of
 the League of Nations and a World Court, but also the rise of socialist
 and fascist states and the advent of the Cold War. Yet the collapse of 
the Soviet Union brought little respite. As Neff makes clear, further 
threats to the rule of law today come from environmental pressures, 
genocide, and terrorism.
A few blurbs:
“Justice among Nations is by far the 
best general survey of the history of international law to date. It will
 be mandatory reading for both students and scholars in the field.”—Randall Lesaffer 
“Like Vattel’s 1758 Law of Nations, 
this sparkling and intelligent history is intended for a broad audience.
 Vattel reached his audience: George Washington and other Founding 
American Fathers are known to have possessed copies. Their vision for 
the new United States in the world was plainly influenced by it. Neff’s Justice among Nations
 refreshes Vattel for our time and our even more pressing need to 
understand what international law is and what it can accomplish for our 
common humanity.”—Mary Ellen O’Connell
