The history and theory of international law have been transformed in recent years by post-colonial and post-imperial critiques of the universalistic claims of Western international law. The origins of those critiques lie in the often overlooked work of the remarkable Polish-British lawyer-historian C. H. Alexandrowicz (1902-75). This volume collects Alexandrowicz's shorter historical writings, on subjects from the law of nations in pre-colonial India to the New International Economic Order of the 1970s, and presents them as a challenging portrait of early modern and modern world history seen through the lens of the law of nations. The book includes the first complete bibliography of Alexandrowicz's writings and the first biographical and critical introduction to his life and works. It reveals the formative influence of his Polish roots and early work on canon law for his later scholarship undertaken in Madras (1951-61) and Sydney (1961-67) and the development of his thought regarding sovereignty, statehood, self-determination, and legal personality, among many other topics still of urgent interest to international lawyers, political theorists, and global historians.
