However, the charter and other resolutions did not insist on full independence as the best way of obtaining self-government, nor did they include an enforcement mechanism. Moreover, new states were recognized by the legal doctrine of uti possidetis juris, meaning that old administrative boundaries would become international boundaries upon independence if they had little relevance to linguistic, ethnic, and cultural boundaries. Nevertheless, justified by the language of self-determination, between 1946 and 1960, thirty-seven new nations in Asia, Africa, and the Middle East gained independence from colonial powers. The territoriality issue inevitably would lead to more conflicts and independence movements within many states and challenges to the assumption that territorial integrity is as important as self-determination.
