That’s the topic of my latest column at RealClearHistory. An excerpt:
2. Sovereignty and suzerainty are concepts that have little to no bearing on today’s world, but perhaps they should. Prior to the end of World War II, when the U.S. and U.S.S.R. became the globe’s alpha powers, suzerainty was often used by imperial powers to manage their colonies. Suzerainty is a formal recognition, by a power, of a minor polity’s independence and autonomy, and a formal recognition by the minor polity of the power’s control over its diplomatic and economic affairs. Suzerainty was used especially often by the British and Dutch (and less so by France and other Latin states, which preferred more direct control over their territorial claims), as well as the Ottoman Empire. The U.S.-led order has focused on sovereign states rather than unofficial spaces, and this has led to many misunderstandings. Somalia, which has long been a region of suzerains, is a basketcase today largely because it is approached by powers as a sovereign state.
Please, read the rest. The Dervish state was an ally of the Ottoman and German empires during World War I.
