“Sovereignty” was not always there. What is called “sovereignty” today emerged under certain historical conditions at a certain time and in a certain place, and it can disappear or lose its meaning if the conditions change. Some authors assume that this has already happened so that we find ourselves in a post-sovereign era. The best way to ascertain whether they are right seems to be a reconstruction of the conditions under which sovereignty originally emerged, followed by an analysis as to whether the conditions have changed in the meantime, and, if so, how the changes affect sovereignty. Without such a historical assessment it is difficult to understand the present situation.
