The idea that the histories of different regions in the world are interconnected is not particularly novel; it already existed several centuries ago. Thus, for example, when the German historian and playwright Friedrich Schiller was granted a chair at the University of Jena in 1789, he declared in his inaugural address that “the most remote regions of the world contribute to our luxury.” After all, he continued, “The clothes we wear, the spices in our food, and the price for which we buy them, many of our strongest medicines, and also many new tools of our destruction—do they not presuppose a Columbus who discovered America, a Vasco da Gama who circumnavigated the tip of Africa”?2 Nevertheless it took quite some time before professional historians began to consider these global connections seriously in their research. Colonial and “imperial” historians led the way. They were joined by economic historians. Labor historians became interested in intercontinental perspectives only more recently; until the 1970s, they typically locked themselves into the framework of individual nation-states. Even great innovators in the discipline, such as E. P. Thompson, thought mostly in terms of “national” working classes.
