According to Sand, the description of the Jews as a wandering and self-isolating nation of exiles, "who wandered across seas and continents, reached the ends of the earth and finally, with the advent of Zionism, made a U-turn and returned en masse to their orphaned homeland," is nothing but "national mythology." Like other national movements in Europe, which sought out a splendid Golden Age, through which they invented a heroic past - for example, classical Greece or the Teutonic tribes - to prove they have existed since the beginnings of history, "so, too, the first buds of Jewish nationalism blossomed in the direction of the strong light that has its source in the mythical Kingdom of David." So when, in fact, was the Jewish people invented, in Sand's view? At a certain stage in the 19th century, intellectuals of Jewish origin in Germany, influenced by the folk character of German nationalism, took upon themselves the task of inventing a people "retrospectively," out of a thirst to create a modern Jewish people. From historian Heinrich Graetz on, Jewish historians began to draw the history of Judaism as the history of a nation that had been a kingdom, became a wandering people and ultimately turned around and went back to its birthplace.
