With optional Hebrew subtitles. Simon Schama's history of the Jewish experience plunges into the lost world of the shtetl, the Jewish towns and villages sewn across the hinterlands of Eastern Europe which became the seedbed of a uniquely Jewish culture. Shtetl culture would make its mark on the modern world, from the revolutionary politics of the Soviet Union to the mass culture of Tin Pan Alley and Hollywood. It was also the birthplaces of Hasidism, the most visible, iconic and, arguably, most misunderstood expression of Jewish faith and fervour. This chapter of the story travels from the forests of Lithuania, where Simon's own family logged wood and fought wolves, to the streets of the Lower East Side where the sons of shtetl immigrants wrote the American songbook. With grim inevitability, the story returns to Eastern Europe in 1940 - where the genocidal mechanisms of the 'final solution' were beginning to grind the shtetl world into dust and ash.
