Set in a large townhouse in Belgravia in central London, the series depicts the servants—"downstairs"—and their masters, the family—"upstairs"—between the years 1903 and 1930, and shows the slow decline of the British aristocracy. Great events feature prominently in each episode but minor or gradual changes are also noted. The show stands as a document of the social and technological changes that occurred between those 27 years, including the Edwardian period, women's suffrage, the First World War, the Roaring Twenties, and the Wall Street Crash. It was a ratings success for ITV and received outstanding acclaim worldwide, winning multiple awards.
