In the United States, most folks have conceptions of the 1960s, 1970s, 1980s, etc. as different cultural eras, with distinct national moods and touchstones. I also know there's similar notions of "The Roaring Twenties" and "The Gay Nineties". But how far back does this cultural fascination with ten-year periods go? And how widely do other countries and communities subscribe to the same rubric?
