The Quiet Revolution began in earnest during the 1960s. The expression of Quebecois identity, or even nationalist sentiment, shaped much of Quebecois literature in the period 1960 to 1970. The Cold War, the feminist movement, the influence of the United States' "counterculture", the concerns of the baby boom generation, and other cultural developments sweeping the Western world during the era also permeated the works of Quebec writers.
