The Quiet Revolution was a period of unbridled economic and social development in Quebec and Canada and paralleled similar developments in the West in general. It was a byproduct of Canada's 20-year post-war expansion and Quebec's position as the leading province for more than a century before and after Confederation.
The Liberals promised to do two things during the Quiet Revolution; one was to improve economic and social standards for the people of Quebec, and the other was to win greater respect and recognition for all the French people of Canada. The Liberals started a program to take control of hydro-electric power companies.
