Women's liberation movement
The women's liberation movement (WLM), or women's lib for short, was a diverse sub-movement within second-wave feminism, broadly falling under radical and sometimes liberal feminism, which proposed that the furthering of economic, psychological, and social freedoms was necessary for women to progress from being second-class citizens in their societies. It emerged in the late 1960s and continued till the 1980s, primarily in the industrialized nations of the Western world, which resulted in great change (political, intellectual, and cultural) throughout the world.
