How has equality change over time through social movements and policies (economics, laws, philosophies...)?

The phrase social movements refers to collective activities designed to bring about or resist primary changes in an existing society or group. Wherever they occur, social movements can dramatically shape the direction of society. ... Even when they prove initially unsuccessful, social movements do affect public opinion.

Explanation:

Social movements are purposeful, organized groups striving to work toward a common goal. These groups might be attempting to create change (Occupy Wall Street, Arab Spring), to resist change (anti-globalization movement), or to provide a political voice to those otherwise disenfranchised (civil rights movements).
