Liberalism focuses on freedom, liberty, individualism, limited government, tolerance, justice, and equal rights. It originated during the Enlightenment period from 1699-1800, where thinkers like John Locke and Thomas Jefferson emphasized concepts like individual consent to government and the pursuit of happiness. Jean-Jacques Rousseau also influenced liberalism with his view that people are born free but placed in chains by societies and governments that deny human rights and basic freedoms. Liberalism supports constitutional, limited government that does not interfere with individual interests, as well as pluralism, tolerance of different lifestyles, and equality of opportunity.
