Liberalism is a political and moral philosophy that prioritizes the protection and promotion of individual freedom and rights. It is based on the beliefs in individual rights, consent of the governed, political equality, and the right to private property. Liberalism advocates for a justified exercise of political authority and law, and challenges unchecked power in political systems. It has been the dominant political ideology and is centered around the individual's ability to pursue and realize their own interests. Originating from philosophers such as John Locke, liberalism has inspired political systems, such as democracy, that protect the liberty and life of citizens. However, the interpretation of liberalism is subject to variation and can include different beliefs and applications. Ultimately, liberalism is a collection of theories that prioritize individual rights, liberty, and consent of the governed.
