Explanation:

Liberalism refers to a political idea and a moral philosophy which primarily deals with the concept of liberty. The foundation of this idea is dependent on three concepts: liberty, consent of the people being governed, and equality before law. The practitioners of this political idea, the liberals, are staunch believers of individual rights and limited government. They also propagate free markets, democracy, secularism, gender equality, freedom of speech, press and religion.
