The roots of liberal thought can be traced back to the works of early modern philosophers such as John Locke, whose ideas on natural rights and government by consent laid the foundation for liberal political theory. Locke’s assertion that individuals possess inherent rights to life, liberty, and property formed the basis for much of liberal thought, influencing the development of constitutionalism and democratic governance. Over time, thinkers like Montesquieu, Rousseau, and later John Stuart Mill contributed to the evolution of liberalism, expanding its focus to issues of civil liberties, political freedoms, and social equality.
A defining characteristic of liberalism is its emphasis on individual freedom. This includes both personal liberty—the freedom to make choices about one’s own life—and political liberty—the right to participate in the democratic process and have a say in the laws and policies that govern society. Classical liberals advocated for minimal government interference in the economy and individual affairs, emphasizing free markets, private property, and limited state power. The role of the state, in this view, is to protect the rights of individuals and maintain social order, but not to intervene in the private lives or economic transactions of citizens.
