Conservatism is a political and social philosophy promoting traditional social institutions in the context of culture and civilization. The central tenets of conservatism include tradition, human imperfection, organic society, hierarchy, authority, and property rights. Conservatives seek to preserve a range of institutions such as religion, parliamentary government, and property rights, with the aim of emphasizing social stability and continuity. The more traditional elements—reactionaries—oppose modernism and seek a return to "the way things were".
The first established use of the term in a political context originated in 1818 with François-René de Chateaubriand during the period of Bourbon Restoration that sought to roll back the policies of the French Revolution. Historically associated with right-wing politics, the term has since been used to describe a wide range of views. There is no single set of policies regarded as conservative because the meaning of conservatism depends on what is considered traditional in a given place and time. Thus conservatives from different parts of the world—each upholding their respective traditions—may disagree on a wide range of issues. Edmund Burke, an 18th-century politician who opposed the French Revolution but supported the American Revolution, is credited as one of the main theorists of conservatism in Great Britain in the 1790s.
According to Quintin Hogg, the chairman of the British Conservative Party in 1959: "Conservatism is not so much a philosophy as an attitude, a constant force, performing a timeless function in the development of a free society, and corresponding to a deep and permanent requirement of human nature itself". In contrast to the tradition-based definition of conservatism, some political theorists such as Corey Robin define conservatism primarily in terms of a general defense of social and economic inequality. From this perspective, conservatism is less an attempt to uphold traditional institutions and more, "a meditation on—and theoretical rendition of—the felt experience of having power, seeing it threatened, and trying to win it back".
