Christian democracy is a political ideology which emerged in nineteenth-century Europe under the influence of conservatism and Catholic social teaching, as well as Neo-Calvinism. It was originally conceived as a combination of traditional Catholic beliefs and modern democratic ideas, and it grew to incorporate the social teaching of other Christian denominations, such as the Lutheran Church and the Reformed Church. After World War II, the Protestant and Catholic movements of the Social Gospel and Neo-Thomism, respectively, played a role in shaping Christian democracy. Christian democracy continues to be influential in Europe and Latin America, although it is present in other parts of the world too.
In practice, Christian democracy is often considered centre-right on cultural, social, and moral issues (and is thus a supporter of social conservatism), and it is considered centre-left "with respect to economic and labor issues, civil rights, and foreign policy." Specifically, with regard to its fiscal stance, Christian democracy advocates a social market economy. In Europe, where Christian democrats defined their views as an alternative to the more leftist ideology of social democracy, Christian democratic parties are moderately conservative and centre-right overall, whereas in the very different cultural and political environment of North and South America they tend to lean to the left in economical issues, and to the right in social issues.
