Please answer the following question: Information:  - 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.  - The Centrist Democrat International is Christian Democrat political international. Until 2001 it was known as the Christian Democrat International (CDI) and before that the "Christian Democrat and People's Parties International" (until 1999) (this earlier name is, since October 2000, still sometimes used colloquially). It was formed in 1961 in Santiago, Chile as the "Christian Democrat World Union", building on the legacy of other Christian Democrat internationals who tried to create a Christian-inspired third way alternative to the socialist internationals; in 1982 it was renamed for the first time Christian Democrat International. The name officially changed due to the participation of groups of various faiths. It is the global international political group dedicated to the promotion of Christian democracy. Although it gathers parties from around the globe, its members are drawn principally from Europe and Latin America. Some of them are also members of the International Democrat Union (IDU), although the CDI is closer to the political centre and more communitarian than the IDU.  - A European political party (formally, a political party at European level; informally a Europarty) is a type of political party organisation operating transnationally in Europe and in the institutions of the European Union. They are regulated and funded by the European Union and are usually made up of national parties, not individuals. Europarties have the exclusive right to campaign during the European elections and express themselves within the European Parliament by their affiliated political groups and their MEPs. Europarties, through coordination meetings with their affiliated heads of state and government, influence the decision-making process of the European Council. Europarties also work closely and co-ordinate with their affiliated members of the European Commission and, according to the Lisbon Treaty the Europarty that wins the European elections has the right to nominate to the European Council its candidate for President of the European Commission.  - The Inter-Parliamentary Union (IPU) is a global inter-parliamentary institution established in 1889 by Frédéric Passy (France) and William Randal Cremer (United Kingdom). It was the first permanent forum for political multilateral negotiations. Initially, the organization was for individual parliamentarians, but has since transformed into an international organization of the parliaments of sovereign states. The national parliaments of 170 countries are members of the IPU, and 11 regional parliamentary assemblies are associate members. The IPU has permanent observer status at the United Nations General Assembly and general consultative status with the Economic and Social Council.  - Santiago de Chile is the capital and largest city of Chile. It is also the center of its largest conurbation. Santiago is located in the country's central valley, at an elevation of above mean sea level.  - The European People's Party (EPP) is a European political party. A transnational organisation, it is composed of other political parties, not individuals.

Its secretary is Lorenzo Cesa , but its most popular figure and actual leader is Pier Ferdinando Casini . The party is a member of the European People 's Party and the Centrist Democrat International , of which Casini is president . The party was formed in December 2002 as the Union of Christian and Centre Democrats ( Unione dei Democratici Cristiani e di Centro , UDC ) as the merger of the Christian Democratic Centre , the United Christian Democrats and European Democracy .

Since then , the party 's official name was neglected in favour of `` Union of the Centre '' and , since most of the UdC member parties have joined the UDC too , the UDC and the UdC started to overlap almost completely to the point that they are now undistinguishable . The UDC was part of the Pole / House of Freedoms from its establishment through 2008 . Later it has been affiliated neither to the centre - right nor the centre - left at the national level . Despite this , the party takes part in several regional , provincial and municipal governments with Forza Italia , the largest force of the Italian centre - right ( notably in Campania and Calabria ) , but recently formed alliances also with the centre - left Democratic Party in other regions ( notably in Marche ) and at the very local level .
