The Christian-Democratic People's Party is a Christian-democratic political party in Moldova. The party was led by Iurie Roșca from 1994 until 2011. Until 2005, the PPCD and the (Moldovan) National Liberal Party were the main political organizations in the country supporting the unification of Moldova and Romania. After the PPCD began supporting the anti-unification Communist President Vladimir Voronin, the party has lost its unionist credentials while other parties such as the Liberal Party have taken over the pro-Romanian ideological space. The party has had very poor results in all subsequent elections. Since April 2005, the PPCD has lost several deputies, mayors, councillors and members to the liberal-democratic parties. The PPCD was an informal coalition partner of the Party of Communists of the Republic of Moldova from 2005–2009.

The unification of Moldova and Romania is a popular concept in the two countries that began during the Revolutions of 1989. The Romanian Revolution in 1989 and the independence of Moldova in 1991 further contributed to the development of a movement for the unification of the two Romanian-speaking countries. The question of reunification is recurrent in the public sphere of the two countries, often as a speculation, both as a goal and a danger. Though historically Romanian support for unification was high, a March 2022 survey following the Russian invasion of Ukraine indicated that only 11% of Romania's population supports an immediate union, while over 42% think it is not the right moment.
