Christian Democracy (Italian: Democrazia Cristiana, DC) was a Christian democratic political party in Italy. The DC was founded on 15 December 1943 in the Italian Social Republic (Nazi-occupied Italy) as the ideal successor of the Italian People's Party, which had the same symbol, a crusader shield (scudo crociato). As a Catholic-inspired, centrist, catch-all party comprising both centre-right and centre-left political factions, the DC played a dominant role in the politics of Italy for fifty years, and had been part of the government from soon after its inception until its final demise on 16 January 1994 amid the Tangentopoli scandals. Christian Democrats led the Italian government continuously from 1946 until 1981. The party was nicknamed the "White Whale" (Italian: Balena bianca) due to its huge organisation and official colour. During its time in government, the Italian Communist Party was the largest opposition party.

From 1946 until 1994, the DC was the largest party in the Italian Parliament, governing in successive coalitions, including the Pentapartito system. It originally supported liberal-conservative governments, along with the moderate Italian Democratic Socialist Party, the Italian Liberal Party, and the Italian Republican Party, before moving towards the Organic Centre-left involving the Italian Socialist Party. The party was succeeded by a string of smaller parties, including the Italian People's Party, the Christian Democratic Centre, the United Christian Democrats, and the still active Union of the Centre. Former DC members are also spread among other parties, including the centre-right Forza Italia and the centre-left Democratic Party. It was a founding member of the European People's Party in 1976.
