The Democratic Alliance (Italian: Alleanza Democratica, AD) was a social-liberal[4] political party in Italy.

AD was founded in 1993 with the intent of becoming the container of an alliance of centre-left forces;[5] however, the project did not succeed.

As such, AD acted as a minor social-liberal party, proposing economic liberalism, criticism of the Italian left's statism, and a shake-up of the political system.

[8] Most AD members continued to be part of the centre-left coalition, with the notable exceptions of Ferdinando Adornato and Giulio Tremonti, who would eventually join Forza Italia.

In the 1996 general election AD was a minor member of The Olive Tree,[9] and evolved into the Democratic Union (UD) with the entry of other Republicans such as Antonio Maccanico, and some Socialists including Giorgio Benvenuto.
