After the disappointing results of the Union of the Centre in the 2013 Italian general election, Mario Tassone, in disagreement with the party strategies and on the alliance with Civic Choice, called the national council of the United Christian Democrats on 11 May 2013, although he declared that he had no intention of founding a new party.

[1][2] On 6 July 2013 Tassone was so referred to the arbitrators by the UDC's Calabrian regional committee for his expulsion.

[3][4] On 16 March 2014, in the fourth CDU congress, Tassone was appointed secretary of the reborn party,[5] while up to that moment he had been president of the United Christian Democrats' association which had never been definitively dissolved.

[6] The New CDU ran in the 2014 Calabrian regional election within the centre-left coalition, but with 1.5% of the vote it gained no seat.

[8][9] On 19 December 2018 Gianfranco Rotondi, president of the Federation of Christian Democracy, Mario Tassone, secretary of the New CDU, Giorgio Merlo, leader of "White Network" and Renato Grassi, secretary of the historical Christian Democracy, signed a federative pact for the reconstitution of the Christian Democracy,[10] that, on 8 June 2019, became a foundation.
