The party was found by Monteiro in protests of the policies of the Democratic and Social Centre – People's Party, which became supportive of the European Union and the European integration. The party campaigned on growing disappointment of the CDS-PP.[1]
The presence of the New Democracy Party caused the CDS-PP to face tensions with its coalition partner, the moderate Força Portugal. The CDS-PP also continously pressured João de Deus Pinheiro to not debate Manuel Monteiro, which led Monteiro to accuse main Portuguese parties of discriminating him.[1]
The party's registration was cancelled by the Constitutional Court on 23 September 2015, after the party failed to submit its required annual report in 2011, 2012, and 2013.
