The creation of the team was a requirement of the body which brought together the European Christian Democratic parties, which only contemplated a member per country.

Shortly after the Social Christian Democracy joined, led by José María Gil-Robles, without the reticence of the Basque and Catalan nationalists.

Only in March 1973 they took place the First Conference of the Christian Democratic Team of the Spanish State (EDCEE) at the Abbey of Montserrat, where a federalist program was defined.

In any case, the team doesn't developed a unified political action, with each of the parties, especially the Basque and Catalan nationalists, acting for free.

The results were very bad (215,841 votes, 1.18%) without getting the team any seats in Congress, and it was dissolved and its members defected to the Union of the Democratic Centre or People's Alliance.
