Transformation of NF to KÚ, elections to EP 2019 and NR SR 2020

On 8 February 2019, the party was renamed (registered on 27 August 1998), when on 7 January 2019, the statute and seat of this party changed and on February 8, 2019, it was renamed to the current name Christian Union. This transformation of this entity de facto created a new party, but de jure not^[5] This step, as the fragmentation of Christian forces and the promotion of Záborská's personal ambitions, was criticized by the chairman of KDH, Alojz Hlina.^[6] The founders did so so that they could avoid collecting 10,000 signatures to form a new political party.

In the 2019 European Parliament election, the party won 3.85% of the vote and did not win any seats.

After the elections, the need to unite Christian political forces with KDH or KDŽP was discussed. In the end, the merger did not take place in the autumn of 2019, as President Alojz Hlina offered the Christian Union only 2 seats as a KDH candidate.^[7] On the contrary, the KU came closer to the OĽANO movement, on whose candidate list OĽaNO in the parliamentary elections 19 candidates for the KÚ ran, while its chairwoman Anna Záborská ran from 4th place.^[8] NOVA and Zmena Zdola did the same with OĽaNO in order to avoid an increased clause for electoral coalitions.^[9]

OĽaNO, together with the KÚ, also offered the pre-election procedure to the KDH, to which it offered half the seats on the candidate and, after the elections, its own parliamentary club. KDH rejected this offer.^[10]
