The party took part in the
2006 Polish local elections, putting up a list for the municipal council of
Olszewo-Borki - 9.13% (68) of the vote - and to the municipal council of
Wrocław - 0.08% (21) of the vote. The party then participated in the early elections to the
Podlaskie Voivodeship Sejmik on 20 May 2007, and did not win any seats. The party intended to run in the
2007 Polish parliamentary election, but did not register any candidate. It was also the case for the
2009 European Parliament election in Poland, where despite the registration of the committee, it failed to put forward any electoral list (
Krzysztof Kononowicz). In the
2010 Polish presidential election, Slavic Union fielded the candidacy of Krzysztof Mazurski, who failed to collect 100.000 signatures and was not registered. In the
2010 Polish local elections, Slavic Union fielded candidates in all districts for the
Masovian Voivodeship Sejmik. Its list received 0.31% (5707) of the votes. In addition, Slavic Union won two seats in municipal councils. In the
2011 Polish parliamentary election, the party registered its candidate Anita Walotek in the Sosnowiec-Jaworzno district, who received 2.35% (2,977) of the vote, coming in last, 6th place. In the
2014 European Parliament election in Poland, Slavic Union again failed to field any electoral list, despite registering a committee. In the
local elections in the same year, ZS fielded lists in all districts for the Mazovian Voivodeship assembly, receiving 0.37% (6621) of the vote. In addition, the party won eight seats in municipal councils. In the
2015 Polish parliamentary election, Slavic Union fielded a candidate for the
Senate, Zbigniew Adamczyk, in the Grudziądz district. He received 8.96% (9562) of the vote, coming in last, 4th place. In the
2018 Polish local elections, the party registered its own committee, fielding lists in half of the districts for the
Kuyavian-Pomeranian Voivodeship Sejmik. It received 0.42% of the vote (3286) on a provincial scale. In the
2019 Polish parliamentary election in
district no. 12, the party again fielded Zbigniew Adamczyk for the Senate. Vice-chairman of the ZS
Zdzisław Jankowski, meanwhile, opened the Konin list of
Zjednoczeni Ponad Podziałami to the
Sejm (received 679 votes). Zbigniew Adamczyk in the Senate district received 6.32% (8469) of the votes, coming in penultimate, 4th place. Also, Zbigniew Adamczyk entered as a candidate in the
2020 Polish presidential election, however, he did not collect the required number of signatures, and after the vote did not take place, he did not register the committee in the second round. On 11 August 2023, the party registered an electoral committee for the
2023 Polish parliamentary election. The party shocked the pundits by fielding controversial businessman
Stanisław Tymiński as one of its two candidates for the Senate. Tymiński is a populist businessman who lived in Canada before returning to Poland and partaking in the
1990 Polish presidential election, where he shocked the media by taking second place in the first round as an "out of nowhere" dark horse candidate. Tymiński had many political labels attached to him during the election, being described as, among others, a "progressive libertarian, civilised capitalist, and ended up as a reactionary
endek, Darwinist, almost (or even) fascist". Amongst media-sparked controversies such as Tymiński allegedly abusing his wife and having links to Colombian drug mafia, Tymiński lost in a landslide to
Lech Wałęsa. Explaining his decision to run again after 30 years, Tymiński wrote: "For many years I have been observing how much our country has changed, which is completely dependent on foreign capital. As long as Poland's budget is kept on a drip of loans, foreign capitalists have profit. In such a situation, the only thing left is the possibility of diplomatic negotiations, because we cannot afford to fight with an open visor. And to negotiate you need the power of the electorate in the form of a large number of votes. I will be asking for such in the elections in October. Sometimes I hear opinions that nobody can change Poland. But the truth is that evil comes when good people do nothing to oppose it. You cannot be a passive observer all your life!." Ultimately Tymiński won 12.71% (18,052) of the vote in his district, failing to gain a seat. The party's other candidate, Zbigniew Adamczyk, also failed to win a seat, winning 4.78% (7750) of the district's popular vote. Political commentators expressed astonishment at Tymiński candidacy on behalf of the party, remarking that he "has thus come a long way from being a globetrotting businessman to becoming a promoter of neo-slavism." In the
2025 Polish presidential election, the party submitted its leader, Włodzimierz Rynkowski, as the presidential candidate. His notice was accepted by the
National Electoral Commission on 18 February 2025. However, in order to be included on the election ballot, a presidential candidate must gather at least 100,000 signatures by 4 April, 6 weeks before the election. == Ideology ==
