Background in 2023 Wagenknecht, who has been described as a prominent left-wing politician, was a member of The Left and its predecessors, such as the
Socialist Unity Party of Germany (SED) and the
Party of Democratic Socialism (PDS); her political positions are generally identified as
left-wing populist. Although she was co-leader of The Left from 2015 to 2019, conflict with other party members on topics, such as the
German refugee policy,
COVID-19 vaccination, and the
2022 Russian invasion of Ukraine, had led to speculation since 2021 that she would leave The Left and found a new political party. The success of the AfD led Wagenknecht to claim that a left-wing populist party could compete with the AfD while also respecting the
German constitution. In 2022, Sahra Wagenknecht blamed 's successive electoral failures (the party's national share of the vote having fallen from 12% in 2009 to 5% in 2021) on its emphasis on policies to combat
sexist,
racist or
homophobic discrimination, to the detriment of economic issues. She argues for the primacy of the latter, in contrast to the
intersectional approach of the party's leadership, which uses the term "
classism" to refer to the social question as a form of discrimination, in the same way as sexism or racism. In her view, the working classes no longer recognise themselves in the discourse of the left, and are turning to the far-right AfD party as a receptacle for the protest vote.
Association registration The association
BSW – Für Vernunft und Gerechtigkeit e.V., based in Karlsruhe, was entered in the association register at the district court in
Mannheim on 26 September 2023. In mid-October, over fifty members of The Left submitted an application for Wagenknecht's exclusion from the party in order to prevent her from building a new party with the resources of The Left. Members of the party and political commentators blamed the ongoing speculation about the founding of a new party and the resulting breakup of the Left for its poor results in the state elections. The Federal Executive Board of The Left passed a
resolution of incompatibility with BSW. Shortly after the press conference was announced, a fake website was registered under
www.bswpartei.de that presented itself as the official website of the party, using copyrighted imagery and Wagenknecht's office address in its imprint. Wagenknecht filed a criminal report against the website, which is now offline. It is still unclear who created it. Members of BSW in the German Bundestag want to continue working as a parliamentary group and have submitted a corresponding application to the
president of the Bundestag. When the
Wagenknecht Group was constituted in the Bundestag on 11 December 2023, Wagenknecht was elected its chair,
Klaus Ernst its deputy chair, and
Jessica Tatti its parliamentary managing director. The association also started being represented in the
Berlin House of Representatives by
Alexander King, the
Hamburg Parliament by
Metin Kaya and, the
Parliament of Rhineland-Palatinate by
Andreas Hartenfels, a former member of
Alliance 90/The Greens.
Party foundation {{Image frame|align=right|border=no|width=400|content= The party was officially founded on 8 January 2024, followed by a two hour long press conference. This formation process saw the creation of a new website and the publishing of the first party manifesto for BSW. The party also named its lead candidates for the
2024 European Parliament election in Germany and announced that it had already created a full list of candidates due to be approved at the first party conference. The
University of Potsdam developed a political test,
BSW-O-Mat (name being a reference to the
Wahl-O-Mat by the
bpb), based on the first party manifesto. The test was released on the same day as the manifesto. It was announced on 1 December 2023 that the first party conference is planned to be held on 27 January 2024. Ralph Suikat also commented at the time, that the association had thus far received an amount of donations in the seven figures, this was later clarified to be 1.4 million Euros collected during the whole of 2023. The majority (90%) of which were small donations, only €12,000 in total were donated from non-EU foreign countries, thereof €75 in total from
Russia. On 27 January 2024, the party held its first party conference and invited 450 of its founding members. The party elected its executive committee and formulated a draft program for the
2024 European Parliament election in Germany, which included criticisms of the European Union in its current form and demands for more decision-making power to the member states and significant restriction of migration to Germany. The party won six seats, and saw particular strength in eastern Germany.
Mandates and offices The ten BSW members of parliament represented in the German Bundestag were elected to parliament via the respective state lists of the Left Party. They were recognised as a parliamentary group on 2 February 2024. It bears the name
Gruppe BSW im Bundestag and had already constituted itself internally on 11 December 2023. Sahra Wagenknecht was elected chairwoman,
Klaus Ernst as deputy chairman and
Jessica Tatti as parliamentary manager. The other MPs in the group are
Amira Mohamed Ali,
Ali Al-Dailami,
Sevim Dağdelen,
Andrej Hunko,
Christian Leye,
Żaklin Nastić and
Alexander Ulrich. With
Alexander King (
Berlin House of Representatives),
Metin Kaya (
Hamburg Parliament) and
Andreas Hartenfels (
Rhineland-Palatinate State Parliament) the party is also represented in three state parliaments through defections. With the switch of
Katja Wolf to the BSW in March 2024, the party provided the mayor of the city of
Eisenach in
Thuringia until the end of June 2024, because she did not run again in the local elections in Thuringia in May 2024 and instead ran as the top candidate for the BSW in the
Thuringian state elections in September 2024. In the
2024 European Parliament election in Germany, six candidates of the BSW secured their seats and became
members of the European Parliament:
Fabio De Masi,
Thomas Geisel,
Michael von der Schulenburg,
Ruth Firmenich,
Jan-Peter Warnke and
Friedrich Pürner. The party unsuccessfully sought to form a parliamentary group in the European Parliament together with the Italian
Five Star Movement. In February 2025, Pürner resigned from the party, reducing the BSW's number of seats to five. In September 2024, Slovak
Smer began negotiations with two other parties in the
Non-Inscrits, the BSW and the Czech
Stačilo!, on establishing cooperation between left-wing conservative parties in the EU. In September 2024, the BSW achieved a double-digit share of the vote and third place in the state elections in
Saxony,
Thuringia and
Brandenburg. In
February 2025 the party fell just below the 5% threshold to win seats in the German Bundestag, and thus lost all their representation. A few weeks later they distantly failed to reach 5% in the
Hamburg state election, and lost their seat. Since December 2024, the BSW has been involved in state governments in Brandenburg (
Woidke IV Cabinet) and Thuringia (
Voigt Cabinet) for the first time.
2024 state elections in eastern Germany In September 2024, BSW faced its first large electoral test in Landtag elections in the states of
Brandenburg,
Saxony and
Thuringia. In Saxony and Thuringia, the BSW came in third place. In Brandenburg, the BSW competed with largely unknown candidates. Although 13 BSW candidates were elected to the state parliament on September 22, their names were missing from the state party's homepage before and after the election. On 11 December 2024,
Dietmar Woidke formed the
Woidke IV Cabinet in
Brandenburg and the first nationwide
red–purple coalition with the BSW was formed. In Thuringia, a
Blackberry coalition was formed.
2025 federal election The 2025 federal election was initially scheduled for September, but was moved up to 23 February following the collapse of the governing
traffic light coalition. The Bundestag was formally dissolved on 27 December. During the election campaign, the public broadcaster
ARD invited the most promising top candidates from the parties to a TV debate called the "Election Campaign Arena" on 15 February 2025, however BSW was excluded. Sahra Wagenknecht filed a constitutional complaint to ensure that the BSW was also invited. However, the courts decided that the BSW did not have a significance comparable to that of the other invited parties at that time. In the summer months of 2024, the BSW polled at over 10% of the vote, but the party ultimately received 4.9% of the vote, coming just short of the
5% threshold that would have entitled it to Bundestag seats. Wagenknecht's former party,
The Left, recorded its best result since
2017, 8.8%, following a late surge in momentum. The BSW would only outperform The Left in
Saxony-Anhalt, finishing behind The Left in all other states. After the federal election, Wagenknecht left open what the result meant for her and her party. She did not appear publicly, with the BSW's co-chair
Amira Mohamed Ali delivering the post-election press statements. Before the election, Wagenknecht had said "The election is of course also a decision about my political future. Anyone who is not in the Bundestag is no longer a relevant factor in German politics." In BSW official statement at the
federal press conference the day after the election, Sahra Wagenknecht blamed the media and the polling institute
Forsa for the failure. A "negative media campaign" had contributed to the failure of her party. In addition, she claimed that the polling outfit Forsa had always reported BSW vote shares that were too low in its poll results and had engaged in "targeted manipulation". Wagenknecht's accusations were hardly taken into account; the
DJV called them "absurd". She also stated that she sees the result "as a mandate to further develop the BSW and lead it into the Bundestag by 2029 at the latest".
Jürgen W. Falter attributed the party's defeat to "internal factional struggles and resignations", pointing to Wagenknecht's dispute with
Katja Wolf, BSW's regional chairperson in
Thuringia. The appeal for nationwide recount came after isolated recounts of polling stations in
North Rhine-Westphalia produced 1,295 additional votes for the BSW. Irregularities were found in other states as well – in
Brandenburg, post-election corrections resulted in the BSW claiming 218 more votes; corrections also had to be made in polling stations of places such as
Aachen,
Lahn-Dill-Kreis, and
Duisburg. On 13 March, the Federal Constitutional Court ruled that the appeals for a recount from BSW and voters' committees were inadmissible; the ruling noted that an election review is a matter for the Bundestag and not the Federal Constitutional Court, and is only available after the final elections results are announced. On 14 March 2025, the
Federal Returning Officer released the final results of the 2025 parliamentary election - BSW's vote margin increased to 4.981%. Compared to the preliminary results from February, the party gained 4,277 votes after isolated corrections. Following the announcement of final results, the BSW announced that it would continue to contest the election by filing an appeal to the Bundestag electoral commission, and then again to the Federal Constitutional Court if necessary. It stated its belief that a recount is necessary and that a thorough inspection could show that it crossed the 5% threshold. According to BSW, despite no irregularites being detected at first, a recount in
Marzahn-Hellersdorf still found two additional votes for the party, which would amount to 15,000 votes if extrapolated nationwide.
Internal disputes After the poor result for BSW in the German Federal election, Wagenknecht blamed BSWs participation in the government in Thuringia, accusing state party
Katja Wolf of being partly responsible for the BSW's poor performance in the federal election. Though Wolf built the largest and most successful BSW regional association in Germany, she is considered to represent a pragmatic political position, as opposed to Wagenknecht's more radical position, and under Wolf's leadership BSW is participating of the Thuringian state government with the CDU and SPD. Ultimately, Wolf would be challenged for leadership of the Thuringian BSW by
Anke Wirsing, who was backed by Wagenknecht. In April 2025, Wolf would defeat Wirsing and retain control of the Thuringian branch of the party. On 10 November 2025, Sahra Wagenknecht stepped down as the chair of the party and was replaced by the party's MEP
Fabio De Masi. However, Wagenknecht stated that she would continue to maintain an "active leadership role" in the party. On 5 January 2026, in the wake of a
coalition dispute between the SPD and BSW in
Brandenburg, Deputy Minister-President
Robert Crumbach announced he was leaving the BSW at a news conference, calling the BSW unfit for the responsibilities of governing. Minister-President
Dietmar Woidke has not made a decision whether to retain him as finance minister, though Crumbach stated his wish to do so. Crumbach, who is a former member of the SPD, has formally requested to rejoin the SPD parliamentary group, but is not rejoining the party as a member. The two other BSW ministers of the
fourth Woidke cabinet also left the party; health minister and Infrastructure minister , leaving no BSW ministers in the fourth Woidke cabinet. Crumbach was replaced as BSW state chair by
Friederike Benda. The BSW won no seats in the
2026 Baden-Württemberg state election. == Intra-party structure ==
