Before 1989: predecessors GroenLinks was founded in 1989 as a merger of four parties that were to the
left of the
Labour Party (PvdA), a
social democratic party which has traditionally been the largest
centre-left party in the Netherlands. The founding parties were the (formerly-communist)
Communist Party of the Netherlands (CPN), the
Pacifist Socialist Party (PSP), which originated in the
peace movement, the
green-influenced
Political Party of Radicals (PPR), originally a progressive Christian party, and the
progressive Christian Evangelical People's Party. These four parties were frequently classified as "small left"; to indicate their marginal existence. In the
1972 general election, these parties won sixteen seats (out of 150); in the
1977 general election, they only won six. From that moment on, members and voters began to argue for close cooperation. From the 1980s onwards, the four parties started to cooperate in municipal and provincial elections. As fewer seats are available in these representations, a higher percentage of votes is required to gain a seat. In the
1984 European election, the PPR, CPN and PSP formed the
Green Progressive Accord that entered as one into the
European elections. They gained one seat, which rotated between the PSP and PPR. Party-members of the four parties also encountered each other in
grassroots extraparliamentary protest against
nuclear energy and
nuclear weapons. More than 80% of the members of the PSP, CPN and PPR attended at least one of the two
mass protests against the placement of nuclear weapons, which took place in 1981 and 1983. The
Evangelical People's Party was a relatively new party, founded in 1981, as a splinter group from the
Christian Democratic Appeal, the largest party of the Dutch
centre-right. During its period in parliament, 1982–1986, it had trouble positioning itself between the small left parties (PSP, PPR and CPN), the PvdA and the CDA. In 1990, some opposition formed against the moderate, green course of GroenLinks. Several former PSP members united in the "Left Forum" in 1992 – they would leave the party to join former PSP-leader Van der Spek to found the
PSP'92. Similarly, former members of the CPN joined the
League of Communists in the Netherlands to found the
New Communist Party in the same year. In 1991, the congresses of the four founding parties (PSP, PPR, CPN and EVP) decided to officially abolish their parties. In 1992, party leader
Ria Beckers left the
House of Representatives because she wanted more private time. Peter Lankhorst replaced her as chair ad interim, but he announced that he would not take part in the internal elections.
1994–2002: opposition during the purple cabinets Before the
general election of 1994, GroenLinks organised an internal election on the party's political leadership. Two duos entered:
Ina Brouwer (former CPN) combined with
Mohammed Rabbae (independent), while
Paul Rosenmöller (independent) formed a combination with
Leoni Sipkes (former PSP); there were also five individual candidates, including
Wim de Boer (former chair of the PPR and member of the
Senate),
Herman Meijer (former CPN, future chair of the party) and
Ineke van Gent (former PSP and future MP). Rosenmöller set out a new strategy: GroenLinks should offer alternatives instead of only rejecting the proposals made by the government. In the
1998 general election, GroenLinks more than doubled its seats to eleven. The charisma of "unofficial leader" Rosenmöller played an important role in this. In February 2001,
Roel van Duijn and a few former members of
The Greens joined GroenLinks. Later, she apologised on public television and claimed she suffered from
post-traumatic stress disorder. In the same year, the parliamentary party supported the
invasion of Afghanistan after the
terrorist attacks of September 11. This invasion led to great upheaval within the party. Several former PSP members within the House of Representatives parliamentary party began to openly speak out their doubts about the intervention. Under pressure of internal opposition, led by former PSP members and the party's youth organisation
DWARS, the parliamentary party changed its position: the attacks should be cancelled. Before and after the elections serious threats were made against Rosenmöller, his wife and his children. These events caused considerable stress for Rosenmöller. GroenLinks lost one seat in the election, although it had gained more votes than in the 1998 elections. Before the
2003 general election Rosenmöller left parliament, citing the ongoing threats against his life and those of his family as the main reason. He was replaced as chair of the parliamentary party and top candidate by
Femke Halsema. She was unable to keep ten seats and lost two. When she returned to parliament, Halsema started a discussion about the
principles of her party. She emphasised individual freedom,
tolerance, self-realisation and
emancipation. In one interview she called her party "the last liberal party of the Netherlands". This led to considerable attention of media and other observers, which speculated about an ideological change. During the congress of February 2007 the party board was ordered to organise a party-wide discussion about the party's principles. During the European Elections congress of 2004, the candidacy committee proposed that the chair of the GroenLinks delegation,
Joost Lagendijk, should become the party's
lead candidate in those elections. A group of members, led by Senator Leo Platvoet submitted a motion "We want to choose". They wanted a serious choice for such an important office. The party's board announced a new electoral procedure. During the congress
Kathalijne Buitenweg, an MEP and candidate, announced wish to be considered for the position of top candidate. She narrowly won the elections from Lagendijk. This came as a great surprise to all. Especially for Buitenweg who had not written an acceptance speech and read out Lagendijk's. In November 2005, the party board asked Senator Sam Pormes to give up his seat. Continuing rumours about his involvement with guerrilla-training in
Yemen in the 1970s and the 1977 train hijacking by
Moluccan youth and allegations of
welfare fraud were harmful for the party, or at least so the party board claimed. When Pormes refused to step down, the party board threatened to expel him. Pormes fought this decision. The party council of March 2006 sided with Pormes. Party chair Herman Meijer felt forced to resign. He was succeeded by Henk Nijhof who was chosen by the party council in May 2006. In November 2006 Pormes left the Senate, he was replaced by
Goos Minderman. In the
2006 Dutch municipal election, the party stayed relatively stable, losing only a few seats. After the elections GroenLinks took part in 75 local executives, including
Amsterdam where MP
Marijke Vos became an alderwoman. He was replaced by
Jolande Sap. In 2008, MEPs
Joost Lagendijk and
Kathalijne Buitenweg announced that they would not seek a new term in the European Parliament. The party had to elect a new
lead candidate for the
2009 European elections. There were five candidates for this position:
Amsterdam city councillor Judith Sargentini, former MEP
Alexander de Roo, senator
Tineke Strik, environmental researcher
Bas Eickhout and
Niels van den Berge assistant of MEP Buitenweg. In an internal referendum Sargentini was elected. The
party congress put Eickhout on a second position on the list. On 18 April 2010, the party congress composed the list of candidates for the
2010 general election. Two sitting MPs
Ineke van Gent and
Femke Halsema were granted dispensation to stand for a fourth term. Halsema was re-elected as party leader. Van Gent was put as fifth on the party list. All of the first five candidates were sitting MPs and four were women. Their other high newcomers were former Greenpeace director
Liesbeth van Tongeren and chairman of
CNV youth
Jesse Klaver. The party won 10 seats in the election and participated in the formation talks of a Green/
Purple government. Halsema resigned as party leader when these talks failed and was succeeded by
Jolande Sap. In the
2012 general election, GroenLinks lost six seats and was left with four out of 150 seats. Following the disappointing result, Sap was forced to resign as party leader and was succeeded by
Bram van Ojik, who in turn handed his position to
Jesse Klaver in 2015. Under Klaver's leadership, GroenLinks gradually rose in polls before climbing to an all-time high of 14 seats in the
2017 general election. The party entered
coalition talks with the
People's Party for Freedom and Democracy, the
Christian Democratic Appeal and
Democrats 66, but the talks failed after Klaver demanded more refugees to be accepted. GroenLinks lost the
2021 general election, and combined with the
Labour Party during the
subsequent government formation. There have been discussions about a merger with that party; they participated in the
2023 Dutch Senate election as one. GroenLinks and the Labour Party announced in 2023 that they would also participate as one,
GroenLinks–PvdA, in the
general election of 2023, as members of both parties voted in favour of an alliance. With
Frans Timmermans as lead candidate, GroenLinks–PvdA eventually won 25 seats in the elections, gaining eight seats and becoming the largest
opposition party to the
Schoof cabinet. On 12 June 2025, members of GroenLinks voted in favour of another joint list for the
general election of 2025, as well as a merger with the Labour Party into a new party,
Progressive Netherlands, in 2026. ==Ideology and issues==
