Initially, the party's main objective had been to democratise the Dutch political system, but it developed a broader social liberal ideology over time. In the 1967 general election, the party won 7 out of 150 seats in the House of Representatives. No new party had ever gained that many seats before. The party was in government from 1973 to 1977, 1981 to 1982, 1994 to 2002, 2003 to 2006 and 2017 to 2021. It currently holds 24 seats in the House of Representatives, 7 seats in the Senate and 2 seats in the European Parliament.
The party is especially popular among people who hold a university degree, and its voters are mostly concentrated in larger cities and in municipalities with an above-average number of wealthy residents. The party supplies a relatively large proportion of mayors, who are appointed rather than elected. D66 is a member of the Liberal International (LI) and the Alliance of Liberals and Democrats for Europe (ALDE).
Currently, the party is led by Sigrid Kaag, who was elected party leader on 4 September 2020. Annelien Bredenoord and Sophie in 't Veld are serving as the party's parliamentary leaders in the Senate and the European Parliament respectively.
Name and logoEdit
At its foundation, the party was called Democrats '66 (Dutch: Democraten '66, abbreviated D'66). The name referred to the party's goal of radical democratisation and to the year of foundation, which was supposed to convey a modern image. In 1981, the apostrophe was dropped: the name had become a successful political brand, but the year no longer conveyed a modern image.
Democrats 66 was founded on 14 October 1966 by a group of 44 people. Its founders were described as homines novi, although 25 of the 44 had previously been members of another political party. The initiators were Hans van Mierlo, a journalist for the Algemeen Handelsblad, and Hans Gruijters, a municipal councillor in Amsterdam. Van Mierlo became the party's political leader. The foundation of the party was preceded by the "Appeal 1966" on October 10, in which the founders appealed to the people of the Netherlands to re-take their democratic institutions. The party renounced the 19th-century political ideologies, which dominated the political system and sought to end pillarisation. It called for radical democratisation of the Dutch political system, and for pragmatic and scientific policy-making.
The party participated in the 1967 general election, with Hans van Mierlo as its lijsttrekker (top candidate). The party won an unprecedented seven seats in the House of Representatives. In the 1971 general election, the party won an additional four seats and it formed a shadow cabinet with the Labour Party (PvdA) and the Political Party of Radicals (PPR). In the 1972 general election, the three parties formed a political alliance called the "Progressive Agreement" (Dutch: Progressief Akkoord; PAK) and presented the common electoral program "Turning Point '72" (Keerpunt '72).
In the election, D66 lost nearly half its seats, leaving only six. The alliance became the largest political force in the country, but it did not gain a majority. After long cabinet formation talks, the three PAK-parties formed an extra-parliamentary cabinet joined by progressive members of the Anti-Revolutionary Party (ARP) and the Catholic People's Party (KVP). The cabinet was led by Labour politician Joop den Uyl. Co-founder Hans Gruijters became Minister of Housing and Spatial Planning. After the formation talks, Van Mierlo left politics, feeling that his political position within the parliamentary party was untenable. Van Mierlo was replaced by Jan Terlouw, who became the new parliamentary leader.
In the period 1972–1974, the party lost a dramatic number of members (from 6,000 to 300) and polled very poorly in the 1974 provincial elections. The party also lost half of its senators in the 1974 Senate election. At one of the party congresses, a motion was put forth to abolish the party. A majority of the members voted in favour, but the two-thirds majority was not reached. In reaction, Terlouw started a campaign to revitalise the party, involving a membership drive and a petition to the electorate. He emphasised issues other than democratic reform and gave the party a more liberal orientation. The party doubled its membership in 1975 and won two additional seats in the 1977 general election, despite losing all its seats in the Senate in the same year.
In the 1981 general election, D66 gained 17 seats. The party formed a government with the Labour Party and the Christian Democratic Appeal (CDA), with Terlouw as Minister of Economic Affairs. The cabinet was characterised by the personal and ideological conflicts between Prime Minister Dries van Agt (CDA) and Minister of Social Affairs Joop den Uyl (PvdA). The cabinet fell nine months after it was formed, when the Labour Party left the cabinet. D66 and the CDA continued to govern in a caretaker government. In the subsequent 1982 general election, D66 lost two-thirds of its support, and was left with only 6 seats. After the election, Terlouw left politics and was replaced by Maarten Engwirda. The party was confined to opposition.
In 1986, Van Mierlo returned to politics. He emphasised democratic reform as the core issue of the party and wanted to end the polarisation between the Labour Party and the People's Party for Freedom and Democracy (VVD), so that it would be possible to form a government without the CDA. He led the party in the 1986 general election and won 9 seats. In the 1989 election, the party won 12 seats and was asked to join the formation talks of a CDA–PvdA–D66 coalition. While the PvdA preferred to form a government with D66, the CDA did not. Ultimately, D66 was excluded from the coalition, because it was not necessary to include them to reach a majority in parliament.
Despite being in opposition, D66 adopted a constructive approach towards the government. They were rewarded for this in the 1994 general election, in which the party doubled its number of seats to 24. D66 was able to form its preferred coalition: the "purple government", which included both the social democratic PvdA and the conservative liberal VVD. Van Mierlo was appointed Minister of Foreign Affairs. As advocated by D66, the first Kok cabinet initiated progressive legislation, such as the introduction of same-sex marriage and the legalisation of euthanasia. The moderately liberal economic policies of the cabinet were also seen as a great success.
Shortly before the 1998 general election, Van Mierlo stepped back and Minister of Health Els Borst became the new top candidate. D66 lost ten seats in the election, while its coalition partners gained ground at the cost of D66. The second Kok cabinet continued. Although D66 was technically not needed for a majority in parliament, it was seen as the glue that kept the PvdA and the VVD together. Borst stepped down as party leader and became Deputy Prime Minister and Minister of Health. Thom de Graaf led the party in the House of Representatives. From within the party, there were calls for a more explicit progressive liberal course. In 1999, a constitutional reform that would allow for referendums to be held was rejected by the Senate, because a group of VVD dissidents had voted against it. In response, D66 left the cabinet. After the subsequent formation talks, D66 returned to the cabinet in return for a temporary referendum law and directly elected mayors.
In the 2002 general election, the tide had turned against the purple government, and the right-wing populist Pim Fortuyn List (LPF) gained considerable ground. The three purple parties lost an unprecedented 43 seats. D66 was left with only 7 seats. The first Balkenende cabinet, consisting of CDA, LPF and VVD, lasted only three months. In the 2003 general election, D66 lost another seat, leaving only 6. De Graaf stepped down and was succeeded by Boris Dittrich. After long formation talks between the CDA and the PvdA failed, a second Balkenende cabinet was formed, which included the CDA, the VVD and D66.
In return for investments in environment and education, and a special Minister for Governmental Reform, D66 supported the centre-right reform cabinet and some of its more controversial legislation. In May 2005, the Senate rejected a constitutional reform that would allow a directly elected mayor. The legislation had been introduced by the second Kok cabinet, but it was unable to get a two-thirds majority because the Labour Party was opposed the electoral system proposed by Minister for Governmental Reform Thom de Graaf. De Graaf resigned, but the rest of the ministers retained their positions as D66 was promised more investment in public education and the environment. A special party congress was called to ratify this so-called "Easter Agreement" (Paasakkoord). 2,600 members (20 percent of total membership) were present and the congress was broadcast live on television. The congress agreed to remain in cabinet by a large majority. Alexander Pechtold replaced De Graaf as Minister for Governmental Reform. Laurens Jan Brinkhorst, the Minister of Economic Affairs, became Deputy Prime Minister.
In February 2006, Dittrich stepped down as parliamentary leader, because he did not agree with the government's decision to send the Dutch armed forces to the southern province of Uruzgan in Afghanistan. D66 voted against the government's proposal together with the Socialist Party and GroenLinks. Dittrich stated that the mission to send troops was not a reconstruction mission (as the government and the majority of the Dutch parliament claimed), but a military operation. Lousewies van der Laan replaced Dittrich. In May 2006, D66 polled particularly badly in the 2006 municipal elections. D66 began to lose a considerable number of members, some of whom founded deZES, another radical democratic, progressive liberal party. During a special party congress on 13 May 2006, a motion was put forth demanding the withdrawal of D66 from the cabinet, but it was rejected. In June 2006, an internal election was held in order to choose the new party leader. The election was won by Alexander Pechtold.
During the special parliamentary debate on the naturalisation process of Ayaan Hirsi Ali, D66 supported a motion of no confidence against Minister for Integration Rita Verdonk. As D66 was a junior coalition partner, this caused a crisis in the second Balkenende cabinet. The cabinet refused to remove Verdonk from her position. Lousewies van der Laan, parliamentary leader of D66, felt that the D66 faction could no longer support the cabinet and stated that the cabinet had to resign. On 3 July 2006, the two D66 ministers Alexander Pechtold and Laurens Jan Brinkhorst resigned, causing the second Balkenende cabinet to fall.
In October 2006, just before the D66 party congress and its 40th anniversary as a party, D66 founder Hans van Mierlo asked the question whether D66 still had political legitimacy. He believed that many errors were made in recent history and that only the acceptance of these errors could provide for any credibility for D66. Van Mierlo declared his support for party leader Pechtold, who in his view could provide for such credibility.
Since 2008, the party has performed quite well in the opinion polls, ranging from 10 to 26 seats, compared to only 3 seats in the House of Representatives. In the 2009 European Parliament election, the party won 11% of the votes and 3 seats, two more than in the previous election. The news programme Nova attributed this increase to the leadership of Alexander Pechtold, who was considered "the leader of the opposition" at the time. Under the leadership of Pechtold, the party has taken strong stances against the Party for Freedom (PVV) of Geert Wilders. In the 2010 general election, D66 increased its representation to 10 seats. In the 2012 general election, the party further increased its number of seats to 12. Since 2008, the party has experienced a significant increase in party membership, from 10,000 to 25,000 in 2015.
In the 2017 general election, D66 won 19 seats in the House of Representatives and formed a centre-right coalition government with the VVD, CDA and Christian Union (CU). Kajsa Ollongren was appointed second Deputy Prime Minister in the third Rutte cabinet. In October 2018, Alexander Pechtold announced his retirement from politics. He was replaced by Rob Jetten as parliamentary leader, but the position of party leader remained vacant. In September 2020, Minister for Foreign Trade and Development Cooperation Sigrid Kaag was elected the new party leader and top candidate for the 2021 general election. Despite the fact that the opinion polls had predicted D66 to lose seats, the party won 24 seats in the 2021 election, becoming the second largest party in the House of Representatives.
The ideology of D66 is a highly contested subject within the party and the question is tied to the reason for its existence. There are two currents within the party, namely the radical democrats and the progressive liberals. Although sometimes antagonistic, these two currents currently complement each other as both emphasise the self-realisation of the individual. The Radical League and the Free-thinking Democratic League, two early 20th century parties are historic exponents of these two traditions.
The first party congress emphasised radical democratisation of Dutch society and the political system. Its ideal was a two-party system. To obtain this, it wanted to reform the electoral system after the American first past the post model. The electoral reform was gradually moderated as the party now favours German-style mixed member proportional representation. In this system, a national party-list election is used to make a first-past-the-post election representative to the nationwide vote. This radical democratisation was combined with a pragmatic and anti-dogmatic attitude towards politics. Hans van Mierlo, the party's leader between 1966 and 1972 and between 1986 and 1998 and the party's figurehead, was an important exponent of this tendency within the party.
D66's progressive liberal counterpart has historically been much weaker than its radical democratic current. Under Jan Terlouw between 1972 and 1982, D66 began to emphasise new issues like the environment, public education and innovation. He called D66 a fourth current, next to social democracy, Christian democracy and the conservative liberalism of the VVD. In 1998, the group Opschudding called for a progressive liberal course for the party. In the party's manifesto adopted in 2000, the party explicitly adopted a progressive liberal image. National political reasons explain the usage of the label social liberal since the more right-wing VVD describes itself as the liberal party.
Some of the party's most important positions include:
- D66 is in favour of a mixed economy combining market economics and government intervention. D66 is also a proponent of increased flexibility in the labour market and tax cuts for the lower and middle classes.
- D66 proposes to increase government spending on education and innovation, for instance increases in teachers' salaries. D66 wants the education sector to be deregulated and introduce more competition in the sector.
- The environment is an important issue for the party. D66 favours a carbon price and more investment in sustainable energy to combat global warming, but opposes the right to hunt and sees hunting only as last resort for wildlife damage control.
- D66 is a socially liberal party. The first Kok cabinet in which it participated introduced several liberal reforms in the past, such as the legalisation of euthanasia, same-sex marriage and prostitution.
- D66 is a proponent of democratic reform. It favours electoral reforms such as a binding referendum, abolition of the Senate and direct election of prime ministers and mayors.
- D66 favours a Federal Europe and more European cooperation on issues such as the environment, immigration policy and foreign policy.
Although supporters of political parties are no longer fixed and election results fluctuate, D66 is overall strong and concentrated in the Randstad conurbation, while also getting its votes in and around university towns. In the 2014 municipal elections, D66 became the largest party in many major cities including Amsterdam, The Hague, Utrecht, Tilburg, Groningen, Enschede, Apeldoorn, Haarlem, Amersfoort and Arnhem.

The youth wing of D66 is called the Young Democrats (Dutch: Jonge Democraten, abbreviated JD). It has produced several prominent active members of D66, such as former MP Boris van der Ham. The JD is a member of European Liberal Youth and the International Federation of Liberal Youth.
D66 is a co-founder of the Netherlands Institute for Multiparty Democracy, a democracy assistance organisation of seven Dutch political parties. The Hans van Mierlo Foundation is the party's policy institute.
D66 is a member of the Liberal International and of the Alliance of Liberals and Democrats for Europe (ALDE). D66 joined the Liberal and Democratic Reformists (LDR) group in 1989. It became a full member of the European Liberal Democrat and Reform Party (ELDR) in 1994 and a full member of the Liberal International in 1986.
Relationships to other partiesEdit
In recent elections, political commentators have positioned D66 at the centre of the political spectrum. This offers the party a lot of possibilities for co-operation with other parties in the Dutch political landscape. Historically, D66 has often co-operated in cabinets with the Labour Party (PvdA). They were in four cabinets together (Den Uyl, Van Agt II, Kok I and Kok II), and formed a shadow cabinet in the early seventies. However, there have been heavy tensions between D66 and the PvdA on three occasions: in 1981, when D66 decided to continue to govern with the Christian Democratic Appeal (CDA) after the PvdA had left the first Van Agt cabinet; in 1989, when the PvdA formed the third Lubbers cabinet without D66; and in 2003, when D66 joined the second Balkenende cabinet.
Ideologically, the social liberal D66 is linked to People's Party for Freedom and Democracy (VVD), although VVD is considered a party of conservative liberalism. This resulted in four coalition governments (Kok I, Kok II, Balkenende II and Rutte III). Both D66 and the VVD are members of the Alliance of Liberals and Democrats for Europe (ALDE) and their respective members in the European Parliament are part of the Renew Europe group.
