The Social Democratic Workers' Party (Dutch: Sociaal-Democratische Arbeiderspartij, SDAP) was a socialist political party in the Netherlands existing from 1894 to 1946. Originating from a split in the prior Social Democratic League, the party was a predecessor of the current social democratic Labour Party.
History
1893–1904
The SDAP was founded by members of the

The party was founded in Zwolle in 1894. The party programme was a literal translation of the Erfurt Program of the Social Democratic Party of Germany (SPD). Both parties believed in an imminent revolution which would make an end to suffering and inequality between classes and between men and women. The parliamentary work was only seen as a means to help the workers before the revolution would set off.
In its first years, the SDAP was a small party, searching for the best way to organise itself. It received a lot of financial and organisational support from the German SPD. In 1894, the International recognised the SDAP as the labour party. The SDAP was open for other socialist organisations, such as trade unions to associate themselves with the party.
In 1896, Cornélie Huygens became the first female member of the SDAP, and the first woman in the Netherlands to be a member of a political party. She was known as the "Red Lady".[2]

In the 1901 general election, the SDAP performed particularly well; it tripled its seats to six, the Liberal cabinet which the socialists supported lost its majority. The Coalition cabinet, composed of the Protestant Anti-Revolutionary Party and the Catholic General League, ignored the Socialists. After the election victory the party's power in the socialist pillar began to rise. In a massive reorganisation, the associated socialist organisations had to integrate with the party's branches.

1903–1919
In January 1903, a large
Initially, the SDAP supported the strike, hoping it would spark a socialist revolution. But in reaction to the government legislation, moderate party members, including Troelstra, turned against the strikes. This led to a controversy between
The strike ended the cooperation of socialist unions with confessional unions and the social democratic SDAP and anarchists of other organisations. The strike however did not only lead to breaches. The trade unions were prepared to unite and work together with the SDAP. The Dutch Confederation of Trade Unions (NVV) was founded in 1905 by Henri Polak.
After the railway strike, the conflict between
On the eve of the 1905 general election, the revisionists won a crucial victory. The party decided to support liberal candidates who were in favour of universal suffrage. The party gained one seat, meaning it held seven seats, and supported the liberal minority De Meester cabinet.
Many members of the SDAP were irritated by the behaviour of the orthodox Marxists who were continuously denouncing moderates. Troelstra openly attacked the orthodox Marxists and the party congress in a formal resolution declared to oppose all labelling opportunists and revisionists. The orthodox Marxist chairman Pieter Lodewijk Tak resigned and was succeeded by Willem Vliegen. Tak also lost control of Het Volk to Vliegen.
In 1907, a group of orthodox Marxists around David Wijnkoop founded the magazine De Tribune, which attacked the revisionist leadership of the SDAP. Troelstra and other leaders removed him and his associates from the party ranks in 1909. Wijnkoop founded the orthodox Marxist Social Democratic Party (SDP) the same year. The SDP later became the Communist Party of Holland. This was one of the first splits within the European labour movement.
In the 1909 general election, the SDAP held on to its seven seats, but their liberal allies lost many seats to the Coalition parties, who won a majority of sixty seats. In the knowledge that they could not accomplish anything in parliament, the SDAP focused on the extra-parliamentary movement for universal suffrage, for both men and women, regardless of class.

The party's original strategy was to organise mass strikes for universal suffrage. But the socialist union NVV feared reprisals from employers, so the SDAP decided to start a
During this time, the
In the 1913 general election, the SDAP more than doubled its seats to 15. As a serious force in parliament, the SDAP was asked to participate in government by the liberal formateur, and was offered three ministerial posts. The SDAP, even the reformist Troelstra, refused government participation, because the party acknowledged one of its major ideals, national disarmament, could not be realised. Instead of an unstable minority government, an extra-parliamentary cabinet was formed, comprising liberal and non-partisan ministers. The cabinet intended to realise socialist demands, like universal suffrage, the state pension and the eight-hour working day.
After the 1913 municipal elections, however, the SDAP did accept government responsibility in Zaandam and Amsterdam, forming municipal executives with the liberals.
After World War I had broken out, the SDAP supported the Dutch policy of armed neutrality. This support was welcomed by the leaders of the other parties but not by many SDAP members. In 1915, a special conference declared that the SDAP only supported the government temporarily and the support could be withdrawn, thus preventing another party-wide conflict.
During the war, the Allies blockaded the Dutch ports, which in turn led to an enormous lack of food; riots broke out in the major cities. The SDAP supported the government actions against these riots. Many of the protesters were furious about the SDAP and changed allegiance to the Social Democratic Party.
Meanwhile, the political system was in revision. A constitutional reform enabling universal suffrage was prepared by the liberal cabinet. In order to realise this change a two-thirds majority was necessary. This practically meant that all major parties, including the Coalition parties needed to agree with the change. The Coalition parties would consent to the change, but only if confessional schools would be granted finances equal to the public schools and if universal suffrage was not extended to women.

The SDAP was especially critical of the second demand. On 17 September 1916, it organised a mass rally with 40,000 demonstrators, demanding female suffrage. In the end, however, the party consented with the changes the confessional parties demanded. With some changes, women were granted the right to be elected and women's suffrage was deconstitutionalised, meaning that only a normal majority was necessary to implement the change. In 1919, the left-liberal Henri Marchant initiated a bill to implement female suffrage, and in 1922 the first election with real universal suffrage was held.
In

Troelstra's mistake, the SDAP's reluctance to form a socialist/liberal government in 1913 and the electoral strength of the confessional parties prevented the SDAP's participation in government until 1939.
The SDAP won in the 1919 municipal elections, and socialist-supported municipal executives were formed in many cities.
In 1919, many socialist demands (universal suffrage, the eight hour workday and state pensions) were implemented. The party began to shift their focus away from the revolution and towards the direct improvement of the position of the working class.

1919–1946
Between 1919 and 1939, the SDAP got increasingly more seats but were kept out of government by a confessional majority; in 1926, Roman Catholic State Party leader, Wiel Nolens said that the confessionals would only govern with the socialists in a case of extreme necessity.
During the 1930s, the SDAP began to moderate its policies. It removed the demand of national disarmament in 1934, and became less republican, for instance sending a telegram with felicitations to Queen Wilhelmina in 1938 after her daughter, princess
In reaction to this moderate course, a group of orthodox Marxist members, led by
This course of moderation was suddenly interrupted by the incidents surrounding the mutiny on the cruiser De Zeven Provinciën. During the mutiny, the political leadership of the SDAP announced that, although they did not support it, they could understand the motives behind the mutiny. Because of this incident the government temporarily forbade soldiers to be a member of the SDAP.
In 1939, at the dawn of World War II, prominent SDAP members were asked to participate in a national coalition, led by Protestant politician De Geer; the dawning war was the extreme necessity that allowed the SDAP to enter government. After the Netherlands was invaded by the Germans this government became the Dutch government-in-exile, in London. The SDAP first supplied two ministers (Albeda and Jan van de Tempel) and in 1944 they were joined by Jaap Burger. The SDAP was banned in 1940 by the occupying force. Many SDAP members were involved in resistance work during the war.
After World War II, there was a widespread sentiment in the Netherlands that the political system should be changed. This was called the

Relationships to other parties
Between 1897 and 1919 the SDAP supported liberal politicians, who were in favour of universal suffrage, in some districts. Several liberal minority governments were supported by the socialists. These relations deteriorated after the SDAPs unwillingness to participate in socialist/liberal cabinet in 1913 and Troelstra's mistake (in 1918). Furthermore, universal suffrage, a goal which united the liberals and the socialists was granted in 1918.
The relations between the SDAP and the confessional parties was particularly bad. The confessional parties saw socialism as an atheist ideology. This prevented SDAP government participation until 1939. Following the 1919 election some Christian socialist parties entered parliament which advocated stronger cooperation between the SDAP and the confessional parties. These calls were ignored by the confessional parties.
The SDAP was in constant state of cold war with the communist party
The SDAP also had good relations with the
