Associations that originally advocated Nordic neutrality, international peace and arbitration. The Norwegian Peace Association was founded by C. Bernhard Hanssen, the Danish Peace Association was founded by Fredrik Bajer and the Swedish Peace and Arbitration League was founded by Klas Pontus Arnoldson. The Swedish Peace Association was founded in 1911 and it was primarily its view on disarmament that separated it from the older Swedish Peace and Arbitration League. While the Peace Association considered disarmament to be a problem, the Peace and Arbitration Leage considered it to be subject of practical political work and agitation.
All of the associations organized Scandinavian peace conferences.
The nominators' first alternative was a divided prize among the three nominees, but they stated that it was up to the Nobel Committee to choose whether they should award the Swedish Peace and Arbitration League or the Swedish Peace Association as the third laureate.
The second alternative was a divided prize between the Norwegian and the Danish Peace Associations in case the Committee decided not to divide the prize among three candidates.
The nominators emphasized the candidates' efforts to promote neutrality.
