The Socialist International: Establishment and Cooperation

The Socialist International of 1951 inherited a tradition of cooperation among European labor and social-democratic parties, but its institutions emerged through several postwar years of experimentation. The Second World War had destroyed the basis for the Labour and Socialist International's activities. Socialists exiled in London maintained contacts through the British Labour Party, with international meetings gradually resuming after the war.

In May 1946, representatives of nineteen parties met in Clacton-on-Sea, Britain, and established an information and liaison body attached to the Labour Party Secretariat. The 1947 Antwerp conference reorganized the consultative committee into the Committee of the International Socialist Conferences, or COMISCO, with every member party represented. Information sharing and conference preparation preceded the decision to rebuild an international organization.

From June 30 to July 3, 1951, delegates met in Frankfurt, West Germany, transformed the existing international conference structure into the Socialist International and designated the meeting its First Congress. Morgan Phillips of the British Labour Party became chairman, Erich Ollenhauer of the German Social Democratic Party and French socialist Louis Lévy vice-chairmen, and Julius Braunthal secretary.

Participants included the British Labour Party, German Social Democratic Party, French Section of the Workers' International and Nordic social democrats, as well as parties from India, Japan, Canada and Uruguay and several Eastern European and Spanish parties in exile. Members were parties and related organizations; the delegation list was not a list of states entering an intergovernmental treaty.

COMISCO became the Council and its smaller committee the Bureau, while a London Secretariat maintained continuing contacts. Common institutions relied on members' consent to strengthen links and coordinate political positions, with parties retaining autonomy over domestic affairs.

Braunthal's account of the founding statutes indicates that each voting party had one vote, regardless of membership size. The Council met at least annually to coordinate policy, elect leaders, approve budgets and set dues, while the Bureau and Secretariat implemented its work. Dues were an institutional means of sustaining common bodies, but the available material does not establish total receipts for 1951; later budgets cannot substitute for that figure.

The congress adopted Aims and Tasks of Democratic Socialism, usually called the Frankfurt Declaration. It advocated free elections, opposition rights, an independent judiciary and individual freedoms, criticized capitalist inequality, and explicitly rejected one-party dictatorship and the Soviet communist political model. It also recognized that members could begin from Marxist, religious, humanist or other intellectual traditions.

Its economic program called for full employment, social security, improved income distribution and democratic control of economic power, without requiring nationalization of all means of production. Private ownership was permitted in agriculture, handicrafts and small and medium-sized enterprises. Combining common principles with several institutional paths offered diverse parties a basis for cooperation; it did not mean that all countries already followed identical policies.

Early cooperation also produced continuing publication of documents. The verified bibliography lists a report of the First Congress in 1951, Braunthal's report on activities in 1951–1952 and later published proceedings of the Second Congress. These show how bulletins, activity reports and congresses turned a one-off gathering into a continuing process.

The Second Congress met in Milan from October 17 to 21, 1952. Le Monde reported on October 23 that the congress urged the four powers occupying Germany to accelerate preparations for a conference promoting reunification through free elections under international supervision. What can be established here is the formation of a shared foreign-policy position. The congress did not conclude an agreement on behalf of governments, and its appeal cannot be treated as having already achieved reunification.

A cross-border party network did not eliminate tensions within internationalism. Drawing on Kenyan activist Joseph Murumbi's correspondence, Ismay Milford and Gerard McCann showed that Asian and African socialists soon questioned the Socialist International's commitment to decolonization. The Asian Socialist Conference, established in 1953, offered another forum for discussing and organizing anticolonial cooperation.

Murumbi used these networks to contact European socialists, seeking support while criticizing inadequate action. The Socialist International's history therefore cannot be summarized only by declarations or expanding membership. Coordinating institutions sustained dialogue, while colonial policies, domestic politics and party autonomy constrained how far common positions could go.
