p The idea of publishing a book about the international solidarity with the Spanish people in the thirties was advanced in July 1966 at the Berlin international meeting of veterans of the Spanish national-revolutionary war and former international brigaders. An International Editorial Board was set up for the purpose. At its meeting in Moscow on January 10 through 19, 1970, the Board discussed and approved for publication the materials presented by a number of national organisations of Spanish war veterans.

p Naturally, the collection could not contain material on all the national contingents that took part in the struggle in Spain. Nevertheless, the contribution made by anti-fascists from the countries listed in the book was decisive both for the movement of solidarity with the Spanish Republic and for the organisation of International Brigades.

p The International Editorial Board was greatly helped in its work by Dolores Ibarruri and other editors of the monumental study The War and Revolution in Spain 1936-1939; by International Brigade veterans Franz Dahlem (GDR), Franciszek Ksiezarczyk (Poland), Karlo Lukanov (Bulgaria), and Valter Roman ( Rumania).

p The articles on the solidarity movement with Republican Spain were prepared by the following organisations of veterans of the movement and of the anti-fascist war of the Spanish people in 1936-1939 (the authors’ names are given in brackets): 

p A group of Argentinian volunteers in the Spanish People’s Army (a group of authors);
