During 1945 when the II World War concluded , leaving like balance: 54 millions dead, 90 million wounded, 28 million invalids and 4 000 million dollars in destroyed values. But, immediately, the imperialists unleashed the cold war.

In this context of certain taking of conscience about the problems that affected humanity soon after the end of the II World War, a meeting of the intellectuals of the world was held in the Polish city of Wroclaw in 1948, who made a call exhorting to prevent that events like those that caused the war didn't repeat again. As an initiative of this meeting the First World Congress of Peace followers was summoned April, 1949, in Paris.

2 000 delegates from 72 countries participated in the Congress, among the great personalities who attended were: the eminent French scientist Frederic Joliot Curie, Nobel Prize of Chemistry who presided over the Congress, the Spanish painter Pablo Picasso, the North American singer Paul Robeson and the Chilean poet Pablo Neruda, among others. More than 250 delegates, who could not obtain the French visa, celebrated part of the Congress in Prague. A resolution of the Congress instituted the creation of the World Committee Peace Followers. This text invited to form, in all the countries, committees for peace. Cuba had a worthy representation in the First Congress. With the World Peace Council, constituted in the Second Congress held in November 1950 in Warsaw, Poland, the movement was given flexible structures that facilitated the incorporation of all forces wishing to be represented.

The repercussion of the First Congress felt itself immediately in our country. The previous mobilization to the Congress in Paris, to send 12 delegates, joined powerful popular forces, which began to work for the convocation of a National Congress for Peace and Democracy."

Those who were summoned to this Congress were men and women of the more dissimilar origins and ideologies: young people of the University Students Federation (FEU), of the Juvenile Organizations noted artists and intellectuals, the Democratic Federation of Women (FDM) that worked under the slogan of having registered by peace workers from the Power Station of Workers from Cuba (CTC), peasants, Masonic and religious institutions, etc.

The National Congress for Peace and Democracy took place in Havana on August 6 - 8 1949, in homage to the IV anniversary of the victims of the genocide of Hiroshima and Nagasaki, delegates from all the corners of the country attended it. It is good to remember that, this was not conceived as a meeting of eminent figures, but as a movement of deep popular roots that started up from factories, schools, sugar cane colonies and regions of cultivations, joining the whole country, without distinctions of credos neither skin colors, in the effort to safeguard peace.

The inauguration of the great event took place in the Amphitheater of Calixto García hospital and the opening speech was by the eminent Cuban wise Don Fernando Ortíz, whose beautiful words captured the aspirations of peace of the Cuban people.

2 500 delegates were present. The closing of the important event took place in the theater " Auditorium ", on August 8, the Congress chose the executive of what was then denominated Standing Committee for the Defense of Peace and Democracy."

Numerous were the tasks carried out by the Standing Committee in those difficult moments, but, for their importance, we will refer to the most outstanding ones.

In the first place it is necessary to point out the gathering of signatures in support of the First Call of Estocolmo, banning the atomic bomb, under the Call 786 778 signatures were subscribed. If we take into account the number of inhabitants of our country in those moments and to the hostile government's attitude, we can give this figure like an outstanding achievement, since; it constituted likewise a high percentage in connection with other countries of the American Continent.

In the second place, there is another fact that emphasized the role carried out by the Standing Committee in favor of peace, during the difficult years of the "cold war". In 1950, the United States invades Korea, unleashing a cruel and unjust war. Under the motto Hands outside Korea thousands of signatures were obtained that consigned their rejection to that war, at the same time they opposed that the armies of the countries marionettes of Latin America participated in this war; this whole work was carried out under the most terrible persecution.

Already on September 1949, the young Standing Committee, participated with 57 delegates coming from the most diverse sectors, in the Congress of Mexico where it was clear definitively the position of the Cuban people regarding the problems of peace, sovereignty and integrity of the peoples.

Starting from 1959, in the call to the 1st National Conference for Peace, they suggested to change the name and the institution was denominated the Cuban Movement for Peace and Sovereignty of the Peoples.

The Cuban Movement for Peace and Sovereignty of the Peoples has been headquarters of events of regional and continental character and, meetings of the Bureau of the Presidency of the World Peace Council, having on those occasions the participation of delegates from numerous countries of all continents, organizations for peace and personalities of international importance.
