The International Lenin Peace Prize was a Soviet Union award named in honor of Vladimir Lenin. It was awarded by a panel appointed by the Soviet government, to notable individuals whom the panel indicated had "strengthened peace among comrades". It was founded as the International Stalin Prize for Strengthening Peace Among Peoples, but was renamed the International Lenin Prize for Strengthening Peace Among Peoples as a result of de-Stalinization. Unlike the Nobel Prize, the Lenin Peace Prize was usually awarded to several people a year rather than to just one individual. The prize was mainly awarded to prominent Communists and supporters of the Soviet Union who were not Soviet citizens. Notable recipients include W. E. B. Du Bois, Fidel Castro, Lázaro Cárdenas, Salvador Allende, Mikis Theodorakis, Seán MacBride, Angela Davis, Pablo Picasso, Oscar Niemeyer, Faiz Ahmad Faiz, Abdul Sattar Edhi, Funmilayo Ransome-Kuti, CV Raman and Nelson Mandela.

Lázaro Cárdenas del Río was a Mexican army officer and politician who served as president of Mexico from 1934 to 1940. Previously, he served as a general in the Constitutional Army during the Mexican Revolution and as Governor of Michoacán and President of the Institutional Revolutionary Party. He later served as the Secretary of National Defence. During his presidency, which is considered the end of the Maximato, he implemented massive land reform programs, led the expropriation of the country's oil industry, and implemented many left-leaning reforms.
