Ivan Meredith Nurse was born in the British colony of Trinidad in 1902 and moved to the United States in 1924 to pursue his studies. He became an anti-racist militant in the Jim Crow s United States, joined the international communist movement, and changed his name to George Padmore in 1929. By 1930, he was already one of the best-known black communists in the service of Moscow, responsible for coordinating a black workers international from Hamburg, Germany. In 1934, he broke with the Comintern and Joseph Stalin, although he continued as a Marxist and defender of the Soviet state model. Between 1935 and 1957, he was the great articulator of anti-colonial and anti-imperial resistance from London. Padmore was a leading Pan-Africanist thinker, organizer of the Fifth Pan-African Congress of Manchester in 1945, and architect of the Gold Coast s independence in 1957. The analysis of George Padmore s trajectory and political thinking allow to evidenciate the experience of the Back Diaspora and allows us to understand the systematization of a Pan-African ideology centered on the African masses, the emancipation of the African continent and the building of African Socialist States. George Padmore wrote articles in newspapers of various colonial territories, but also in journals of the metropolis. He also produced works that sought to guide the anti-imperial movement and anticolonial struggles. This thesis intends to present this Silent Hero in its linguistic context, along with other black intellectuals such as, W.E.B. Du Bois, Claude McKay, C.L.R. James, Kwame Nkrumah, in order to evidence the Pan-African political vocabulary of the first half of the twentieth century.
