While Jamaican émigré, New Negro author Claude McKay’s desired reading public by the mid-1920s became and remained the general American readership, at various moments during the (Long) Harlem Renaissance he enjoyed a diverse if limited reception. After early attention in Jamaica as the British Crown Colony’s first Black poet to publish a collection of verse, McKay eventually gained a measure of notice among North American politically progressive poetry enthusiasts, and then at various stages of his career gathered interest among British, French, Pan-African, and even Russian readerships. In the late 1920s, when McKay’s novel Home to Harlem became a bestseller, the New Negro author believed his star was finally rising with the broad spectrum of US readers, but the novel’s popularity was momentary, and the author’s glory transpired to be fleeting. In his lifetime, McKay never again realized the level of popular American readership he sought. During the early 1920s, the concept of an emergent, transnational American identity forged McKay’s aesthetic and accordingly his ambition to reach a US public. By the late 1930s, however, McKay rejected the idea that organized leftist politics was invested in aiding the struggling Black masses. Around the same period, he abandoned his former unique vision of a transnational America.
