Born of a bourgeois family, Ary dos Santos soon developed several skills for poetry. At only 14, the family published some poems, against his will - (he thought the poems were not good enough). In 1943, at the age of 16, Ary saw some of his poems being selected for the Anthology of the Almeida Garrett prize. After that, Ary left his family, working on several jobs, like marketing or selling bubblegum.

His poetic work continued to develop and in 1963 he published his first book, "A Liturgia do Sangue".
1969 was the year that changed Ary's life, as he liked to say. He became a member of the Portuguese Communist Party and quickly developed his revolutionary vein.
Meanwhile, Ary participated, under a pseudonym, in the RTP Song Contest, writing the lyrics of two songs to be performed by Simone de Oliveira and Fernando Tordo.

During his career, Ary also wrote several revolutionary poems, for political intervention, about the Estado Novo regime's anti-democratic policies, the need for freedom and celebrating the post-revolutionary conquests, which led him to be called the poet of the revolution.
