De Castro was born in Guarda, on 9 November 1878. He was part of the Constitutional junta that governed Portugal in 1915. He later served as Governor-General of Mozambique between 1915 and 1918. He was a prominent participant in the attempted coup of 11 January 1919 which took place after the assassination of Sidónio Pais.
