He contributed to the renewal of the Galician language.
As a politician, Díaz served as Minister of State in 1856, during the reign of Queen Isabella II of Spain, in a cabinet headed by Leopoldo O'Donnell, 1st Duke of Tetuan (by then Count of Lucena).
He was both a Liberal and a Catholic, belonging to the left-wing of the Moderados.
In 1863, as a member of the Liberal Union, he gave a speech on the necessity of reconciling Catholicism with Liberalism.
