He was one of the founders and key member of the Partido Galeguista (Galicianist Party), origin of contemporary Galician nationalism.

He was offered a post in the Spanish capital by José Calvo Sotelo, but Bóveda opted for moving back to Galicia, where he worked at the delegation of the ministry in Ourense.

In 1928 and 1929 he is awarded with two professional grants from the provincial government to travel to Barcelona and the Basque Country in order to further study the functioning of credit unions.

In fact, Castelao and other members of the Partido Galeguista (Galicianist Party) stated that Bóveda was the "motor" behind the whole process.

However, 1936 was also the year of the July coup and the consequent start of the Spanish Civil War, eventually won by the Nationalist faction.

Alexandre Bóveda was captured on July 20, accused of treason to Spain because of his Galician nationalist ideals, and sentenced to death.
