Furthermore, the PG claimed for the suppression of the provincial governments (perceived as a redundant administrative structure) and the establishment of the parish as an official territorial tier.
This issue opens the debate in the PG, as some wanted to seek alliances with republican parties (left-wing), something which was frontally rejected by the conservatives.
Furthermore, the new conservative Spanish government halts the development of the Statute of Autonomy, bans PG's newspaper A Nosa Terra, and relocates Castelao and Bóveda far from Galicia (they were civil servants).
Hence, the PG presented five Galicianist candidates to the Spanish general election of 1936, namely: Castelao, Bóveda, Xerardo Álvarez Gallego, Ramón Suárez Picallo and Antón Villar Ponte.
Following the revolt of general Francisco Franco in July 1936, and the start of the Spanish Civil War, normal political life comes to an end.
Some of them are captured and executed, such as Johán Carballeira, Ánxel Casal, Manuel Lustres Rivas, Camilo Díaz Baliño, Víctor Casas or one of the main leaders of the party, Alexandre Bóveda.
In 1937 the PG establishes a delegation in Barcelona, still a republican area, and publishes the magazine Nova Galicia between April 1937 and July 1938.
Castelao and Suárez Picallo call for the unity of all democratic forces in Spain to preserve the Republic, while maintaining the Galicianist ideals.
The PG appeared in the underground in July 1943, when 19 members meet in Coruxo and decide to form a temporary executive committee, including Manuel Gómez Román, Otero Pedrayo and Plácido Castro.
In 1942, with the massive arrival or Galician expatriates to Buenos Aires (including Castelao), this same group relaunches the PG newspaper A Nosa Terra.
In 1944, Irmandade Galega, with the support of Castelao, establish the Consello de Galiza, a sort of Galician government in exile.
In 1949 the PG only had a total of some 200 active militants scattered around Buenos Aires and other Argentinian cities, Montevideo (Uruguay), Mexico and Havana (Cuba).
