starts publishing the magazine Nós, together with Vicente Risco and Otero Pedrayo. That same year he travelled through France, the Netherlands and Germany. In 1922, he wrote the novel Un ollo de vidro and in 1924 he joined the Seminário de Estudos Galegos ("Seminar of Galician Studies") and founded the Pontevedra Polyphonic Choir; as he was an amateur musician). Two years, in 1926, he published Cousas. He travelled to Brittany in 1928 to study calvaries and publish As cruces de pedra na Bretaña. That is also the year when his only son dies at the age of 14. Political career (1930–1950) From 1930 Rodríguez Castelao's political activism intensifies even further. His life and work always revolved around politics and his Galician nationalist ideas. In his book Sempre en Galiza he states that all his works, talent and efforts would always be used for the profit of the Galician cause. In 1930, he founded the Galician Republican Federation at Lestrove Palace and participated in the meetings of the Galician Nationalist Republican Party and in the assembly for the Federal State of Galicia. The next year he published the book Nós and became the official representative of the Galicianist Party to the Cortes Generales. In 1934, he published Retrincos, Os dous de sempre and the a re-edition of Cousas. He became a member of the Royal Galician Academy in 1933, and shortly after that, in 1935, he was forced into exile by the Spanish government to the Spanish city of Badajoz, in Extremadura, where he worked as a civil servant. It was then where he began to write what would become his key work, Sempre en Galiza. In 1936 he gained a seat at the Spanish parliament, this time representing the Popular Front coalition, which included the Galicianist Party. The Spanish civil war began whilst Castelao was in Madrid presenting the results of the referendum for the Galician Statute of Autonomy, which had been approved by 98 per cent of voters, and in which Castelao had played a role, together with his personal friend Alexandre Bóveda. During the war he organised the Galician militias in collaboration with the Spanish Communist Party and declared his support to the government of the Spanish Republic. As the Nationalist troops advanced Castelao fled to Valencia - where he still had time to publish Galicia Martir and Atila en Galicia - and later moved to Barcelona. In
