The period of Solidaridad Gallega ("Galician Solidarity"), the beginning of the modern Galician nationalist movement, began in 1907 and ended around the First World War. Its unsuccessful aim was to create a unified electoral coalition to eliminate caciquism and obtain Galician representation in the Cortes Generales, the parliament of Spain.
The first stage of 20th-century Galician history lasted until the dictatorship of Primo de Rivera. In this stage the Galician nationalist Irmandades da Fala ("Brothehoods of the Language") began to appear to promote the Galician language. When they began to expand, the political idea of Galicianism was popularized. Intellectuals such as Vicente Risco and Ramón Otero Pedrayo travailed in the cultural aspect of galicianism and Porteira and Lois Peña Novo in the political galicianism. They were taken over by the members of the xeración Nós ("We" generation), united around a magazine of the same name (Nós). This members of the Xeneración Nós were supported between 1920 and the Spanish Second Republic by a preoccupation about the creation of a moderated galicianism.
In the Second Republic there were two principal groups: the Autonomous Galician Republican Organization and the Partido Galeguista (Galicianist Party). This party, the PG, was a union of different ideologies with the common denominator of the Galicianism. Its members were people as Vicente Risco, Ramón Otero Pedrayo, Ramón Cabanillas, Suárez Picallo, Castelao... In 1936 the PG, to get the Galician Statute, allied with the People's Front, and as a result of this alliance the party had its first splitting. Nevertheless, the Statute was got and Castelao presented it in the Spanish Parliament a few days before the Spanish Civil War.
