Radio Renascença

Radio Renascença began in 1934 as Monsignor Manuel Lopes da Cruz's project to give the Portuguese Catholic Church its own voice on the air, an organ of Catholic Action from the start rather than a commercial venture that happened to carry religious content. Trial broadcasts began in June 1936, and by New Year's Day of 1937 the station was transmitting regularly, jointly owned by the Patriarchate of Lisbon and the Portuguese Episcopal Conference, an ownership structure it has kept, through the modern holding company Grupo Renascença Multimédia, ever since.

That continuity survived a genuine threat. Portugal's 1974 revolution did not simply end four decades of authoritarian rule, it also brought a turbulent period of nationalizations and worker takeovers across Portuguese media and industry, and in 1975, during what Portuguese history remembers as the revolutionary "Hot Summer," a workers' committee occupied Radio Renascença itself. The occupation did not last. By December 1975 the station had been returned to the Catholic Church, making Radio Renascença the only major Portuguese radio broadcaster of its era that the state, even at the height of revolutionary upheaval, never permanently took from the institution that built it.

Otelo Saraiva de Carvalho, the military officer who planned the coup that became the Carnation Revolution, needed a signal every unit could receive on an ordinary radio, at an exact moment, without anyone outside the plot understanding what they were hearing. His first choice was another José Afonso song, "Venham Mais Cinco," but the radio host helping plan the broadcast, João Paulo Diniz, talked him out of it: the song was one of the many Afonso compositions Estado Novo censors had banned as suspected Communist propaganda, and airing a banned song, on any station, at midnight, would have drawn exactly the attention the plot needed to avoid. "Grândola, Vila Morena," a 1964 tribute Afonso wrote to a working-class musical society in the Alentejo town of Grândola, had somehow escaped the censors entirely, an ordinary folk song by an artist the state watched closely.

The plan used two signals rather than one. At 22:55 on April 24, Paulo de Carvalho's Eurovision entry "E Depois do Adeus" aired on a different station, alerting officers to prepare. Then, at 00:20 on April 25, Radio Renascença played "Grândola, Vila Morena," the operational go-ahead. Within hours, Armed Forces Movement units loyal to the plot occupied Lisbon's military headquarters, airports and government buildings, and by the next day Portugal's authoritarian government had fallen, leaving a Catholic radio station's late-night broadcast of an unbanned folk song as the exact moment historians point to when the Carnation Revolution began.
