Pasolini planned to extend the work of the Academiuta to the literature of other Romance languages, and met exiled Catalan poet Carles Cardó. He took part in several demonstrations after joining the PCI. In May 1949, he attended the Peace Congress in Paris. Observing the struggles of workers and peasants, and watching the clashes of protesters with Italian police, he began to conceive his first novel. During this period, while holding a position as a teacher in a secondary school, he stood out in the local Communist Party section as a skillful writer defying the notion that communism was contrary to Christian values, even though Pope Pius XII had excommunicated communist sympathisers from the Roman Catholic Church. Local Christian Democrats took notice. In the summer of 1949, Pasolini was told by a priest to renounce politics or lose his teaching position. Similarly, after some posters were put up in Udine, Giambattista Caron, a Christian Democrat deputy, warned Pasolini's cousin Nico Naldini that " should abandon communist propaganda" to prevent "pernicious reactions".
