Flamigni was born in Forlì on 22 October 1925. He began his political activity in 1941, as a member of a clandestine group of young anti-fascists in his hometown, and subsequently entered the Communist Party of Italy. In 1943, he was named secretary of the communist youth movement in Forlì and became a member of the party's clandestine committee in the city. He fought as partisan in the Italian resistance movement against the German occupation. In 1952, Flamigni was appointed secretary of CGIL (Italy's left-wing main trade union) in Forlì, and later he became secretary of the local section of PCI. In 1959, he was elected into the party's national central committee, and in the following year regional coordinator for Emilia-Romagna. He was also a member of the city council of Forlì from 1956 to 1960, and of the provincial council from 1960 until 1964. Flamigni was elected to the Italian Chamber of Deputies in 1968, remaining a member until 1979, when he became an Italian Senator. Flamigni worked in the Italian Parliament's commissions on the Mafia, the kidnapping of Aldo Moro, and the Propaganda Due secret lodge. He authored books on these topics.
