Because of population growth, partly due to substantial immigration from other parts of Italy, new neighborhoods have been built. There were years of building speculation and of destruction of two historic districts of the city, the first in 1964 called "Piccapietra-Portoria" and the second in 1974 called "Madre di Dio" location of the house of Paganini; both events left indelible scars on the city and in the memory of citizens. In 1965 the political party Lotta Comunista was founded by Arrigo Cervetto and Lorenzo Parodi. A shipwreck in 1970 off the coast of Genoa, the SS London Valour, is the theme of a song by local minstrel Fabrizio De Andrè entitled "Parlando del Naufragio della London Valour", or "Talking about the sinking of the London Valour". In 1970 the Greek student Kostas Georgakis set himself ablaze in Matteotti Square, Genoa, as a protest against the dictatorial regime of Georgios Papadopoulos. In this period Genoa was the centre of protest movements that sometimes take the form of armed struggle. In the so-called Years of Lead, the Red Brigades formed a very active column in Genoa called October 22 Group, which in 1974 kidnapped magistrate Mario Sossi and in 1979 killed worker Guido Rossa and professor Fausto Cuocolo. In 1980 the Genoese Red Brigades group was eliminated at the hands of a special detachment under the orders of Carlo Alberto Dalla Chiesa.
