Question: What Fascist regime imprisoned the a famous Italian noe-Marxist?

Context paragraphs:
Antonio Gramsci: Antonio Francesco Gramsci (] ,    ; 22 January 1891 – 27 April 1937) was an Italian Marxist theorist and politician.  He wrote on political theory, sociology and linguistics.  He attempted to break from the economic determinism of traditional Marxist thought and so is considered a key neo-Marxist.  He was a founding member and one-time leader of the Communist Party of Italy and was imprisoned by Benito Mussolini's Fascist regime.

Revisionist Maximalism: Revisionist Maximalism was a short-term Jewish fascist ideology which was part of the Brit HaBirionim faction of the Zionist Revisionist Movement (ZRM) created by Abba Ahimeir.  Revisionist Maximalists strongly supported the Italian fascist regime of Benito Mussolini and wanted the creation of an Israel based on fascist principles.  The Revisionist Maximalists became the largest faction in the ZRM in 1930 but collapsed in support in 1933 after Ahimeir's controversial decision to support Nazi Germany due to its fascist and anti-communist stances, while opposing their antisemitic policies.  After facing outrage, Ahimeir reversed his position shortly afterwards, with Revisionist Maximalists attacking German consulates, but support for Ahimeir did not recover and the Revisionist Maximalists collapsed until they were recreated in 1938 under new leadership.

Tropical fascism: In African political science, tropical fascism is a type of post-colonial state which is either considered fascist or is seen to have strong fascist tendencies.  Gnassingbé Eyadéma the dictator of Togo from 1967 to 2005 has been considered an example of tropical fascism in Africa.  The Hutu Power movement, a Hutu ultranationalist and supremacist movement that organized and committed the Rwandan Genocide aimed at exterminating the Tutsi people of Rwanda, has been regarded as a prominent example of tropical fascism in Africa.  The Khmer Rouge regime in Cambodia has been called a tropical fascist regime in spite of the regime's official commitment to communism particularly by opponents of the regime.

Fall of the Fascist regime in Italy: The Fall of the Fascist regime in Italy, also known in Italy as 25 Luglio ("Venticinque Luglio", ] ; Italian for "25 July") denotes the events in spring and summer 1943 in Italy, which culminated with the meeting of the Grand Council of Fascism on 24–25 July 1943, the passing of a vote of no confidence against Benito Mussolini, and the change of the Italian government.  These events were the result of parallel plots led respectively by Count Dino Grandi and King Victor Emmanuel III: their final outcome was the fall from power of the Italian Fascist government after 21 years and the arrest of Mussolini.

Telefoni Bianchi: Telefoni Bianchi (] ; "white telephones") films were made in Italy in the 1930s in imitation of American comedies of the time.  For example, there would be expensive Art Deco sets featuring white telephones (status symbol of bourgeois wealth and generally unavailable to the movie-going public), and children would have Shirley Temple curls.  The films tended to be socially conservative, promoting family values, respect for authority, a rigid class hierarchy, and country life, all stances perfectly in line with the ideology of the fascist regime.  The genre is also referred by modern film critics as "Hungarian style comedies", because they were often adaptation of stage plays of Hungarian authors (a popular source material also for Hollywood productions of the time).  In fact, to avoid the limitations imposed by the censure of the fascist authorities, when potentially controversial topics were addressed in the plot (for instance divorce, at the time illegal in Italy, or adultery, a punishable offence by the contemporary Italian law) the action was often set in various, and sometimes imaginary, Eastern European countries, but always with Italian protagonists.

Altiero Spinelli: Spinelli was born in Rome, and joined the Italian Communist Party (PCI) at an early age in order to oppose the regime of Benito Mussolini's National Fascist Party.  Following his entry into radical journalism, he was arrested in 1927 and spent ten years in prison and a further six in confinement.  During the war he was interned on the island of Ventotene (in the Gulf of Gaeta) along with some eight hundred other political opponents of the regime.  During those years, he broke with the Italian Communist Party over Stalin's purges (resulting in him being ostracised by many of the other prisoners), but refused to compromise with the fascist regime, despite offers of early release.

Tirrenia Studios: The Tirrenia Studios (also known at one point as the Pisorno Studios) are a film studio complex located in the Italian coastal town of Tirrenia in Tuscany.  The studios were constructed between 1933-1934 and intended, along with the Fert Studios in Turin, to provide northern competition to the increasingly dominant Cines Studios in Rome.  Tirrenia was a new town which had grown with the support of Italy's Fascist regime.  Although Italian film production was booming following an early 1930s slump, Tirrenia quickly faced increasing competition from the large Cinecitta studios in Rome which had been opened in 1937 as part of the Fascist's attempt to centralise film production in the capital.  Nonetheless the studios continued to be used, sometimes facilitating location shooting nearby.

The Verona Trial: Il processo di Verona (internationally released as The Verona Trial) is a 1963 Italian historical drama film directed by Carlo Lizzani.  The film tells of the final phases of the Italian fascist regime, in particular the affair of the 1944 Verona trial, in which Galeazzo Ciano, Emilio De Bono and other eminent Fascist officials were sentenced to death and almost immediately executed by a shooting detachment.

Prison Notebooks: The Prison Notebooks (Italian: "Quaderni del carcere" ] ) were a series of essays written by the Italian neo-Marxist Antonio Gramsci.  Gramsci was imprisoned by the Italian Fascist regime in 1926.  The notebooks were written between 1929 and 1935, when Gramsci was released from prison on grounds of ill-health.  He died in April 1937.

Teresio Olivelli: Teresio Olivelli (7 January 1916 – 12 January 1945) was an Italian Roman Catholic soldier during World War II and part of the Italian Resistance movement to Fascism and the Nazi regime.  Olivelli graduated in law in Pavia in 1938 and went on to comment in papers on the legal and social issues of the time before he became a volunteer fighter in the Spanish Civil War and in World War II with a notable campaign fought in Russia.  The war soured his views towards the Italian fascist regime of Benito Mussolini and his time in the resistance was marked with articles in a newspaper he founded dedicated to promoting the Christian message and attempting to improve upon aspects of fascism with a more Christian message.
