Context paragraphs:
Congress of Verona (1943): The Congress of Verona in November 1943 was the only congress of the Italian Republican Fascist Party, the successor of the National Fascist Party.  At the time, the Republican Fascist Party was nominally in charge of the Italian Social Republic, a small fascist state set up in Northern Italy after the Allies entered Rome.  The Salò Republic was in fact a German puppet state and most of its internal and external policies were dictated by German military commanders.  Nevertheless, Italian fascists were allowed to keep the trappings of sovereignty.  It was under these conditions that they organized the Congress of Verona, ostensibly for the purpose of charting a new political course and rejuvenating the Italian fascist movement.

H. A. Sinclair de Rochemont: Whilst studying Indology at Leiden University, he became associated with the rightist professor Gerardus Johannes Petrus Josephus Bolland (1854 - 1922).  After leaving the university in 1924, he set up the country's first fascist movement, the "Verbond van Actualisten", with Alfred Haighton.  This group had stood in the 1925 general election but managed to win only 0.08% of the vote.  Alongside this, Sinclair de Rochemont worked as a journalist for "De Vaderlander" and as a strike breaker.  In 1927, he began editing "De Bezem" (The Broom), a fascist journal aimed at the working classes and continued to publish under this name after 1930, when he split from Haighton.

He took an active role in the “interventionist left” where he “espoused an alliance between nationalism and syndicalism.”  He was one of the most influential politicians of the regime before his succumbing to tuberculosis in 1930.  He as well was one of the grand architects behind the "Great List" ("il listone") which secured the parliamentary majority in favor of the fascists.

Colonel Eric Campbell, a First World War veteran.  The New Guard declined rapidly following Lang's dismissal in May 1932, with its remaining members becoming increasingly inclined towards fascism.
