Flag of the Italian Fascist National Party (Partito Nazionale Fascista). In 1926, the Fascist government attempted to have the Italian national flag redesigned by having the fasces, the symbol used by the Fascist movement, included in the flag. However, this attempt was stopped by strong opposition by Italian monarchists. Afterwards, the Fascist government raised the national tricolour flag along with a Fascist black flag in public ceremonies. (compare Denis Mack Smith: Italy and its Monarchy. Yale University Press, 1989, S. 265; Tarquinio Maiorino et al.: Il tricolore degli italiani. Storia avventurosa della nostra bandiera. Arnoldo Mondadori Editore, 2002, S. 248.)
