Mussolini used his new newspaper "Il Popolo d'Italia" and his strong oratorical skills to urge nationalists and patriotic revolutionary leftists to support Italy's entry into the war to gain back Italian populated territories from Austria-Hungary, by saying "enough of Libya, and on to Trento and Trieste". Mussolini claimed that it was in the interests of socialists to join the war to tear down the aristocratic Hohenzollern dynasty of Germany which he claimed was the enemy of all European workers. Mussolini and other nationalists warned the Italian government that Italy must join the war or face revolution and called for violence against pacifists and neutralists. Left-wing nationalism also erupted in Southern Italy as socialist and nationalist Giuseppe De Felice Giuffrida saw joining the war as essential to relieving southern Italy of the rising cost of bread which had caused riots in the south, and advocated a "war of revolution".
