Munich, Germans reacted to Italy's aggression by singing anti-Italian songs. Italy's relations with France were also in bad shape: France felt betrayed by Italy's support of Prussia in the Franco-Prussian War, opening the possibility of war erupting between the two countries. Italy's relations with the United Kingdom had also been impaired by constant Italian demands for more recognition on the international stage following the occupation of Libya and its demands that other nations accept its spheres of influence in Eastern Africa and the Mediterranean Sea. In the Mediterranean Sea, Italy's relations with the Kingdom of Greece were aggravated when Italy occupied the Greek-populated Dodecanese Islands, including Rhodes, from 1912 to 1914. The Ottoman Empire had formerly controlled these islands. Italy and Greece were also in open rivalry over the desire to occupy Albania. King Victor Emmanuel III himself was uneasy about Italy pursuing distant colonial adventures and said that Italy should prepare to take back Italian-populated land from Austria-Hungary as the "completion of the Risorgimento". This idea put Italy at odds with Austria-Hungary. A major hindrance to Italy's decision on what to do about the war was the political instability throughout Italy in 1914.

The protests that ensued became known as "Red Week" as leftists rioted and various acts of civil disobedience occurred in major cities and small towns such as seizing railway stations, cutting telephone wires and burning tax-registers. However, only two days later the strike was officially called off, though the civil strife continued. Militarist nationalists and anti-militarist leftists fought on the streets until the Italian Royal Army forcefully restored calm after using thousands of men to put down the various protesting forces. Following the invasion of Serbia by Austria-Hungary in 1914, World War I broke out. Despite Italy's official alliance with Germany and membership in the Triple Alliance, the Kingdom of Italy initially remained neutral, claiming that the Triple Alliance was only for defensive purposes. In Italy, society was divided over the war:
