EXPLANATIONS BELOW
Concept note-1: -When World War I began in July 1914, Italy was a partner in the Triple Alliance with Germany and Austria-Hungary, but decided to remain neutral. However, a strong sentiment existed within the general population and political factions to go to war against Austria-Hungary, Italy’s historical enemy.
Concept note-2: -Triple Alliance, secret agreement between Germany, Austria-Hungary, and Italy formed in May 1882 and renewed periodically until World War I. Germany and Austria-Hungary had been closely allied since 1879. Italy sought their support against France shortly after losing North African ambitions to the French.
Concept note-3: -The Triple Alliance was a military alliance (agreement to fight together) between Germany, Austria-Hungary, and Italy, that lasted from 1880 until the start of World War I in 1914. The three countries promised to help each other if another country attacked them.
Concept note-4: -One alliance included Germany, Austria-Hungary and Italy, called the Triple Alliance. Opposing them was the Triple Entente of France, Russia and England. These complex tensions finally exploded into war.
Concept note-5: -The Triple Entente between Britain, France, and Russia is often compared to the Triple Alliance between Germany, Austria–Hungary and Italy, but historians caution against that comparison as simplistic.
