Italy joined the the Allies because they thought the Allies would win. They are a very good guesser.
Italy is keen to be on the winning side in WW1. Therefore they took time to see which way the wind blew ! In 1915 they joined the Allies.
In world War I Italy joined the Allied side and was invaded by German and Austrian armies; which pushed south almost as far as Venice.
Assuming that by "Geramnies" you mean Germany's then... Germany was in the side of the "Triple Alliance". This alliance consisted of Germany, Austro-Hungary and for part of the war, Italy. However in 1915, Italy joined the side of the allies after the secret Treaty of London. They were against the allies; the "Triple entente", which consisted of Britain, France and Russia. Later, in 1917, the Americans joined the war on this side.
At the beginning of World War II, Italy was fought on the Axis Power. Later on, Italy was captured by the U.S. and forced it to surrendered. The United States installed a new pro-American government in Italy. Then, Italy joined the war the side of the Allies. So Italy counted as the Allies or on the American side at the almost end of the war in 1945.
allied countries (great Britain,France,russia and japan joined in weeks later,and Italy joined later)
Technically, no. Italy was allied with Germany and Austria before the war, but, believing that Germany's actions against Belgium negated the alliance treaty, joined the war on the side of the Allied Forces. It only fought on one side during the war.
Italy entered WWI in 1915 on the side of the Entente (Allies).
Italy fought on the side of the Allies in World War One. In World War Two, Mussolini allied Italy with Germany and declared war on Britain and France (and later the USA). In 1943 Mussolini was ousted and Italy joined the Allied powers.
Italy switched sides from the Triple Alliance, which was made up of Austria-Hungary, Germany and Italy, or the Central Powers to the Triple Entente's side made up of Russia, England, France and later the U.S. also.
Britain, France, Italy, Russia (dropped out in the war), USA ( eventually joined in 1917), and 21 smaller countries.
