The Triple Alliance in 1913, shown in red.The Triple Alliance was the military alliance between Germany, Austria-Hungary, and Italy, (as opposing the Triple Entente which consisted of an alliance between Britain, France and Russia), that lasted from 1882[1] until the start of World War I in 1914.[
From 1882-1914 the three countries made up the Triple Alliance, but Italy's membership was virtually meaningless.
The triple alliance was formed in 1882 between Germany, Austria Hungary and Italy, who was not fully trusted due to its lack of power and industry. Unlike the triple Entente (Britain, France and Russia), the triple alliance was formed from one large agreement and not three several agreements between each of the powers.

The Triple Alliance, formed in 1882, was a defensive military alliance between Germany, Austria-Hungary, and Italy. The risk of this alliance was that it created a strong bloc of powers that could potentially escalate conflicts and increase tensions with other nations, particularly with their rival alliance, the Triple Entente. This eventually contributed to the outbreak of World War I in 1914.
The Triple Alliance (1882) included all three countries. Italy, regarding their "common defense" pact not to apply due to Austrian aggression, did not join Germany and Austria-Hungary in World War I (1914), and actually fought against Austria later in the war.
. Military alliances were made to get back lost territories; countries joined together for mutual military help. In 1882, Germany, Austria, Hungary, and Italy formed the Triple Alliance. A Triple Entente was agreed among France, Great Britain, and Russia in 1907. Their agreements divided Western Europe-the Triple Alliance against the Triple Entente.
