Name of the sides in the world wars?

The Triple Alliance, also known as the Central Powers, grew out of the close relationship that developed between the leaders of Germany and Austria-Hungary during the last tree decades of the the 19th century. In 1879, the governments of the two empires formed the Dual Alliance, a defensive pact that ensured reciprocal protection from a Russian attack and neutrality in case of an attack from any other power. In 1882, Italy joined the pact, creating the Triple Alliance.

The Triple Entente, referred to as the Allies, originated in a series of agreements between Britain and France (1904) and between Britain and Russia (1907) that aimed to resolve colonial disputes. Between 1907 and 1914 cooperation between the leaders of Britain, France, and Russia led to the signing of a military pact in the summer of 1914.
