Which countries were part of the triple alliance?

The Triple Alliance included such European powers as:

German Empire.
Austro-Hungarian Empire.
Italy.

This alliance was formed at the end of the 19th century and the purpose of its creation was a new division of the world and, in particular, the colonial territories. This was due to the fact that the above countries, unlike other large European countries (England, Spain, France), did not have overseas colonies. This greatly hampered their economic development. It was the war unleashed by the allies in 1914 that became known as the First World War.
