The Triple Alliance in Europe before World War I was made up of Germany, Austria‑Hungary, and Italy.

Core answer

  • The countries allied by the Triple Alliance (formed in 1882) were:
    • Germany.
* Austria‑Hungary.

* Italy.
  • This alliance was a defensive pact, renewed several times up to the First World War.
  • When World War I began, Italy chose neutrality and later left the alliance, but the original Triple Alliance still refers to these three countries.
