How did the system of alliances help contribute to, rather than stop, the
coming World War?

Explanation:

The alliances system meant that a local conflict could easily result into an intimidating global one. The overall cause of World War was the assassination of Archduke Franz Ferdinand. Nationalism was a great cause of World War one because of countries being greedy and not negotiating.

The Triple Entente was made up of France, Britain, and Russia. The Triple Alliance was originally composed of Germany, Austria–Hungary, and Italy, which remained neutral in 1914. As the war progressed, each coalition added new members. Japan joined the Entente in 1914.
