An example of this is the Triple Entente, which consisted of France, Russia, and Britain forming a mutual defense agreement. On the other hand, Germany, Austria-Hungary, and Italy formed the Triple Alliance, creating a counterbalance to the Triple Entente.

This system of alliances ultimately escalated tensions and contributed to the rapid spread of the war once it started in 1914.in simple words
