Answer:
The Triple Entente was an example of a factor known as alliance systems that contributed to the outbreak of war in Europe. The Triple Entente was a military alliance formed in the early 20th century between France, Russia, and Britain. It was formed in response to the growing power and ambitions of the Central Powers, primarily Germany and Austria-Hungary. The alliance system created a complex web of commitments and obligations, where an attack on one member could potentially lead to a wider conflict involving all allied nations. When the assassination of Archduke Franz Ferdinand of Austria-Hungary in 1914 triggered a series of events, including the declaration of war by Austria-Hungary against Serbia, the alliance system rapidly escalated the conflict. It led to the involvement of multiple nations and ultimately resulted in the outbreak of World War I.
