Answer :
The cause of WWI related to world powers entering formal friendships is known as alliances. During the lead-up to World War I, various countries formed alliances with each other in order to strengthen their military and political positions. These alliances created a complex web of interlocking agreements that drew multiple countries into the conflict when it eventually erupted.
Examples of these alliances include the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (comprising Germany, Austria-Hungary, and Italy). When one country within an alliance was threatened or attacked, the other countries in the alliance were obligated to come to its defense, leading to a domino effect of countries entering the war.
These alliances played a significant role in escalating the conflict and turning a localized issue into a global war involving multiple world powers. By understanding the concept of alliances as a cause of WWI, one can grasp how interconnected relationships between nations can impact the course of history.
