Final answer:
The Triple Alliance and Triple Entente were developed through a series of treaties between major European powers prior to World War I. The Triple Alliance involved Germany, Austria-Hungary, and Italy, while the Triple Entente included France, Russia, and Great Britain. These alliances set the stage for the global conflict that ensued with the onset of World War I.
Step-by-step explanation:
The Triple Alliance and the Triple Entente were central to the alliances formed before World War I. The Triple Alliance was first established by a treaty of alliance between Germany, Austria-Hungary, and Italy. In response to the increasing militarism and power of this alliance, the Triple Entente was formed, conjoining France, Russia, and Great Britain through a series of treaties and mutual defense alliances.
These treaties were not signed at a single event but developed through various diplomatic negotiations. For example, the Triple Alliance was conceived after 1879 when Germany and Austria-Hungary formed the Dual Alliance, which later included Italy. On the other side, the Triple Entente evolved after 1894 when France and Russia agreed to a mutual defense alliance, which was later solidified by the inclusion of Great Britain in 1907.
The alliances exemplified a divided Europe with the Triple Entente and the Triple Alliance setting the stage for the vast global conflict known as World War I. It was the assassination of Archduke Franz Ferdinand and subsequent political maneuvers that transformed these alliances from defensive postures into wartime coalitions.
