Who were Russia's friends in World War 1?

During World War I, Russia was part of the Allies, which primarily included France, the United Kingdom, and later Italy and the United States. These nations collaborated against the Central Powers, which included Germany, Austria-Hungary, and the Ottoman Empire. Russia's alliances were driven by mutual interests in countering German expansion and maintaining balance in Europe. Additionally, Serbia was an important ally, particularly in the conflict's early stages, as the assassination of Archduke Franz Ferdinand in Serbia was a key event that triggered the war.
