States that are under the threat of war, or are already drawn into armed conflicts, have always sought to increase their chances of victory by concluding military alliances. Even fighting against a large and militarily strong enemy, the armies of several small countries can jointly defeat him - this was demonstrated, for example, by the First Balkan War. Test your knowledge and try to identify past coalition wars based on the lists of states that took part in them.
(Note: in conflicts with a very large number of participants, their lists may be incomplete).
