The Greco-Turkish War of 1897 or the Ottoman-Greek War of 1897, also called the Thirty Days' War and known in Greece as the Black '97 (Greek: Μαύρο '97, Mauro '97) or the Unfortunate War (Ατυχής πόλεμος, Atychis polemos; Turkish: 1897 Osmanlı-Yunan Savaşı or 1897 Türk-Yunan Savaşı), was a war fought between the Kingdom of Greece and the Ottoman Empire. Its immediate cause involved the status of the Ottoman province of Crete, whose Greek-majority population had long desired union with Greece. Despite the Ottoman victory on the field, an autonomous Cretan State under Ottoman suzerainty was established the following year (as a result of the intervention of the Great Powers after the war), with Prince George of Greece and Denmark as its first High Commissioner.
