Treaty of Constantinople (1897)
The island of Crete was a part of the Ottoman Empire, but had a majority Christian population which had rebelled several times to achieve union with Greece. During another such revolt in 1897, on 2 February 1897 Greek troops landed in Crete to annex the island. This led to the outbreak of war, the so-called 30 Days War, between the Ottoman Empire and Greece. It was fought mainly in Thessaly and Epirus. In Thessaly, the superior Ottoman army commanded by Edhem Pasha defeated the Greeks and captured much territory. Greece sued for peace and the Great Powers of Europe intervened in order to force the Ottoman government to return the majority of the lands occupied during the war, and to grant autonomy for Crete.
- Thessaly, which had been occupied by Ottoman forces, was to be largely returned to Greece with changes in the pre-war border line in favour of the Ottomans (northern Thessaly was ceded to the Ottoman Empire, while southern Thessaly was restored to Greece.)
- Greece agreed to pay heavy reparations.
- The Ottomans would not withdraw before the reparations were paid.
- The Ottomans agreed to promote the status of Crete as an autonomous state under Ottoman suzerainty.
Although the Ottoman army was victorious in the field, the Ottoman Empire did not benefit from the victory. The suzerainty over Crete proved to be completely ineffective and Crete unilaterally declared union with Greece in 1908. This was formalized after the Balkan Wars, with the island joining Greece on 1 December 1913. In the 1923 population exchange between Greece and Turkey, the Muslim population of the island was transferred to Turkey.
