The Treaty of London (1913) ended the war, but no one was left satisfied, and soon, the four allies fell out over the partition of Macedonia. In June 1913, Bulgaria attacked Greece and Serbia, beginning the Second Balkan War, but was beaten back. The Treaty of Bucharest (1913), which concluded the Second Balkan War, left Greece with southern Epirus, the southern half of Macedonia (known as Greek Macedonia), Crete and the Aegean islands, except for the Dodecanese, which had been occupied by Italy since 1911. These gains nearly doubled Greece's area and population.
