Map of the new territories acquired by Greece after the Treaty of Berlin in 1878. Ioannina did not in fact become Greek territory until the 1913 Treaty of Bucarest, after the Balcan Wars. The proposition that it be ceded to Greece in 1878 was rejected by the Congress of Berlin due to the reaction of the Ottoman side. With the Treaty of Berlin the Kingdom of Greece acquired Arta and adjacent area.
