Former toponyms of Greek places

Geographical name change in Greece is the Greek state's systematic replacement of non-Greek geographical and topographic names within Greece with Greek names as part of a policy and ideology of Hellenization. The main objective of the initiative has been to assimilate or hide geographical or topographical names that were deemed foreign and divisive against Greek unity or considered to be "bad Greek". The names that were considered foreign were usually of Turkish, Albanian, and Slavic origin. Most of the name changes occurred in the ethnically heterogeneous northern Greece and the Arvanite settlements in central Greece. Place names of Greek origin were also renamed after names in Classical Greece.

The policy commenced after the independence of Greece from the Ottoman Empire in the early 1830s, after the territorial expanses of Greece and continued into the Greek Republic. To this day use of the old Turkish, Albanian, or Slavic placenames by authorities, organisations, and individuals is penalized under Greek law.

The area that is today Greece was inhabited by various peoples throughout history, and the country's toponyms reflect their diversity of origins. The hellenization of toponyms in Greece started soon after Greek independence, as part of the process of shaping Greek national identity. Many placenames in Greece of non-Greek origin were replaced by "ancient or pseudo ancient names that were supposed (sometimes erroneously) to have some connection to the area". For example, the ancient name of Piraeus was revived in the 19th century, after it had been called Drakos in Greek, Porto Leone in Venetian, and Aslan Limanı in Turkish for centuries, after the Piraeus Lion which stood there.

In 1909, the existence of large numbers of non Greek place names were a nuisance to the government. In 1909 the government-appointed commission on toponyms report that every one village in three in Greece (30% of the total) should have its name changed (of the 5,069 Greek villages, 1,500 were considered as “speaking a barbaric language”.
