The Greek state has systematically pursued a policy of Hellenisation following its independence from the Ottoman Empire in the early 1830s. This ideology included replacing all geographical and topographic names with revived names rooted in Classical Greece – that is, any name deemed foreign, divisive against Greek unity, or considered to be "bad Greek" was hidden or assimilated. The names that were considered foreign were usually of Albanian, Slavic or Turkish origin. Byzantine Greek was considered bad Greek at the time of the establishment of the state until well after the Balkan Wars; accordingly those places were also renamed.
The aim of the name changes was to cover the memory of the "dark past": meaning Roman, Frankish, Venetian, and especially Turkish rule. The name changes followed the territorial expanses of Greece and continued into the Greek Republic. They occurred in the Arvanite settlements in central Greece since 1830, in Thessaly since 1881, after the Balkan Wars in Macedonia since 1913, and Western Thrace since 1920. The last name changes occurred in 1998.
