Many local variants of the Greek alphabet were employed in ancient Greece during the archaic and early classical periods, until around 400 BC, when they were replaced by the classical 24-letter alphabet that is the standard today. All forms of the Greek alphabet were originally based on the shared inventory of the 22 symbols of the Phoenician alphabet, with the exception of the letter Samekh, whose Greek counterpart Xi (Ξ) was used only in a sub-group of Greek alphabets, and with the common addition of Upsilon (Υ) for the vowel /u, ū/.[1][2] The local, so-called epichoric, alphabets differed in many ways: in the use of the consonant symbols Χ, Φ and Ψ; in the use of the innovative long vowel letters (Ω and Η), in the absence or presence of Η in its original consonant function (/h/); in the use or non-use of certain archaic letters (Ϝ = /w/, Ϙ = /k/, Ϻ = /s/); and in many details of the individual shapes of each letter. The system now familiar as the standard 24-letter Greek alphabet was originally the regional variant of the Ionian cities in Anatolia. It was officially adopted in Athens in 403 BC and in most of the rest of the Greek world by the middle of the 4th century BC.

Lycia (Lycian: 𐊗𐊕𐊐𐊎𐊆𐊖 Trm̃mis; Greek: Λυκία, Lykia; Turkish: Likya) was a geopolitical region in Anatolia in what are now the provinces of Antalya and Muğla on the southern coast of Turkey, bordering the Mediterranean Sea, and Burdur Province inland. Known to history since the records of ancient Egypt and the Hittite Empire in the Late Bronze Age, it was populated by speakers of the Luwian language group. Written records began to be inscribed in stone in the Lycian language (a later form of Luwian) after Lycia's involuntary incorporation into the Achaemenid Empire in the Iron Age. At that time (546 BC) the Luwian speakers were decimated, and Lycia received an influx of Persian speakers. Ancient sources seem to indicate that an older name of the region was Alope (Ancient Greek: Ἀλόπη, Alópē). Lycia fought for the Persians in the Persian Wars, but on the defeat of the Achaemenid Empire by the Greeks, it became intermittently a free agent. After a brief membership in the Athenian Empire, it seceded and became independent (its treaty with Athens had omitted the usual non-secession clause), was under the Persians again, revolted again, was conquered by Mausolus of Caria, returned to the Persians, and finally fell under Macedonian hegemony upon the defeat of the Persians by Alexander the Great. Due to the influx of Greek speakers and the sparsity of the remaining Lycian speakers, Lycia was rapidly Hellenized under the Macedonians, and the Lycian language disappeared from inscriptions and coinage.
