When did the Greek alphabet reach Greece?

The Greek alphabet reached Greece in the 9th or early 8th century BCE. Following the collapse of the Mycenaean culture and the disappearance of Linear B writing, Greece had experienced a period of several centuries where it was largely nonliterate.12

The Greeks adopted their alphabet from the Phoenician alphabet through commercial contacts. While the Phoenician script consisted of consonants, the Greeks made a major innovation by adapting certain signs to represent vowels, creating a more accurate writing system for their language. The earliest surviving alphabetic inscriptions, which include brief fragments of hexameter verse, date to approximately 730 BCE.2341
