The history of Leros is rooted in the prehistoric era and is closely intertwined with ancient Greek mythology. According to legend, this island was chosen by the goddess of the hunt, Artemis, as her personal domain.
- The first historically confirmed inhabitants of the island are considered to be the Carians, Cretans, and Leleges, who arrived from Asia Minor.
- Subsequently, the island was colonized by the Ionians from Miletus, which determined its cultural path of development.
- Leros is mentioned by Homer in the epic poem 'The Iliad': together with neighbouring Kalymnos, the island sent ships to participate in the Trojan War.
The transformation of Leros into a significant point on the map of the Aegean Sea was due to a combination of natural and geopolitical factors.
- Unique geography: The island possesses a heavily indented coastline. Lakki Bay is one of the deepest and safest natural harbours in the entire Mediterranean, making the island an ideal location for fleet anchorage.
- Connection with Miletus: A close political and trade alliance with the powerful city-state of Miletus ensured protection and stable economic growth for Leros during the ancient period.
- Participation in alliances: In the 5th century BC, the island became a member of the Delian League under the aegis of Athens, strengthening its status in the region.
Early life on the island was characterized by a developed spiritual culture and active maritime activity.
- Cult of Artemis: The religious centre of the island was the sanctuary of the goddess in Partheni (the modern airport area), upon the ruins of which Christian churches were later erected.
- Intellectual life: Leros became the birthplace of the famous ancient Greek logographer and historian Pherecydes (5th century BC).
- Economic base: The foundation of prosperity was maritime trade, fishing, and agriculture, which flourished in the fertile valleys of the island.
