Who are Greeks from Santorini?
Greeks from Santorini come from Thera in the southern Cyclades, a volcanic island with ancient Aegean, classical Greek, Byzantine, Venetian, Ottoman, and modern tourism-era history. The island's population history is tied to Cycladic maritime networks, settlement continuity, and migration.
Greek is the main language. This reference has a small sample size, so Santorini should be interpreted carefully and compared with nearby island references such as Chios, Ikaria, Crete, Kalymnos, Kos, Astypalaia, Kythira, Karpathos, Nisyros, and Chania.
As a genetic reference, Greek Cyclades Santorini is useful for comparison with North Aegean Chios, Ikaria, east Crete, Kalymnos, Kos, Astypalaia, Kythira, Karpathos, Nisyros, and Cretan Chania.
